Thank you for viewing! Recommended radio-controlled car for children Robosapien Blue is a humanoid robot approximately 35cm tall, designed by NASA scientists. It is operated using the included controller and Bluetooth. Various actions are possible with the controller, such as walking forward and backward, left and right, raising and lowering arms, opening and closing hands, dancing, and speaking (in a language I don't understand). You can also input actions in program mode to make it move. I played with it for a while after purchasing it, but it has been stored away for the past few years. There is some yellowing and deterioration of the body. Batteries required: Body: 4 x D batteries Transmitter: 3 x AAA batteries Includes: - Body - Controller Although there is no instruction manual, you can view it by searching online. There is a problem with the leg movement, but the arms work fine. Price negotiation is possible.
