A Novel Mobile Robot Design for High Maneuverability

A novel mobile robot design is introduced. To realize high maneuverability such as getting over high steps or no deadlocks when it overturned, a rotational symmetrical structure and a center of gravity shifting mechanism are proposed. The robot is composed of triangle-shaped and straight crawlers connected by two links. The triangle-shaped crawlers can rotate about the axis bar by 360 degrees freely. The robot can get over steps by hanging one of the edges of the triangle-shaped crawlers on an obstacle and rotating the crawlers. In the video, the robot can surmount a 32 cm step which is higher than the robot. The robot system must be useful for information gathering tasks by integrating a sensor network technology into the robot system.
