(...) I have an E-125 and it will take a little more than a simple H-Bridge. Though I agree, it would be a fine platform for doing robotics. One idea that we've been playing around with at Hangar 18 is swarm computing. What the basic idea is to use (...) (23 years ago, 7-Jan-03, to lugnet.robotics)

Are there predefined constants generated by Bricx or NQC that identifies the Brick (RCX, SCout ...) to wich the generated code is targeted for?

| | H-bridge for PDA?
|
|
Since the end of story there - I wonder if not would be possible to make a lego robot out of a CASIOPEIJA PDA or something the only thing that is needed is some H-bridges for motor driving? (23 years ago, 7-Jan-03, to lugnet.robotics)

(...) Looks like a good start. I'm particularly interested in the details of what the controller sends out to the brick under the different states it can be in (remote vs action mode). (23 years ago, 8-Jan-03, to lugnet.robotics.spybotics)
