ADT build

[Efroeh]

Hi everyone, I've been tossing around the idea of building a articulating dump truck for some time. So this winter I thought i would give it a try. Now this will not be close to some of the amazing builds that are on this site. This will be more a cut, weld, kinda build. Ive got ton of inspiration from andyathome rock truck build. It won't be modeled after any particular truck but I do have a small toy one from my earlier years that I've been using for reference. Here's a picture of it. .

https://s1.postimg.org/3n0s2k3hxb/Screenshot_20171106-214617.png (https://postimages.org/)

So i started with some half inch square tubing i had kicking around from a boat trailer build.

https://s1.postimg.org/58u36d94yn/20171028_212539.jpg (https://postimages.org/)

I'm gonna run 6 25rpm geared motors.

Rims and tires I'm gonna use the same as andyathome used the wild willies. I got some closed foam inserts for it so the tires won't squat too much with the weight of it. So I got some tubing that the motors would fit inside as I don't have a lathe to turn the inside to size. Drilled some holes threaded it for some bolts to hold the motors in there.

https://s1.postimg.org/280hbnrr0f/20171028_212524.jpg (https://postimages.org/)

Cut some metal to attach the motors to the frame so it will pivot in the middle to have some suspension like movements.

https://s1.postimg.org/2xj9o0f067/20171028_212516.jpg (https://postimages.org/)

Got the bracket cut out and tacked to the tubes for the motors and bolted to the frame. The front I hard mounted it to the front frame.

https://s1.postimg.org/9b9mp34awf/20171029_204117.jpg (https://postimages.org/)

For steering I'm gonna go with a 6rpm motor.
http://www.robotshop.com/ca/en/12v-6rpm-613oz-in-gearmotor.html

I got some different wheels comming with more offset to bring the tires in towards the frame more hopefully they will work. Not sure what I'm gonna use for lifting the box either some actuators or a screw lift. I'm up at work now and hope to get some done when I get home. It'll be a slower process but I have lots of time. The body i will try my hand at styrene.

[TheBennyB]

Already some great progress. Looks to be real deal!

[Northern Farmer]

Nice progress so far keep it up!

[Efroeh]

Thanks guys. I've thought out the swivel and hope to get that completed and everything welded up. Also want to finish off the pan for the front. I've made a deal with a buddy and bought his princess auto ( Canadian harbour freight) lathe and mill so might help with more delicate areas.

[RCP57]

Sweet start!

[skeeter]

Great start! :popcorn: I'll be watching this one, subscribed.

[Efroeh]

I found some actuators that look like rams and emailed for more info. Hers the link to see if anyone else inquired about them.

Those are neat, me likes it a LOT! Please do let us all know how well they work out for you. Those would be PERFECT for a few projects I have awaiting to be started on.

I will for sure. I think there not gonna be cheap by no means but will have to see compared to hydraulic they might be as good and with out the headaches.

[skeeter]

Most likely not cheap at all. I've used the Firgelli/Acutronik actuators on stuff & they run about $70 U.S.D. per unit.

[Efroeh]

Ok so I got some prices back for those actuators and there not cheap. Prices are 270 to 290 for 100mm ram and 150 each. Plus a controller and programmer about 150 each. Which is a little bit much since hydraulics could be done for that price.

[skeeter]

OUCH! For that price, I'll stick with the square type from acutronix.

[Efroeh]

OUCH! For that price, I'll stick with the square type from acutronix.

My thoughts also.

[SteinHDan]

Very nice build!

I'm looking forward to the updates with a lot of anticipation!


For some while I've been pondering with an ADT build myself, but it likely won't happen for real for a few years more.

Anyways, I was playing with the idea of using gas springs for the bed lift (very cheap) and then a powerful gear motor to pull it back down again with a wire rope. I was thinking something like 2x15kg gas springs 150mm stroke:
- https://www.aliexpress.com/item/free-shipping-30-to500N-force-380mm-central-distance-150mm-stroke-pneumatic-Auto-Gas-Spring-Shock-absorber/32296134474.html

and this gear motor:
- https://www.ebay.com/itm/231911256302

And then some wire rope around 1mm thickness:
- https://www.ebay.com/itm/222599707119


There is very little extra room to go on for the cylinder with the very long stroke they have to have to get a proper angle on the bed when tipping. I don't think an inline electric motor (like in the electric actuators) will enable you to get a cylinder that mounts in the normal positions or will provide the normal tipping angle for the bed.


