It looks as though the steering wheels have power to them, is the robot 4 wheel drive ?

I love the custom rack. How did you machine it?

4 Wheel Drive, 4 Wheel Steer, CNC Mill

Thats a pretty cool rack+pinion setup. Me likey

[MrForbes]

That is really cool!

Does it take about a second to go from lock-to-lock?

I see a pot on there, what kind of a control system are you using, PID? I saw the video and the steering looks pretty smooth so good job there.

what gear did u use on the outside of the differential and did u use bevel or miter gears and where did u buy them

[robostangs548]

It takes about a half of second to go from one side to the other completely, we are using an x-box 360 controller setup (forward backward on one analog stick = motor control, right left on other analog stick = steering, and when you hold the left trigger down, the right left turns into right left crab steer, rather then the wheels moving opposite for 45 degree turn.... They were bought from HPI, and were created for a 1/4 scale RC baja car... In Northville, we are really into the nitro car thing... it is a fun hobby / fun way to spend small job money :)

Looks good!

I like the use of the RC car diff and axles.
