Within the project GraviMoKo the DFKI RIC develops a demonstrator for testing new electrical drives for exoskeleton systems. The drives have a very low gear ratio which allow a very precise measurement of torques inside the motors. Using these drives should enable us to increase the dynamics of a robotic system like an exoskeleton. Further the DFKI is involved in the planning and execution of experiments inside the Lab and during parabolic flights. We are focusing on motoric movements and the analysis of EMG signals. From the EMG signals with respect to the force muscles generate in normal (earth) gravity and microgravity during parabolic flights or simulated via an exoskeleton.