Best regards,
Stein :-)

That's a good idea for lifting the box. I'm gonna try the actuators from actuonix first as I have a few sitting around.

Also I think I'm gonna change my mind with steering and go to a large scale servo. The gear motor would be good but can't get it to auto center and be harder to control I think.

[Cooper]

Auto centering for steering is nice, my haul truck uses hydraulics and it is difficult to drive, centering would be nice. I think the German ones have a pot wired into the motor for centering the adt, guess I’m saying it can be done but may be too much electronic thought for me :). Keep the progress pics coming. :)

[SteinHDan]

You can get any gear motor to be an RC servo by using a controller board like this one:
- https://www.ebay.com/itm/172264924286
(there are more types)

With this setup, you don't even need to have the pot on the motor output shaft, so for example, you could have a screw drive to lift the bed, but then mount the pot on the bed pivot point. The controller would run the motor to get the right angle on the bed, regardless of the mechanism used to get it there. Also, you could use a linear pot. Or even a multi-turn pot, e.g. with 10 turns to give the full range. Lots of options.


You can get them pre-mounted on gear motors so that it's actually like a normal servo (except that they require 12v / 24v additional power input).
- https://www.ebay.com/itm/131683084318
- https://www.ebay.com/itm/131683049823
- https://www.ebay.com/itm/141859318550

Lots of gear ratios and motor types to choose from.

I think the benefit of these servos, is that they are quite cheep and also that the gear output ratio match much better what you want for the steering servo than a normal RC servo does. They are mostly much too quick and not so strong.


You could also build this from scratch very cheaply using an arduino uno, a monster motor shield, the gear motor of your choice and a 10k pot. I think you could build the full controller then for less than $15.

There is a guy that has build a servo with this approach and described it here:
- http://www.instructables.com/id/DIY-Servo-Motor/



I wasn't actually thinking of having a auto-centering steering in my build. But when you mention it, it's a bit of a nuisance to continuously heard the truck to just go straight. So maybe I'll go that route myself.

I was also thinking a lot on the steering and how it plays with having one gear motor on each wheel. If your gear motors on the wheels have a high reduction, they will not turn when you steer. Rather they will just stay put and make it very difficult for the steering motor to do the steering. This is no problem on the original of course, since it has a differential between the left and right wheels and would allow the wheels to turn in the opposite directions when steering.

So I was thinking to combine a steering gear motor with the approach I used for the Bruder loader conversion:
- http://rctruckandconstruction.com/showthread.php?t=12500
It has tank-style driving for the left and right wheels. So when you steer left, the right motors are run faster and the left motors are run slower on the front and the reverse on the back.
I'm thinking about combining these two for the ADT, so that the tank-style steering will help the steering gear motor turn the wheels, especially when standing still or going slowly. I'l thinking on ramping the tank-style steering on the wheels so that when going fast forward or backward, there is no tank-style steering but only normal full throttle on both the left and the right.

Wow awsome explanation of that. I wondered about the drive motors not steering well with the gear ratio I have. But I'll see how it goes. I like the idea of the tank style steering. I'll look into the controller for the gear motor for steering. I'm not very confident when it comes to electrical stuff so I'll see what I can do. Also wonder if that controller would work with 11v. Id like to use a 3 cell battery.

[skeeter]

Yes sir, Stein is a sharp cookie. He knows how to explain things in a manner that you get an idea what he's trying to say. He's got a knack for explaining complex things in simple terms, ESPECIALLY when it comes to the confusing, complicated computers!

[Cooper]

yes thanks for that information. and easy to read, now I have no reason for not doing that!! another side project to add ;) will be referring back to this information when time comes, thank you again, love this forum and the people on it!! efroeh, keep posting info on this if you go this way, will keep watching,,,,,

[Efroeh]

So I bought the 110kg servo that Stein had posted on ebay. Now the waiting game to receive it. **** shipping quote of dec 12 to jan 22. I hate waiting for that boat. Thanks again for the info. I may ask a few questions as to how to hook it up.

[skeeter]

I'm sure he'd be more then happy to help you. That man has helped me tremendously with my projects!

