Synchronous three dimensional actuator

Humanoid robotics is a class of robotics that involves the development of manipulators that aim to mimic human behavior, appearance, and capability. Humanoid robots are largely intended to assist and replace human beings in carrying out critical task operations.

The development of the humanoid robot today is largely focused on artificial intelligence systems and the embodiment of natural morphological intelligence. For a long time, very little progress has been made in improving the mechanical actuators that can significantly aid structural members in exhibiting natural movement more closely. The existing approach to mimic human-like motion either involves extensive use of motors alone, or a string-based actuation system coupled with motors.

The motions achieved under such arrangements are discontinuous and require lengthier codes to be executed at the back end. Principally, rotary motors are a bi-axial actuation system (a member mounted on the shaft of the motor is subjected to displacements in X and Y directions only), hence a setup comprising of three motors in three unique Cartesian coordinate directions are necessary to execute a 3D movement. The approach, to base humanoid robot designs on only the existing actuation methods, always requires improvisation.

Current status: a demonstration prototype has been developed and further work requires the development of firmware and algorithms to create a high-level user GUI.
