Synthesis of Cartesian Stiffness for Robotic Applications
نویسندگان
چکیده
A new, systematic approach to the synthesis of Cartesian sti®ness by springs is presented using screw (spatial vector) algebra. The space of solutions is fully characterized for all sti®nesses realizable by springs. The main result shows that a rank r sti®ness can always be synthesized by r springs. Further, it can also be synthesized by an arbitrarily large number of springs greater than r: Synthesis algorithms are presented and numerical results support the theory.

A Procedure for Experimental Evaluation of Cartesian Stiffness Matrix of Multibody Robotic Systems
In this paper a general procedure is proposed for experimental evaluation of Cartesian Stiffness matrix. The proposed procedure is based on a trilateration technique that is applied for a new tracking system named as Milli-CaTraSys (Milli Cassino Tracking System). A case of study for experimental evaluation of the stiffness matrix is presented in order to show the soundness of the proposed proc...
متن کاملModular Hybrid Robots for Safe Human-Robot Interaction
The paper considers a novel modular and intrinsically safe redundant robotic system with biologically inspired actuators (pneumatic artificial muscles and rubber bellows actuators). Similarly to the biological systems, the stiffness of the internal parallel modules, representing 2 DOF joints in the serial robotic chains, is controlled by co-activation of opposing redundant actuator groups in th...
متن کاملOnline Computation of the Stiffness Matrix in Robotic Structures Using Finite Element Analysis
Finite Element Analysis (FEA) is known to be a highly reliable tool for structural analysis, but this is usually conducted offline. Online use of FEA is usually out of the question because it is highly demanding in terms of computing time. We show in this report how the Cartesian stiffness matrix of robotic structures of a certain class can be computed online with FEA support. The procedure is ...
