I actually created this for another project but found several uses for it. For example, you can attach a motor under it and turn it into a salt spreader or use it as personal slave to carry around tools and items. To customize, you can use plexiglass for frames to actually see the motion of the wheels and LEDs for a special effect

I started by making its blueprints and figuring out it's measurements. 

1. Wood
2. Machinery (Jig Saw, Band Saw, Drill)
3. PVC pipes for spacers
4. Windshield Wiper motors for driving
5. Hitec 180 Degree servos
6. Aluminum bars
7. Timing belts from a lexus
8. 18v electric hand drill battery  (for power)

I use EZ-Robot Bluetooth controller to control servos wirelessly but you can use any servo receiver. The controller image shows how I assigned ports and the image after that shows the control buttons. The first command moves the servo to the given position and second command moves the servo back to another position. For example, the track servo is at 35* (stable) when you press the button, it moves to 70* (left) and when you stop pressing the button, it moves to 35*. 

A + X = forward, B + Y = reverse, X + Y = left, A + B = right

p.s. I will soon post a video of the track system in action

realistic video of the track

sorry that you have to see such hideous paint job (it wasn't me who painted it)

very well designed
this is awesome
you should put EL Wire on it to make it look even more awesome
efficient and affordable, i like that
nice job <br> <br>i would love to see this in aluminum
a great affordable project (PVC and Wood)
found the other two threads that relate to this, you did a great job on all three
this would make a great father and son project
great project
above the influence, bye bye arduino
finally, something original
well executed
great idea
the squirrels in the park better watch out
love the idea
great job
I love this. I think the sides should be transparent so you can see the track in motion. Great work! <br>
