| Research Abstract |
The objective of this research is the development and application of a highly versatile, small and high performance haptic interface. Specifically, it is the realization of a compact 6-DOF haptic interface device with wide workspace and response bandwidth, the realization of a highly versatile control device with a very simple interface for various computing systems, and the application of this haptic interface device to the space teleoperation. The outcome of this research can be summarized as below.
1. A new analysis model to calculate the stiffness of the parallel structure as a function of the structural parameters was developed. With this model, it became possible to easily predict the variations in the stiffness of the parallel structure due to the changes in the structural parameters. Consequently, it became possible to optimize this haptic interface from the stiffness point of view.
2. The haptic interface with a widely improved stiffness was designed and its prototype was developed. Backed by the above-mentioned analysis model and along with a prototyping experience basis until now, the successful design and prototyping of a haptic interface with largely improved characteristics over the prototypes developed until now was achieved. It is also planned to share the engineering drawings of this new haptic interface prototype on the internet.
3. The space teleoperation is picked up as an application of this haptic interface, and the research is carried out. With this haptic interface, the teleoperation experiment of the Engineering Test Satellite VH (ETS-VII)-based robotic arm was executed and hence the effectiveness of its light weight and wide movement range features was demonstrated. Moreover, a dual-arm robotic system was developed as a ground-based experimental setup for the space teleoperation, and this haptic interface was employed in place of the master device for this system and hence its usefulness was shown.
