- Having designed and built both hardware and software for a robot for a
- sophomore levelclass for non-technical agriculture majors; I believe that
- FORTH would be a very good language for teaching robotics. The way I
- did it was to use a $2000.00 Acro connected to a PC and the robot.
- I wrote a Basic program that ran on the Acro that ran the pump, read
- the sensors and turned the stepper motor. I wrote a basic like language
- in C that ran on the PC and sent commands to the Acro. The robots
- (20 of the little buggers) have eight sensors (Photo Transistors) a stepper
- motor and a water pump form a battery powered water gun. It finds a
- beaker then finds the other side backs up an fills the beaker. The
- programming took over a month.
-
- If I were to do this project over I would use 68hc11 board from New
- Micros in Dallas that has an onboard FORTH interpreter and let them
- use FORTH it might be a little left handed for the technically deprived
- but no more than any other computer language.The boards cost less
- than $100.00.

- One mans opinion
- Good luck
