Dynamics And Steering Of A Vibration-Driven Bristle Bot In A Pipe System, Ian Stewart
All Theses
Soft vibrational robots are robots that incorporate compliant structures into their design and are driven by oscillating actuators. A recent, popular version of a soft vibrational robot is the bristle bot, which uses flexible bristles and a vibration motor to propel itself across surfaces and through pipes. This motion is primarily driven by stick-slip dynamics resulting from asymmetric frictional forces applied at the bristle tips. Depending on the frequency of vibration of the motor, the robot experiences various resonance regions allowing it to maneuver in different directions. Attaching bristles to all sides of the robot and placing it in a …

Autonomous Collision Avoidance, Thomas Stevens, Elliot Carlson, Ian Painter
Mechanical Engineering
A steering controlled, autonomous collision avoidance system has been developed by California Polytechnic State University. This system represents a step in the direction of fully autonomous driving, while allowing the driver to maintain control of the vehicle during normal driving conditions. In the case of an imminent collision, the system removes control of the vehicle from the user and autonomously steers around the obstacles. The final system is able to avoid two static obstacles with a 95% pass rate and one moving obstacle with a 50% pass rate. With full scale, fleet wide, implementation of this system it is expected …
