That’s right! The Robot Games are returning to the Western Canadian Robotics Society May 15th 2010! What will you be bringing to the competition this year?
With robots, it is always misleading as to the number of choices you have in your design, both electrically and physically. As Brutus has mentioned before, the ATMEL chips on an ARDUINO board are very popular amongst hobbyists as the core of their robot. My personal preference has been the PIC microcontrollers, made by MicroChip. What is your preference?
