To keep things simple for the user, you can get rid of the outer set of buttons because those are really only appropriate when you have a joystick-type interface and the latency between the user and the robot isn't so (...)

| Last night I had a new-style 9V motor attached directly to a 40-tooth gear that was turning an 8-tooth gear. There was a fair amount of torque involved, and my motor stalled after a while. Now the thing won't turn unless I really force it. What (...) (19 years ago, 29-Jun-05, to lugnet.technic, lugnet.robotics, FTX)

In most TECHNIC building you're building a gear train to produce lots of power at the expense of speed. (...) (19 years ago, 9-Jul-05, to lugnet.technic, lugnet.robotics, FTX)
