|Fig. 1 The full body COMAN Humanoid|
The COMAN humanoid robot, Fig.1, is being developed within the AMARSI European project which aims to achieve a qualitative jump toward rich motor behaviour in robotic systems, rigorously following a systematic approach in which novel mechanical systems with passive compliance, control and learning solutions will be integrated.
The development of COMAN body exploits the use of actuation systems with passive compliance.
The goal is:
- to reduce the distinction between plant and controller that is typical in traditional control engineering to fully exploit complex body properties.
- to simplify perception, control and learning and to explore how compliance can be exploited for safer human robot interaction, reduced energy consumption, simplified control, and faster and more aggressive learning.
CoMan Dynamic Models and simulation files
These files contain the dynamic and kinematic paramters of the robot, linearized mass-inertia, coriolis, gravity matrices about the upright (zero angles) posture. Separate symbolic functions exist for direct dynamics, inverse dynamics, cartesian sensors, and adding external forces. Moreover, all the documentation regarding the conventions, converting the CAD data to Robotran convention and actuator models are provided with the models.
Access to the full dynamic model files can be requested by filling in this form
A basic version of the floating base model can be downloaded here.
This model includes 6 DoF for each leg, 3 DoF for waist and torso, and 4 DoF for each shoulder and arm. The dynamics of the series elastic actuators and also ground reaction forces are modeled. In order to run this simulator, the user should have Matlab and Robotran multibody software installed. Further documentation about the simulator is available inside the workR folder.
