Constant miniaturization and increasingly complex coordination tasks in tools and machinery present challenges for control technology. The Epos P from Maxon Motor represents a programmable positioning controller for brushless and brush DC motors with an output of up to 120 W. This master version allows whole systems to be controlled autonomously with an integrated memory. The CAN field-bus and CANopen protocol represents key technology for successful implementation of complex control tasks using Epos controls.
Application in EOD robots
Using Epos controller with Maxon motors, the company Telerob has developed a remote controlled EOD robot to investigate dangerous areas from a safe distance and diffuse explosive charges. It can be used, for example, in airplanes with a suspected bomb on board.
CAN is used to communicate systematically with the modules. The CANopen protocol was crucial in speeding up the robot’s development in addition to making it simpler and more modular. The axes are largely controlled on a time-independent basis, which means that the field-bus performance meets requirements. The use of field-bus technology allows sub-modules, such as a prehension arm or drives, to be used modularly for other products. It also simplifies the use of mechanical interfaces.
