Hey guys. I've started a new vehicle series of robots. The first one up will be a sci fi vehicle that has a crane which will be controllable to lift up stuff. Here are the first 3 days of playing around with designing the drive system only. The astronaut shows the scale. This is not the vehicle design, just the drive.
I created an interesting drive and steering system for this one. Its 4 wheel drive, using the ez robot 360 servos. The steering has 4 independent (altho 2 and 2 (L and R) are tied together) steering controls, giving the vehicle tight turns. This demo uses a mobile app to control simple movement. And I have the IO Tiny for now...might double them up.
Only issue i had (not shown here) was trying to use the servo Movement Panel to control speed. Each 360 motor (even tho they are tied to left and right side) seem to have their own speed forward and reverse. I can't really get them to perform the exact same motion. Maybe this is tied somehow to the pots that are installed on each servo.
