Abstract
Automatic electromyography (EMG) electrode selection for robotic devices is disclosed. A plurality of signals from a corresponding plurality of sensors coupled to a skin of a user is received. For each pair of at least some pairs of the plurality of sensors, a sensor pair signature is generated based on differences in signals that are generated by the respective pair of sensors. Each of the sensor pair signatures is compared to a predetermined sensor pair signature to identify a particular pair of sensors. A signal difference between two signals generated by the particular pair of sensors is subsequently utilized to generate a command to drive a motor.
Claims20
A system comprising:
- a sensor assembly comprising a plurality of sensors configured to be coupled to a skin of a user, the plurality of sensors comprising at least three sensors including a plurality of pairs of sensors between each of the at least three sensors and each other of the at least three sensors;
- and
- a processor device coupled to the sensor assembly, the processor device configured to:
- receive a plurality of signals from the plurality of sensors coupled to the skin of the user;
- for each respective pair of sensors of the plurality of pairs of sensors of the plurality of sensors, generate a corresponding sensor pair signature based on differences in signals that are generated by the respective pair of sensors;
- compare each of the sensor pair signatures to a predetermined sensor pair signature to identify a particular pair of sensors of the plurality of pairs of sensors, the predetermined sensor pair signature corresponding to a body part;
- and
- subsequently utilizing a signal difference between two signals generated by the particular pair of sensors to generate a command to drive a motor.
A method comprising:
- receiving a plurality of signals from a corresponding plurality of sensors coupled to a skin of a user;
- comparing the plurality of signals with a predetermined signal signature, the predetermined signal signature corresponding to a body part;
- selecting at least one sensor based on the comparison between the plurality of signals with the predetermined signal signature;
- and
- subsequently utilizing a signal generated by the at least one sensor to generate a command to drive a motor.
