Tele-robotics - the remote control of robotic systems - can help in many situations; nuclear, space, undersea, and dangerous environments such as fire fighting and rescue. At the moment, it is hampered by the poor quality and quantity of sensory feedback to the human operator and to the supervisory control systems that reduce the workload on the operator. This lack of sensory feedback also affects people who have artificial limbs of have lost the sensory ability in a limb.
This project had the aim of improving two areas of sensory feedback; Textural feedback, which includes the sensations of slip, edge detection, and textural information of objects being manipulated, and Thermal feedback, which includes the thermal conductivity and temperature of an object being manipulated.
To this end a small, portable textural and thermal feedback system was designed and constructed, and system software developed for the microcontroller and PC. The system was tested, both for physical accuracy and speed, and for physiological accuracy of the sensations. In the case of thermal feedback, the system performed well, but in the case of textural feedback, some performance was below that expected.
The system was also used for real-time object material recognition by thermal characteristics, and virtual object sensation generation, producing highly accurate results.
