Starting at 2:23, the video shows the “Please Touch the Robot” demo shaking hands, giving out a business card, and then doing high-fives and a fist-bump. You can see Joe Romano, GRASP PhD student under Dr. Katherine Kuchenbecker, at the front left coaching the participant, since the PR2 we were given to use was mute (no voice).
