Control system of robot arm based on sEMG

A robot arm control system based on sEMG is presented. Subjects could control robot arm to move up, down, left, right, to push and pull, based on the number of times of sEMG can be counted in time domain. Five subjects were tested to investigate simplicity, accuracy and response time of system. Results showed that, this system was very convenience for subjects to learn how to operate, and furthermore, it also meeted requirements of online operation with high precision and high stability. This study provides a good technical foundation for the development of modular robot arm control system and expresses applying potentials for engineering.
