Robots are widely utilized in the industry due to their reliable, fast, and precise motions. However, the time delay is ubiquitous in physical systems and engineering applications, including telesurgery and space robotics. It is worth mentioning that a delay in a control loop is an important cause of instability. This motivation led us to examine the effect of input-delay in 7-DOF Baxter and design time delay compensator. First, coupled nonlinear dynamic equations of Baxter were derived using the Lagrangian method, and we verified our model experimentally. Then, we designed a nonlinear predictor-based controller for Baxter. Finally, results are experimentally implemented, and performance of controllers with/without the compensator are compared.
