چکیده

We examine a dual-quaternion formulation for expressing the relative rigid body motion between two objects when incidence constraints are to be observed. The incidences are between points, lines and planes, of the two parts. Both parametric and implicit representations are investigated. Several examples illustrate the techniques .

Optimal Load of Flexible Joint Mobile Robots Stability Approach

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

Planning Motion Compliant to Complex Contact States

Many robotic tasks require compliant motion, but planning such motion poses special challenges not present in collision-free motion planning. One challenge is how to achieve exactness, i.e., how to make sure that a planned path exactly compliant to a desired contact state, especially when the con guration manifold of such a contact state is hard to describe analytically due to high geometrical ...

Constraint Compliant Control for a Redundant Manipulator in a Cluttered Environment

In this paper, we present an iterative kinematics control law for redundant manipulators overcoming some usual problems associated to cluttered environments (constraints violations, oscillations, environment dilatation). The Constraints Compliant Control approach relies on a passive avoidance scheme (no motion generation for constraints avoidance) on a limited number of constraints selected fro...

A virtual reality interface for the design of compliant mechanisms

The objective of this research is to develop an immersive interface and a design algorithm to facilitate the synthesis of compliant mechanisms from a user-centered design perspective. Compliant mechanisms are mechanical devices which produce motion or force through deflection or flexibility of their parts. Using the constraint-based method of design, the design process relies on the designer to...
