Aiming at the disadvantages of the teach pandent in current industrial robot market, such as difficult secondary development, single function and low maintainability, based on the Linux realtime operating system and TCP/IP protocol, the ARM CortexA8 processor with better performance was selected, a new universal teach pandent was developed with the help of embedded tool Qt software. Finally, combined with the controller developed in the laboratory, taking the SRD6540 small sixaxis robot as the research object, a large number of tests were carried out on the functions of the developed teach pandent. The results show that the designed teach pandent not only realizes the control to the robot, but also have friendly human machine interface and strong versatility. It is convenient for later secondary development.
