If anyone is at all interested, I have a completed porting the brickOS headers to a set of Pascal units. At present, I have successfully written Pascal versions of essentially all the C and C++ demo files - including TrailerBot. I've also written a (...)

(...) Ahhh. I see your point now. Independent of what the back wheels are doing, you still want a bias in the front wheel itself to go straight rather than spinning in place. Otherwise, all the power could just as easily spin the front wheel in (...) (23 years ago, 30-Oct-02, to lugnet.robotics)

(...) That's *not* entirely obvious. There is a tradeoff between ease of twisting of the turntable and ease of slippage in forward drive. A nice chunky tyre with tons of grip is hard to twist - which makes the robot drive forwards better without (...) (23 years ago, 30-Oct-02, to lugnet.robotics)
