Technology Robota, being a humanoid doll, stands at 45 cm high. Her arms, legs and head are made from plastic components of a commercially available doll. The motors that drive the arms, legs and the head have each 1 DOF. She can detect and respond to touch through potentiometers to detect passive motion of its limbs and head. Various sensors (emitter/receiver, light detectors, etc,) can also be connected to Robota.
The best feature of Robota is that she can copy and imitate upward movements of the user’s arms and sideways movements of the user’s head when the latter is sitting close to the robot. Thus, the user can ‘play’ imitating and turn-taking games with Robota. Furthermore, machine learning algorithms allow Robota to learn from the user, for example, she can be taught a sequence of actions as well a vocabulary. Some of other robots used in the AuRoRa project are: (1) Mel Robot --> 38 cm long --> 30 cm wide --> 12 cm high --> 8 IR sensors --> 4 wheels (2) Pekee Robot --> Oval-shaped --> 2 motorized wheels --> 15 distance measuring sensors