[SteinHDan]

Sure, that's super easy. It has a standard servo lead. Just connect that to your receiver as normal. It also has a 12V power (red/black) and you just connect these directly to your 3S battery.

Ok perfect thanks again.

[Efroeh]

Ok so not much happened this short set of days off that I have. My band saw blade didn't want to cut metal anymore. So I'm at a bit of a stand still till I get a new blade. Hope next time I'm home I'll get the swivel done, get it all welded, and start the dump box.

[skeeter]

Bummer! Sorry to hear you have to get a new blade. I think those things are spendy, aren't they?

[Efroeh]

Bummer! Sorry to hear you have to get a new blade. I think those things are spendy, aren't they?

I don't think it'll be too bad. Needs to be fixed so it is what it is I guess.

[Efroeh]

Ok got a little bit done not near as much as I'd like but life and a new dozer is taking me away from the project. Got out there today and did some things. Started on the dump box after welding up the frame front and rear. Wow I haven't welded anything in some time and it showed. I did the box in 22 gauge steel and I think I'm gonna do a Skelton type frame to give it some extra strength. Also have some mounting place to the rams for lift. Still waiting for the boat to get here with my steering servo motor thing from China. On to picks

Hi Looking Good

Should be great when finished looking forward to the extensive testing phase.

[markturbo]

Cool build, good idea for the drive motors. Good info here too on the board for controlling servos for a drive setup.

[Efroeh]

Ok so I think I'm gonna scratch the 22 gauge dump box and build it out if 16 gauge and not have the seam. Take a little longer with vending and measuring but I think it'll be worth it.

[Efroeh]

Ok a long over due update after fighting with my band saw going threw blades like lube on a porn shoot I broke down and with a early birthday gift from my wife bought a plasma cutter. I got the box cut out of 16 gauge steel and bent and tacked together. I am hoping tonight I can get my swivel mount cut out and fitted then off to getting the steering motor servo mounted. I did not realise how big it is. takes alot of room but will be worth it. I have some ideas as to how I'm gonna mount the rams I think under the box will work.

Great job your doing,

You may find your geared motors a little on the slow side though at 25rpm

I did the whole self centering thing on my JD 9530 build: JD 9530 build thread (http://www.rctruckandconstruction.com/showthread.php?t=7617)

Pretty sure I used 80rpm motors on that (for the drive that is, cant remember what I used for the steering)

ya not sure on the speed. I asked Andy on his adt build and he said he used 30 rpm so we shall see. if not they can be used for somthing else I'm sure.

[Lil Giants]

Your project is shaping up good Evan :cool:

My B50 has 110rpm motor output with 120mm diameter tires, it's less than walking speed. About 480 sized motors with 100:1 planetary on 3s.

Ok I tried using the servo today and it does not work. I powered it with a 3s battery and It wouldn't move. wonder if it didn't work right from get go. now not sure what to do.

[SteinHDan]

Post a picture of it. Maybe it is of the type that has a selector for the control signal, and you need to set it to PWM or Servo.

Got some things done in the last couple evenings. the swivel is completed and the hinges for the dump box done as well. got a pretty good idea what I'm gonna do with the rams for the dump also. Here are some pictures.

Going to have some real offroad capability :cool:

[Cooper]

Agreed, lots of articulation. One ADT is, or has been on my to do list for a while. Like watching these trucks meander through the rough stuff. Looking good , keep the progress pics coming.

[Efroeh]

I need some opinions on dump angle. I have right now with the actuators I have and with good lifting power about 35 deg. think that's enough to clean the box?
https://s17.postimg.org/git118fpr/20180219_201956.jpg (https://postimages.org/)

[Claus]

For marbles, soy beans or Legos yes, for dirt no.

https://s.yimg.com/lo/api/res/1.2/mg8AmugoDrqzrVucQNQP4w--~B/YXBwaWQ9eWlzZWFyY2g7Zmk9Zml0O2dlPTAwNjYwMDtncz0wME EzMDA7aD00MDA7dz01MzM-/https://st.mascus.com/imagetilewm/product/3197d3eb/caterpillar-730-almost-new-tyr,bf297a7a.jpg.cf.jpg

