WV-1 is a two-wheeled robot on which a pole with weights is installed in an inverted fashion on a pedestal. A feedback system, controlled with ST's ARM Cortex-M3 based 32-bit MCU and the LIS344ALH 3-axis digital acceleration sensor, allows the robot to move while maintaining its balance.
The MCU rapidly computes the angle of robot body incline, angular velocity and other sensor data, enabling the motor to constantly generate optimum torque. Potential applications include postural control functions for humanoids and other devices. Photo: Company, Oct 6, 2008 |
