I have another LDraw(n) rover that I posted in the
http://www.lugnet.com/cad/dat/models/?n=215 group. Only problem is that it's
kind of top-heavy, and the motors don't gear down much. Still, it's another
design to compare.
Incidentally, has anyone tried to combine a rotation sensor and a touch sensor
on the same input? I've tried programming a sensor task routine to separate
the input signals based on RAW voltage but it's not fast enough to handle
normal movement :(. With two rotation sensors taking up two inputs, I'm not
looking forward to sharing input 3 with two touch sensors and a light sensor.

| (...) Have you tried combining the inputs of the two output motors into a differential? If the inputs are counter-rotating, the net differential body rotation will tell you which side is moving faster, ie: Motor A ------> Differential <--(Reversed (...)

| A/B steering is the simplest possible (and least accurate) steering mechanism. One motor controls each wheel. Similar to the very first robot you build with the Mindstorms CD. No fancy gearing or other machinations. Usually the robot has trouble (...) (25 years ago, 22-Aug-99, to lugnet.robotics)
