RoboAxe is an intermediate level robot controller boards based on the PicAxe 20m2 processor with an optional dual DC motor driver and two generous prototyping areas matching the layout of the optional dual 170 point solderless breadboards. RoboAxe was designed to meet the needs of the educational market, making it ideal for use in developing STEM educational courses, FIRST competitions, and could be used as a platform when trying for the new Boy Scouts of America Robotics merit badge. The nature of the resulting design also meets the need of robotics enthusiasts and hobbyists for an affordable intermediate level controller.
