In this Instructables I will show how to build a simple and effective platform for any Robot project or Remote Control project. This Tank platform is great base for any robot design as it goes over rough terrain with ease. The other great plus with this design it can carry a lot of weight for there size. So there is endless possibles with this design.

The motor this platform uses can be control by any means. I use an cheap RC car to control the motors.The gear box and motor combo can deliver different gear ratio settings to suite your application. The gear ratio I use is 114.7:1 @ 4.5V. This ratio work well with the remote control that I use. I have try other ratios but this over heat the transistors on the RC board.

The this Tank platform use two motor so it use skid steering to turn. So you need least need a two channel RC car to make this project but most RC car have at least two channels anyway.

I will show both the new and old design. The old design will be known as Mk1 and the new design Mk2.

Step 1: Tools and Parts

<p>how big is this, because i want to scale it up and make a Rc esky</p>
<p>This might be a stupid question, but for skid steering, don't you need one motor to move forward while the other moves backward? So how does letting go of the left motor control switch will make a right turn? I am just not clear on the steering mechanism used. Thanks. </p>
David97, can u send me plans how to do yours?
Thanks for this instructable, here is a picture of my one. I am using a arduino duemilanove and a l298 motor driver board. The whole thing runs on 9.6V and uses PWM to regulate the voltage. These are really great at climbing!
How good is the torque that this gearbox offer?
Should i use the contoller included with R/C car I use or should I use a different one?
tamiya rules<br>
Scorpio Technology ( http://www.scorpiotechnology.com.au ) have 2 band Radio Controls for around $13 and will have 4 Band Infrared controls for around the same price very soon. They also have cheap motor gearboxes, gears and other things.
These kits are perfect for robotics hey? I use them often too! Sometimes the tracks fall off, but only on thick carpet. I hope they never discontinue this kit. I don't know what will do without it hahaha. Great job!
I found this http://www.amazon.com/Thunder-Tumbler-Remote-Controlled-Car/dp/B000VRJINM/ref=pd_sim_k_2<br><br>It includes 8 leds inside, 2 geared motor in full enclosures, and a tank style remote control layout. DO NOT buy it from Amazon. Its $10 at CVS if your in the US. Its great and has moderate range!
what size are the nuts and bolts you used
I made a similar platform but without the RC control... I included a suspension system on the road wheels with paperclips. now I have smoother ride and better traction on different terrains... Check it out!
spy bot? rotating cam to spy and 2 more for foreword + reverse?
You will need to find a 3ch remote system and add another motor<br />
ok, thank you...
i am a ditz
&nbsp;use a adder-subtracter. heres a lego one.&nbsp;<a href="http://www.youtube.com/watch?v=s-DDm4plRuw" rel="nofollow">www.youtube.com/watch</a>
can you let me know the price of the parts in total please?brilliant Instructable. I think I'll make this if it's within my current price range
Just updated the instructable to include the prices, cost can be kept down by what you can find in your junk box <br />
thanks a bunch. unfortunately, I have nowhere near enough money for this <br /> =.( so I will look through my stuff and make a crappier version of this if I can
This is insane i was trying to make an rc tank and i got all three parts and a car from good will but the circuit board didn't work but i will try again. nice tank though can you post a video.<br />
With the rc car all you do is find the wires that go to the steering motor or solenoid, that will be motor 1 and the wires that goes to motor that drives the rc car those wires will go to motor 2&nbsp; <br />
&nbsp;This Looks sweet i cant wait to make this.
Totally sweet faved and 4.5 stars thanks for the sweet idea i am making one
if u wanna make a nplatform just get the remote control platform from tamiya
ids there a website or something for that? if there is, post it please,
no u find a lot of this stuff in model stores try chinese model stores
chinese? like, in china? or in chinatown?
like chinese places (malls, hobby stores) what country u live in.???
i have that kind of toy too. i've always wanted make it remote controlled.
take this, add a turret thing, add the nerf nade launcher, and you will kill in nerf tag.
how big are these things? like 8 inch by 5 inch?
The plate is 6.5 inch by 2 1/4 inch. The tracks add about an inch in width total.
huh, smaller that they looked...
Yeah, I have one and I measured it. You can fit a lot of electronics onto one, though. They can fit like 2 arduinos or something.
Is this the right gearbox system: <a rel="nofollow" href="http://www.amazon.com/Tamiya-America-Inc-Motor-Gearbox/dp/B00061HHQS/ref=sr_1_1?ie=UTF8&s=toys-and-games&qid=1244404088&sr=8-1">http://www.amazon.com/Tamiya-America-Inc-Motor-Gearbox/dp/B00061HHQS/ref=sr_1_1?ie=UTF8&amp;s=toys-and-games&amp;qid=1244404088&amp;sr=8-1</a>? Also is this the correct track and gear set: <a rel="nofollow" href="http://www.amazon.com/Tamiya-America-Inc-Track-Wheel/dp/B00061HHRC/ref=pd_sim_t_2">http://www.amazon.com/Tamiya-America-Inc-Track-Wheel/dp/B00061HHRC/ref=pd_sim_t_2</a>? Thanks.<br/>
They are the right parts.
Are you sure? I just looked and that gearbox does not have the 114.7:1 gear ratio. It only has 207:1 or 58:1 ratios. This is the one that has the 114.7:1 ratio: <a rel="nofollow" href="http://www.amazon.com/gp/product/B000C8F802/">Double Gearbox L/R Independ 4-speed</a>. Sorry if I'm being a bit nit picky about this. I just want to make sure i order the right one. Did you see the comment i made on you orangeboard? It might be useful information to update the instructable with. Thanks.<br/>
Here the website site that were I got my gearbox <a rel="nofollow" href="http://www.jaycar.com.au/productView.asp?ID=YG2741&amp;CATID=9&amp;form=CAT&amp;SUBCATID=306.">http://www.jaycar.com.au/productView.asp?ID=YG2741&amp;CATID=9&amp;form=CAT&amp;SUBCATID=306.</a> Sorry for the confusion but the ratio I did use is 114.7:1 as long it got that ratio, your good. That link you supply (the second time) look like the same box that came with my gearbox. Sorry I didn't read the orange board properly. Hope you have good luck with your project. I will update this ible this weekend and list where I got my parts. :) <br/>
Yeah I was actually starting to wonder myself if the two were the same. It would be good to list where to get parts just to avoid any confusion. This is a really cool idea. Have you looked into using rechargeable batteries like they use in real RC vehicles (not that this isn't a real RC, this thing is better than store bough ones any day)?
What is the difference between the Mk.1 and the Mk.2 platforms?
Not much part from the way I setup the road wheels.
coolio. I'll try to build this soon.
why dit you take the control bord apart?
I could use this to drop smoke bombs in my neighbors garden this thing looks awesome.
does one motor drive the gears and the other allow for the changing of directions?
Nope. One motor drives one side of the tank track and the other motor drives the other tank track. So having two motor allow the tank to turn via turn off one motor to turn in a direction.
blam it boys
Sooo cool! I want one too!
