1.  Vision for the Human Safe Robot Project

New classes of robots are being designed to interact with humans: helper robots, cobots, and exoskeletons are fast becoming commercialized. The old methods of keeping humans and robots completely separated to ensure safety are antiquated and prevents potential productivity improvements through human-robot teams. In order to achieve the goal pervasive robots, the issue of safety must be addressed. This body of work seeks to investigate and implement design methodologies for the development of safe robotic platforms.

Impact Absorbing Capacitive Skin Sensors for Collision Detection and Impact Mitigation

Without sensors, robots are unable to detect and respond to external stimuli. BDML has developed robust, low cost capacitive skin sensors that combine sensing as well as peak force reduction capabilities. Current work includes interfacing the prototype skin with robotic platforms, such as Honda's Asimo and the Stanford Safety Robot manipulator, and developing post collision behaviors to minimize injury.

Robot Collision Testing

Collision testing allows efficacy verification of robot skin as a sensor array as well as impact mitigation system. Testing is currently done using an AdeptOne robot platform; future plans include impact testing using different robot platforms as they become available.

Robot Design Tools and Injury Modelling

Numerous design tradeoffs are necessary before anything is built. Research at the BDML seeks to provide designers with tools that help translate robot design parameters into their effect on injury. This work combines tissue modelling with robot hardware design.
