LCP2138 controlled inertial robot

This project represents a one-wheeled rolling robot that runs by using inertia moment. It has two actuators – driving and steering. Robot is also capable to perform reconnaissance and cooperative tasks. Mechanics is pretty simple – inertial driving force is created by attaching a mass to DC electric motor. Inertial allows not only drive but also jump over obstacles if necessary. Steering is provided by using servo motor which actually tilts axis of rotation. Robot is controlled by LPC2138 Arm microcontroller which is a part of Keil MCB2130 evaluation board. Microcontroller as usually generates PWM waveform to drive motors. Using an ARM microcontroller there are lots of room left for improvements like adding additional sensors like gyros, accelerometers or other intelligence. Continue reading
