REDUDANCY-BASED OPTIMIZATION APPROACH APPLIED TO ROBOTIC CELL BEHAVIOUR

Robotic architectures offer great capabilities in terms of  workspace and kinematics, but suffer from a lack of stiffness when it comes to high loading. Here, we introduce a set of redundancies, together with kinematic, mechanical and stiffness criteria which enable the placement of the task and optimized path planning.

COLLABORATIVE CROSS AND CARRY MOBILE ROBOTS: THE C3BOTS PROJECT

The C3Bots project aims to design Collaborative Cross and Carry mobile roBots to transport payloads of any shape and mass (removal man task). Several mono-robots catch the payload on the ground and use it as a connecting part in the resulting poly-robot. Two architectures are proposed: (i) C3Bots DGP (Dorsal transport of General Payloads), carries the payload on its top platform and achieves optimal positioning maximizing both stability margin and Force Closure Grasping condition. (ii) C3Bots AT/VLP (All-Terrain/Ventral transport of Long Payloads), carries long payloads between its wheels and performs stable obstacle crossing by re-configuring its shape during an 18-step process.

         

The mono-robots C3Bots DGP surround the payload (a) to maximize the stability margin (b) and the Force Closure Grasping condition (c). A lifting parallelogram mechanism was designed to bring the payload on the mono-robot top platform (d). CAD view of four mono-robots carrying a box (e).

 

Examples of “removal-man task” solved by one operator or several co-manipulating operators, on smooth grounds/slopes/obstacles, for standard or long payloads
