I attended the ICRA conference that was held in St Paul, one of the “twin cities” of Minnesota.
My Professor Jun-ho Oh from KAIST delivered the plenary talk “Development Outline of the Humanoid Robot: HUBO II”, see Fig. 1 below.

Also my lab-mate Dongil (Fig. 2) presented his paper:

The ICRA 2012 Mobile Manipulation Challenge (AKA Sushi Boat Challenge or Yesterday’s Sushi Challenge) was held during the conference, for which teams had to program a PR2 robot to act like a restaurant waiter and make it perform tasks like setting or clearing a table. Video 4 below shows the PR2 robot “Jake” clearing a plate and bowl from the table. I forget which team this was but the robot was on loan from Willow Garage.

There were some other robots on display in the exhibit hall, including the new Robonaut 2 dual-arm robot developed by NASA’s Johnson Space Center and General Motors (Fig. 4).
Fig. 5 shows Robonaut’s hand, which is actuated by tendons (wire cables) that are fed through tubes to linear actuators. The actuating mechanism takes up more space than the fingers and is enclosed within the forearm.
