Abstract
Robot manipulators have many applications and their tasks become complicated when they have interaction with their environments and humans. These complicated tasks need complex controllers. Also, the controller’s complexity will be increased when the used robot manipulators are very flexible. The robot in this work is very flexible while its first mode shape frequency is 1.85 Hz and its oscillation amplitude is more than \(10\%\) of its long link length. Hence, this flexibility must be taken into account in the modeling and controlling process. Another challenge appears when this very flexible robot manipulator interacts with an unknown environment. In this work, an adaptive impedance control for the very flexible robot manipulator is designed and implemented. To investigate the controller, a numerical simulation in Matlab is utilized. The results show that the robot using the adaptive controller can interact with different surfaces with high performance.
