NEC has recently offered the R100 personal companion robot . It is about 45 cm. BUT, it can talk and listen and can move around with its wheels and can also see with its eyes. NEC has built a small personal robot which they call PaPeRo. Here is the press release .
PaPeRo details are here .
PaPeRo can understand 650 phrases and can speak 3000. Last year they hooked up with Hasbro Toys to have them produce the baby-bot. It can be operated with a RC joy-stick control system. It has up to 60 servos and many movements. Perhaps they will do an adult android next.