[Efroeh]

so I found a chart with the highest angle being 45 for wet clay everything else was less. I played around with different ways of gaining more angle even had more actuators involved but I think I'm gonna break down and order some longer ones. hope to get close to 50 deg which I think will be lots. I'll show some pics of what I came up with before I decided on the longer rams. it gained me 10 more deg of angle.
https://s13.postimg.org/uybprg0qv/20180219_205820.jpg (https://postimages.org/)
https://s13.postimg.org/ijoxr4oo7/20180219_205809.jpg (https://postimages.org/)
the 30 mm actuator was sitting horizontal and would push the longer one so it would gain tilt angle. if have to build some sort of a skid pan for it to slide on as the little ram was bending.

[Lil Giants]

Yeah, your chart is quite accurate for scale too, anywhere between 35 - 40 will be fine for rock or dry dirt. If you do load any wet, don't pack it down with the bucket & it should slide out. A good acetone wash & metal-etch primer, keep the box inside as slippery as possible.

From Claus' pic, notice the location of the dump cyls being low & outside of frame? I noticed the gap you have between tires & frame, dual long Actuonix actuators would give you the most lifting power in this location.

You didn't put an elevated tail in your box? yet?

[Efroeh]

Ya I've seen the rams out side of the box not under. I'm gonna order some longer rams and see how it looks on the outside and how much it would lift. As for the elevated tail I never even thought of that. probably will leave as is for now. maybe could add it on after or build a new box.

[SteinHDan]

https://s17.postimg.org/p7sznohgf/20180218_191458.jpg (https://postimages.org/)

The switches look to be in the right position. Could you also share a picture of it when you have the servo cable connected?

And if it still doesn't work, maybe try the switch in "S" position also?
Here is a lot more info on the servo:
- https://www.aliexpress.com/item/Free-shipping-ASMC-02A-High-power-high-torque-servo-the-24V-260kg-cm-0-12s-60/1899809165.html

And a couple of demo videos:
- https://www.youtube.com/watch?v=rPN92jVIs6o
- https://www.youtube.com/watch?v=GwRxrp4nzDA

The servo is supplying 5V on the 5V servo lead and it can power your receiver this way, but if you are powering your receiver from a different source, then disconnect this red lead on the servo cable. Also, it can only supply 20ma 5V, so if you have any other normal RC servo on the same receiver I suggest disconnecting the red servo wire and power the receiver from some other power source.

I'm gonna try it again tonight I will use it to power my servo and see if that'll make a difference. also the link for more info just said it was not avaible anymore.

https://s17.postimg.org/5vqhnoevj/20180220_195206.jpg (https://postimages.org/)

I have a 3s Lipo powering the servo and no power is feeding the receiver. I noticed on the videos that it has a light one when working this does not.

[Efroeh]

so I ordered another servo from China think I wired it up wrong and fried it. But it's the same as what I ordered again so I got it mounted up. Also the rams came in and got them mounted. I went with lifting under the box instead of on the sides, it was easier and I tried on the sides it wouldn't give me enough angle of dump before it hit the tires. Now I have **** near 60 deg of dump angle which will work great.

I'm really impressed with your build and your ideas. This has helped me on the ADT I've be planning to build in near future , i'll be watching for sure.

Thanks for the kind words.

I got the replacement steering servo in from the slow boat. I am amazed at how much power it has WOW. I would not want to get a finger in it while it's turning. works great nice and quiet also. hope to get some time this set off to work on the cab now. I've never worked with styrene and it's a learning curve that's for sure.

I'm SO happy you got the steering servo working. I felt really bad about telling you to get one, and then it didn't work. I'm really relieved now! :-)

Looking forward to more great pics!

ok i have a question about wiring up the drive motors. If I do one side the proper way positive to positive negative to neg. do I need to do the other side the opposite so they turn the same direction? I really think in over thinking this but would like some advice from the more experienced builders on this great site.

Also I started on the body think I might do something to cover the front wheels not sure yet.

Yes. And you only need one esc, something over 20amps. If your dump
Actuators need an esc too, then I'd recommend a 2x25 Sabertooth. I always knock the heat sinks off, saves space.

Thanks Joe.

I found a axial ae5 esc in my bench of parts would this work?

Edit forgot to put I just need this to run my drive motors the actuators are actuonix ones.
