Sarcos is still moving ahead with their exoskeleton project. Here's a video that was posted on Live Leak:
At the moment the suit has battery power for about 30 minutes worth of use. In these demonstrations the suit is wired up to a power source. The current suit generates about 20 times the wearer's strength. A software engineer named Rex Jameson was wearing the suit for some of the publicity events. He mentioned that there is a strange delay in the suit's response time to the wearer's actions. Apparently this just takes some getting used to and doesn't hinder performance. He said the learning curve was, "to relax and trust the robot".
