A vibration-driven locomotor (capsubot) consisting of a rigid housing and an internal body connected to the housing by a spring is considered. The system is driven and controlled by an electromagnetic actuator that provides a force interaction between the housing and the internal body. The housing moves along a line on a horizontal plane with dry friction. The control voltage is applied to the robot in a periodic pulse-width mode, the voltage polarity remaining unchanged. Theoretical analysis predicts that the speed and direction of motion of the robot can be controlled by varying the period or/and the duty cycle of the control signal. An experimental prototype of the robot is built and the experiments are performed. The experiments confirm the theoretical prediction.
