HKUST Develops Whole-Body Tactile Robotic Arm EmArm
1 reports · 1 sources
A team at the Hong Kong University of Science and Technology has developed an embodied robotic arm, EmArm, which embeds a flexible optical tactile skin into a rigid skeleton to achieve full-arm tactile perception and adaptive manipulation. The research has been published in Nature Sensors. The tactile skin covers more than 71,000 square millimeters, achieves a spatial resolution of 0.085 millimeters, and maintains tactile perception fidelity of up to 97.9% under five types of environmental interference. In human-robot interaction scenarios, EmArm can recognize five touch behaviors—stroking, pinching, poking, scratching, and hitting—and provide emotional feedback, with recognition accuracy of up to 99.8%. The research team says the system is expected to be further extended to other parts of robots, such as the legs and torso.
