Virtual reality technology is potentially applicable to the assessment of assemblability, disassemblability and maintainability of products at an early stage in the design cycle. However, existing VE technology is predominantly vision-based, a key missing feature being the feedback of forces from the process.
The Reactabot is a new robot-like device which responds solely to operator-applied forces. The operator wears a headset connected to a Silicon Graphics workstation and so can "see" the virtual object in front of him/her and can reach out for it. In reality the operator touches a real but surrogate object held in the Reactabot which, from then onwards, mimics the dynamic characteristics of the virtual object and its interaction both with the virtual environment and the operator.
The paper describes the design of the Reactabot, its control and a quantitative evaluation of its performance.
