The M3S (Multiple-Master, Multiple-Slave) bus is a proposed standard digital communication bus designed to improve access to technical aids by disabled people. It provides a standard interface between input devices and end-effectors, allowing devices from different manufacturers to be linked in the same system. The bus is primarily intended for use on wheelchairs. It is based on an industry-standard protocol-the controller area network (CAN)-and includes additional signal lines to increase safety and integrity.
