(...) Especially when they have to turn in opposite directions, as in the case of a standard differential drive robot (with one motor driving the left and the other the right side of the robot)! This is because a motor is always more efficient (...) (25 years ago, 12-Dec-00, to lugnet.robotics)

You could use the 6-Leg Walker "Mushi Mushi 7" at (URL) in the "Master Builder Tutorial" as the platform for experimentation. I thought the design was real good, ie, symmetrical and with no extra parts used. My only reservation was that 'turning' (...) (25 years ago, 12-Dec-00, to lugnet.robotics)

Bob Fay's suggestion is a good one, here's another option: Drive both sides with a single motor via a differential, add a rack + pinion steering to the front, or, if you have a second differential, create a mixing differential for a skid-steered (...) (25 years ago, 12-Dec-00, to lugnet.robotics)

(...) As lots of other people have said - you really need rotation sensors. If you don't have one - then a line-follower is an option (as other people have also suggested)...or I *suppose* you could put a bright light at either end of your 15 foot (...) (25 years ago, 12-Dec-00, to lugnet.robotics)
