Abstract : This study aims at developing efficient humanoid robot controllers for locomotion. The originality of the work stayed in the two-step development of the research. First, simulation helped at designing efficient controllers. Those latter were afterwards implemented to the real hardware.
The design of humanoid robot controllers is a complex task, which is difficult to directly perform on such robots for several reasons:
humanoid robots are expensive;
(they are usually shared by a huge team;
it is not straightforward to have access to all the robot and
direct controllers implementation can damage the robot (while being
potentially dangerous for the operator);
bipedal stability is difficult to maintain;
parameters tuning/optimization is usually not possible on the real
For all these reasons, the design of these robot controllers can benefit from being first performed in simulation, with the purpose to port them later to the real hardware.
Very fast simulators of humanoid robots were implemented taking advantage of the symbolic approach of Robotran. Thanks to the simulators, controllers were designed to obtain bio-inspired locomotion and gaze stabilization algorithms on different humanoid robots. For instance, regarding the design of the bio-inspired gaits, the related controllers recruited many unknown parameters, which were tuned during extensive optimization processes using the Robotran simulator.
