Can anyone point me to a set of plans for a "dual differential" gear train made with Technic parts that allows one LEGO motor to control driving straight and a second motor to control turning? (24 years ago, 7-Apr-01, to lugnet.robotics)

Hi Everyone, I just created a spreadsheet that I think will be useful to many of us. It shows the lengths of possible diagonals in terms of LEGO Units. I created it because I often find myself searching by trial and error for possible diagonal (...) (24 years ago, 7-Apr-01, to lugnet.org.us.smart, lugnet.robotics, lugnet.technic)

hi Lauren, you're quiet right, the inside of the RCX (in touch-sensor mode) is ok, and Ohm's law is also. So the problem lies probably in the sensor used. The cheap resistive pressure sensors are totally non-linear, more expensive sensors are full (...) (24 years ago, 6-Apr-01, to lugnet.robotics)
