Tokyo's Olympics may become known as the "Robot Games." Organizers on Friday showed off robots that will be used at the new National Stadium to provide assistance for fans using wheelchairs. Tokyo Olympic official Masaaki Komiya pointed out that Japan is known for its robot technology, and the 2020 Summer Games are a good place to show off. "Robots should not overwhelm people," Komiya, the vice director general to the Tokyo Olympics, told a news conference. "Robots are something that have an amicable relationship with human beings and can work together. That's the kind of robots we envision."

Not to be outdone, Panasonic Corp.-- also a major Olympic sponsor -- showed off its "power assist suit." When worn, the suit offers support to the back and hip area and allows for heavy objects to be lifted with less effort. Panasonic said 20 of the suits will be used at the Olympics and could help guests with their luggage and with other lifting chores.
