Fig. 3From: Blending of brain-machine interface and vision-guided autonomous robotics improves neuroprosthetic arm performance during graspingTarget positions for the multiple object task. The 7.5 cm target cubes filled the squares in the diagram and were separated by 10 cm. For a single trial, the cubes were placed at 2 positions connected by dashed lines, and the subject was instructed to pick up 1 of the 2 cubes. The position numbers correspond to the target numbers in Table 2. The cube in Fig. 2b is at the same point on the table as the intersection of the dashed lines here. The “Cameras” box and hand position arrow indicate the location of those components of the robot at the start of the trialBack to article page
