introduction: the birth of remotely operated wearable robots may assist the disabled in rehabilitation exercises in the future. Zhidongxi reported on August 7 that the Graduate School of design for tensile testing machine of Keio University in Tokyo has recently developed a robot backpack called fusion, which is jointly developed by assistant professor Yamen saraij and the University of Tokyo to explore how people can jointly control a person's body through machinery. Although saraij said that this device is not perfect at present, he believes that this device can be used in telemedicine and teaching in the future. 1、 In the figure of robot arm remote control with VR, the two slender robots interacting with saraij are actually remotely controlled by another person. The other controller needs to wear oculus rift VR helmet. Through it, the controller can share vision with saraij and use a special hand-held controller to control the robot arm. Different buttons on oculus rift controller can realize different finger functions: the operator can use one button to move the little finger, middle finger and middle finger of each robot hand at the same time, while the thumb and index finger are controlled by different buttons. Fusion is more like the integration of traditional robots and wearable devices: two flexible robotic arms based on cobalt resources are attached to the user through the backpack, and the camera connected to the backpack provides a good view for the remote operator. Saraiji and colleagues from Keio University and the University of Tokyo jointly developed this robot backpack, which will be exhibited at the siggraph computer graphics and technology interaction conference in Vancouver in August. At present, fusion can not only do simple actions such as shaking hands and high fives, but also help users grasp various objects and assist operators to complete various actions

in fact, this is not the first time that saraiji has developed a robot attached to a human body: he and researchers previously created a set of wearable robotic arms called metalimbs, which can be controlled by the wearer with his feet without the need for other operators. However, it is a completely different concept to control your robot arm with others. Saraiji said, "next, we want to explore what will happen if another person can attach to and control your body in the sense that an engineering plastic can be divided into general engineering plastic and special engineering plastic. Can he help human beings do some more complex work?" 2、 Structure of the robot arm this robot backpack is equipped with a microcomputer responsible for remote data transmission. At the same time, it is also connected with a micro controller, so as to accurately locate the position of the robot arm and calculate how much pressure needs to be exerted on the mechanical joints. Each robot arm is connected to the backpack, and the seven joints on the arm can ensure that it can make various flexible movements. At the same time, there is a head with two cameras connected to the arm, which can provide a clear vision for remote operators. When the operators rotate their heads, the camera will also make corresponding actions. This wearable arm is powered by a 21 pound battery, which can maintain the manipulator for up to one and a half hours

III Application of manipulator saraiji said: "At present, this device is still in the testing stage, but we expect to apply it to many different scenarios in the future. For example, doctors can further understand the patient's injury by touching the patient's damaged body to treat his muscles and correct his movement. In industry, this technology can be used to train factory workers. In these fields, experts can teach skills with mechanical arms or guide workers from cameras Work. " Talking about the reasons for developing this manipulator, Saraiji said, "at present, we have a very common problem when using telecommunication tools for guidance - the disjointed point of view." , which makes it difficult to understand each other in remote collaboration. Previously, there were devices that solved this problem by sharing perspectives, but now we want to go further - sharing a person's body so that others can really attach to the tester and perform a task with him, so we designed this backpack. " Although saraiji claims that the product quality of fusion robot arm can be used to assist patients' paper not only affects consumer satisfaction with rehabilitation treatment, Hermano Igo Krebs, a robotics scientist at the Massachusetts Institute of technology, believes that this project is not applicable to rehabilitation training. But he can imagine that it is very useful in many different situations. For example, assist astronauts in outer space, or an inexperienced medical and nursing staff. Saraiji and his team are constantly improving this machine backpack, hoping to turn this project into a product that truly benefits people. At the upcoming siggraph computer graphics and technology interactive conference in Vancouver, fusion will receive the attention of more experts in the industry, "how to turn this embryonic design into a mature product?" This is the next major challenge for saraiji's team. Original text from: technologyreview, acmsiggraph
