Have you come across the adder/subtractor drive? Although it make the gear chain slightly more complex - it may mean you can leave out the sensor entirely. The drive has two inputs (A and B), and two outputs - one being A+B, and the other A-B. So if (...) (20 years ago, 10-Jun-04, to lugnet.robotics.rcx.nqc)

(...) It might be theoretically possible to use one RCX sensor port for control of the cybermaster - and using the one motor and one sensor port on the cybermaster. A few multiplexing designs I've seen use switching between passive and active sensor (...) (20 years ago, 10-Jun-04, to lugnet.robotics.cybermaster, lugnet.robotics.rcx)

(...) Sounds good. I use a CyberMaster for the movement part of the robot because it has tachos on each internal motor. I modify the power settings for the motors to keep the robot (reasonably) straight, rather than stop and start them. If you tried (...) (20 years ago, 10-Jun-04, to lugnet.robotics.rcx.nqc)

Hi I saw in the LEGO Mindstorms Web Page that many people made their robots with 2 motors go straight using one rotation sensor on each wheel and stopping the correct motor until both sensors were equal. I got Ultimate Accessory Set as a present (...) (20 years ago, 10-Jun-04, to lugnet.robotics.rcx.nqc)
