Alter 3
Alter 3 is an advanced humanoid robot engineered for exploring artificial life, expression, and human-robot interaction through dynamic, autonomous movements. Featuring 43 pneumatic actuators, it generates spontaneous gestures, facial expressions, and simulated locomotion like walking or running without bipedal mobility. Integrated with GPT-4 for interpreting verbal instructions into physical actions, it mimics human behaviors, emotions, and even non-human entities such as ghosts or animals. Equipped with eye cameras for visual learning and a vocal mouth for sound production, Alter 3 excels in artistic performances, including orchestra conducting and opera participation. Its exposed mechanical structure emphasizes minimalism, using central pattern generators and neural networks for unpredictable, evolving interactions that challenge perceptions of life and creativity in robotics.
