Hi all, I'm a lurker/newbie. I'm wanting to build a controlled platform that can move and rotate (sort of like a turtle using LOGO). I'd like this platform to carry my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms (...) (22 years ago, 12-Nov-03, to lugnet.robotics)

(...) One thing you will find, is that you can't drive the motor backwards. Well, it won't go one direction. The direction depends on the wiring.

I'm just curious if there's any harm in connecting motors to active sensor ports... I know you don't get very much voltage/speed/torque, but you do get interesting readings that can be used to detect when the motor stalls. This is potentially a very (...)

(...) One way to do that is to have a rubber-band/spring/shock holding "Output B" in it's starting position. Then, you can use a differential to move both A and B. Going forward, A will be easier to drive, so it will push A to it's limit, then B (...) (22 years ago, 12-Nov-03, to lugnet.technic, lugnet.robotics)
