Development of a dexterous cable driven spine mechanism for humanoid robots

2009 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2009
In order to achieve more vivid human-like motion, a 3-DOF spine mechanism is developed. Two degrees of freedom (pitch and roll) are driven by three cables and the other one (yaw) is driven by gear and pulley. The mechanism is light-weighted and is capable of sustaining heavy load.

Optimal Design of a Cable-Driven Parallel Mechanism for Lunar Takeoff Simulation

2017
The technology of taking off from the lunar is of great importance for the returning of spacecraft from lunar. To verify the stability of spacecraft when taking off lunar, the force state of the spacecraft needs to be simulated accurately. Traditional simulation mechanisms are unable to meet the simulation requirements of lunar takeoff.
