I believe that every single man wants to have a robot that can help make beds and clothes. And a research team near Berkeley has taken a solid step toward this goal: their autonomous robots have realized the function of folding towels.
“Robots have been able to assemble cars a few decades ago, but folding towels are just around the corner.†Development team leader Berkeley’s Ph.D. student in the Department of Electrical Engineering and Computer Science Jeremy Maitin-Shepard and assistant Pieter Abbeel said.
Most of the robots on the automobile assembly line work under the condition that the structural environment is very stable, which can achieve the work precision that is difficult for humans to achieve. However, this equipment is only suitable for repetitive work in a strict environment, but has limited capabilities in other environments.
Although these small things seem to be inconspicuous, it is a real challenge for robots to perceive and manipulate "deformed objects".
“Our work starts with the shape of the towel that some robots can recognize, and the robot will stack the towels according to standard algorithms,†Maitin-Shepard said.
But the difficulty is that when the robot picks up one of a bunch of towels, it can't guarantee that the shape of the towel is identifiable. It must first change the shape of the towel to something that it can recognize. This is because existing image recognition techniques are more directed to rigid objects. Berkeley's researchers must determine the actual shape of the towel based on the image of the towel and the pattern on it. Solving this problem will help the robot to stack the towels, which is a breakthrough in robotics.
The team's big technological innovation lies in the development of the cloth focus point recognition technology based on the existing computer vision. This is a very effective algorithm because it can rely on some reliable geometric cues to infer the deformed cloth. The actual shape of the face. The method has proven to be very reliable, and Berkeley's research team will release its research report at the International Robotics and Automation Conference in Anchorage in May this year.
