Fig. 7From: A study on a robot arm driven by three-dimensional trajectories predicted from non-invasive neural signalsTPE of MEG and EEG. a The distance between the target sphere and adaptive robot gripper was 30 cm. The radius of the TPE is the average distance between the target sphere and adaptive robot gripper at the closest position. b Miniaturized drawing of the real BMI system. Lengths are proportional to the actual size. TPE terminal point errorBack to article page
