چکیده

Virtual Prototyping with haptic feedback offers great benefits in the development process of actuated systems. We present a generic control scheme for the haptic rendering of actuated mechanisms, introducing the active admittance. It extends the conventional admittance control by modeling the actuation and the movable parts of the mechanism separately. This allows for an efficient iterative design and evaluation of an actuated mechanism and its single elements. The practicability of active admittance control is demonstrated by haptically rendering a car door with two actuated degrees-of-freedom.

Haptic Rendering for Under-Actuated 6/3-DOF Haptic Devices

Under-actuated 6/3-DOF haptic devices are mostly used for simple 3-DOF point-based haptic interaction because of missing torque feedback. In this work, we present a system involving sensory substitution and pseudo-haptic feedback that effectively simulate torque feedback using visuo-tactile cues. The proposed system was implemented into a 6DOF haptic rendering algorithm and tested on an under-a...

Adaptive Control for Improved Transparency in Haptic Interaction with Virtual Environments ADAPTIVE CONTROL FOR IMPROVED TRANSPARENCY IN HAPTIC INTERACTION WITH VIRTUAL ENVIRONMENTS

Impedance-type haptic devices are being developed for applications requiring high output forces and large workspaces. The natural dynamics of such haptic interfaces can be significant enough to interfere with the user’s perception of the virtual environment both in free motion and in contact. In such cases, the haptic control algorithm must be able to reduce /alter the apparent dynamics of the ...

Dynamic Trot-Walking with the Hydraulic Quadruped Robot - HyQ: Analytical Trajectory Generation and Active Compliance Control

This paper presents a trajectory generator and an active compliance control scheme, unified in a framework to synthesize dynamic, feasible and compliant trot-walking locomotion cycles for a stiff-by-nature hydraulically actuated quadruped robot. At the outset, a CoP-based trajectory generator that is constructed using an analytical solution is implemented to obtain feasible and dynamically bala...
