Tight cable structure for e.g. haptic interface, has displacement unit displacing mobile member with respect to platform that is suspended inside framework by suspension cables, where unit is distinct to winders/unwinders of cables

摘要

#CMT# #/CMT# The structure has a rigid framework, and an element i.e. wrist (2), interacting with an exterior environment and including a platform (20) and a mobile member e.g. handle (16), that pivots about a rotational axis relative to the platform. The platform is suspended inside the framework by suspension cables (6.1-6.8) linked to winders/unwinders, where the structure is fixed to the framework. The platform is moved by winding and unwinding the cables on the winders/unwinders. A displacement unit displaces the mobile member with respect to the platform and is distinct to the winders/unwinders. #CMT#USE : #/CMT# Tight cable structure for a haptic interface and a robot (all claimed) in an immersive environment or in reeducation. #CMT#ADVANTAGE : #/CMT# The configuration of the cable structure conserves qualities of tight cable interfaces in a simple and inexpensive manner, ensures efficient dynamics due to reduced number of mobile components and low visual intrusion, increases workspace in rotation and reduces the amplitude of displacements of the platform so as to reduce the risks of contact between the cables. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed view of a wrist. 2 : Wrist 6.1-6.8 : Suspension cables 14 : Connecting axle 16 : Handle 20 : Platform.
