If you are in Nagoya, this seems to be worth a visit. The German robotlab has two robot art installations at the ROBOTHINK area of the museum. There is a webcam showing the robot installation in action.
We reported about the robot museum in Nagoya the first time in August. The museum will also feature a large robot store dubbed Robot Mirai Department.
