Abstract
A robotic system is proposed whereby the system comprises drivers which integrate the power switches and communications electronics for communicating over power lines or wirelessly or over another shared communications channel. In a robotic system comprising such drivers, one or more central controllers communicate with at least one actuator driver across a communications channel, wherein the communications channel is subject to interference caused by an actuator, and wherein at least one of the communication and the operation of the actuators is modified in anticipation of interference occurring such that reliable communication can be assured.
Claims17
A robotic system, comprising:
- an actuator;
- an actuator driver configured to drive the actuator;
- and
- at least one central controller configured to communicate with at least one actuator driver, including the actuator driver, across a communications channel, wherein the communications channel is subject to interference caused by the actuator, and wherein the at least one central controller is configured to modify at least one of a communication with the at least one actuator driver and an operation of the actuator prior to the interference occurring to reduce the interference.
A method of communicating in a robotic system subject to interference on at least one communications channel caused by at least one actuator, the method comprising:
- anticipating the interference on the at least one communications channel;
- and
- modifying at least one of a communication with the at least one actuator and an operation of at least one of the at least one actuator prior to the interference occurring to reduce the interference.
