Distributed control of hexapod wall climbing robot implementing Controller Area Network (CAN)
Pages 66 - 78
Abstract
Service robots have been used in tasks that require navigation of horizontal or near horizontal surfaces. Some applications require service robots that are capable of moving along a vertical plane e.g., wall painting, window washing, non-destructive testing (NDT), surveillance, etc. The controller of a wall climbing robot that has many actuators and many sensors is difficult to design because of safety issues. If a central controller is used, a failure in one part of the system can result in a failure of the complete system. This can result in the robot's safety mechanisms failing and the robot falling from the wall. This paper describes the design of a wall climbing robot that implements many actuators and sensors; the hexapod wall climbing robot. Controller Area Network (CAN) is implemented as a distributed controller of such a robot. The distributed controller is described in detail and its performance analysed.
