Toyota has shown a futuristic-looking single-seat vehicle called i-swing at various events. The automaker has also shown humanoids that can
walk and play a trumpet. Seven Sony researchers are temporarily working in Toyota's robot research unit to help relay the technology to Toyota, says Toyota spokeswoman Kayo Doi.
Toyota is also introducing "TPR-Robina"--a femalelike robot-on-wheels--as a guide at its showroom at headquarters. It can dodge obstacles, sign its name, carry on simple conversations in Japanese and deliver preprogrammed information in an electronic voice.
