NEC developed a smaller version of their PaPeRo robot dubbed PaPeRo-mini.

NEC introduced the conversational robot PaPeRo back in 2004. The new smaller version features also speech recognition and speech synthesis as the large PaPeRo.

PaPeRo measures 385x248x245mm. The new PaPeRo-mini has measurements of 250×170x179mm.

NEC's aim with the PaPeRo-mini was to miniaturize the conversation module. PaPeRo is still a research project and not yet ready for commercial release.
NEC will introduce the PaPeRo-mini at the robotics ROBOMEC 2007 conference in Japan (May 10th to the 12th).
