Soft robots may not be in touch with human feelings, but they are getting better at feeling human touch. Cornell University researchers have created a low-cost method for soft, deformable (可变形的) robots to detect a range of physical interactions, from pats to punches to hugs, without relying on touch at all. Instead, a USB camera located inside the robot captures the shadow movements of hand gestures on the robot’s skin and classifies them with machine-learning software.
The new ShadowSense technology originated as part of an effort to develop inflatable (充气的) robots that could guide people to safety during emergency evacuations. Such a robot would need to be able to communicate with humans in extreme conditions and environments. Imagine a robot physically leading someone down a noisy, smoke-filled corridor by detecting the pressure of the person’s hand.
Rather than installing a large number of contact sensors—which would add weight and complex wiring to the robot, and would be difficult to embed in a deforming skin—the team took a counterintuitive approach. In order to gauge touch, they looked to sight. "By placing a camera inside the robot, we can infer how the person is touching it and what the person’s intent is just by looking at the shadow images, " the researcher, Yuhan Hu, said.
The prototype robot consists of a soft inflatable bladder (囊状物) of nylon skin, under which is a USB camera, which connects to a laptop. The researchers developed a neural-network-based algorithm that uses previously recorded training data to distinguish between six touch gestures—touching with a palm, punching, touching with two hands, hugging, pointing and not touching at all—with an accuracy of 87. 5 to 96%, depending on the lighting. The robot can be programmed to respond to certain touches and gestures, such as rolling away or issuing a message through a loudspeaker. And the robot’s skin has the potential to be turned into an interactive screen. By collecting enough data, a robot could be trained to recognize an even wider vocabulary of interactions, custom-tailored to fit the robot’s task, Hu said.
The robot doesn’t even have to be a robot. ShadowSense technology can be incorporated into other materials, such as balloons, turning them into touch-sensitive devices. In addition to providing a simple solution to a complicated technical challenge, and making robots more user-friendly to boot, ShadowSense offers a comfort that is increasingly rare in these high-tech times: privacy. "If the robot can only see you in the form of your shadow, it can detect what you’re doing without taking high fidelity (精确性) images of your appearance, " Hu said. "That gives you a physical filter and protection, and provides psychological comfort. " [br] What can we learn about soft robots?
选项
A、They can sense different human gestures.
B、They can interact with the touch of hands.
C、They may be sensitive to human emotions.
D、They distinguish shadows with their skins.
答案
A
解析
由题干中的soft robots定位到第一段。细节辨认题。第一段第二句提到,研究人员让柔软、可变形的机器人能够检测一系列的身体互动,从轻拍到重拳击打,再到拥抱。A“它们能感知不同的人类手势”与定位句的陈述一致,故为正确答案。
