| | | 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)

| | | | I have another LDraw(n) rover that I posted in the (URL) 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 (...) (25 years ago, 22-Aug-99, to lugnet.robotics)

| | | | (...) 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 (...)

| | | | (...) Yeah... the LDrawn design I came up with is at (URL) I'm very happy with because with two differentials it allows me to track both linear and rotational motion. (25 years ago, 27-Aug-99, to lugnet.robotics)
