Double Eleven is a shopping carnival, a 168.2 billion digital carnival, and the most dazzling moment of Ali's year. It is the most happy moment for consumers but it is also the most tiring time for logistics personnel. Recently, Jingdong’s intimate care for logistics personnel was exposed, but it was praised by netizens. It turned out that Jingdong developed an exoskeleton robot for logistics workers, trying to reduce their lumbar injuries. Logistics personnel need to bend over and take goods frequently, causing a lot of lumbar spondylosis, especially during this period of peak logistics.
The success of a company is not only reflected in the quality of its performance, but also in how much care it pays to its employees. Of course, at the same time, this is the first application of bones at home and abroad in industrial applications.

The origin of the exoskeleton robotRegarding exoskeleton robots, in fact, everyone should be familiar. In Hollywood sci-fi blockbusters such as "The Edge of Tomorrow", the exoskeleton is put on by Tom Cruise and a group of soldiers to make it a super warrior, and the combat power is directly enhanced several times. .
In reality, the development of exoskeleton robots dates back to the 19th century. The famous British illustrator Robert Seymour inspired the steam-powered walking aids in the "Walking By Steam" painted in 1830. The exploration of a concept has also become the prototype of contemporary dynamic exoskeleton technology.
In 1890, a Russian named Nicholas Yagen invented an exoskeleton-like system powered by compressed air. In 1917, American inventors developed a steam-powered exoskeleton.
By 1970, GE designed the Hardman system, which contained more than 30 joints and could lift 1,500 pounds. At the end of the 20th century, with the rapid development of electronic technology, sensor technology and control technology, the exoskeleton system made a historic breakthrough. The US military giant Raytheon Company can help the wearer to lift a few easily by purchasing the XOS exoskeleton system developed by Sarcos. Hundreds of pounds of objects, this system consists of structures, sensors, actuators, controllers, and high-pressure hydraulic systems.
In addition to military use, exoskeleton robots have begun to develop in business. The third-order Jihang, a robotic expert at the University of Tsukuba in Japan, and his colleagues created a company called "Cyberdyne" in 2004, and began to bring the power exoskeleton robots they had developed for ten years to market. They developed an exoskeleton robot called HAL, which is mainly used in the medical field to help people with disabilities and rehabilitation. In addition to HAL, Israel's Rewalk, Japan's HAL, and the US's Ekso are now leaders in this field.

Development of bone robots at home and abroadCompared with these countries, China is in a backward stage in the study of exoskeletons, but the development path is also from military to commercial.
In 2013, the first exoskeleton device developed by the post-doctoral workstation of the Nanjing Military Region General Hospital was officially unveiled. It was defined as the “single weight-bearing auxiliary systemâ€, which is aimed at the military field, focuses on compressing the load, and can quickly synchronize the wearer's movements. Although it is considered to be the most complete exoskeleton device in China, its function is relatively simple, and its load-bearing capacity and design structure still need to be improved.
In addition, the EXOP-1 exoskeleton system designed and developed by the Changzhou Institute of Advanced Chinese Academy of Sciences has officially entered the commissioning phase in 2014. The main body is made of aviation aluminum. It is equipped with 22 sensors, 6 drives and 1 controller, and the cost is about 300,000 yuan. Compared with the military exoskeleton system and the advanced foreign exoskeleton equipment that appeared in Nanjing, EXOP-1 can also reduce the weight of the wearer, but it is relatively bulky and difficult to put into use in a short period of time.
In the commercial market, the domestic two-year period has been exploding. There have been Daai, Scream Technology, and Fu Liye Intelligence have officially released products. Just two days ago, I participated in the new product launch of the robot, and they released the BEAR H1, an exoskeleton robot for patients with hemiplegia.
Of course, these exoskeleton robot companies have also chosen the field of rehabilitation. Mainly the development prospects of rehabilitation robots are more optimistic. According to the prediction of the third-party consulting firm GrandViewResearch, the compound annual growth rate of generalized rehabilitation robots in the next five years is about 37%, of which the compound annual growth rate of rehabilitation robots is 21%, and the compound growth rate of exoskeleton robots is 47%. The average growth rate of medical robots in other categories.
Industrial exoskeleton developmentIt can be seen that the current development at home and abroad is better for rehabilitation robots. On the one hand, the technical threshold in this field is relatively low, and the policy is also relatively supportive. Military robots have a long development cycle, and the exoskeleton is developing in another direction, that is, the industrial field, helping porters and other work burdens.
Panasonic’s awareness in this area was relatively early, and its exoskeleton robot project was announced as early as 2014. In order to allow ordinary workers to easily carry heavy loads of 15 kilograms around, Panasonic made a lightweight version of the exoskeleton bracket. Supported by carbon fiber material in the back, thigh, calf to foot area, coupled with a power motor that can be awakened by a sensor, it can easily help people with a load of 15 kg. Later, Panasonic shared the latest developments in the exoskeleton in a video, introducing three devices that are “exoskeletonâ€, codenamed AWN-03, PLN-01, and Power Loader. The three basic structures are similar and their functions are similar. . When the sensor of the exoskeleton detects that the user bends and lifts the heavy object, the motor provides external power to the limbs of the human body through the transmission device, thereby reducing the burden on the human body.

In the industrial sector, Panasonic has a strong opponent, that is, the Ekso Bionics mentioned above. Ekso Bionics has already made a name for itself in the medical industry, and their lower extremity exoskeleton products allow paraplegic patients to walk on their legs. However, the company's founder and CTO Russ Angold said that mechanical exoskeletons can also find their own sky in the industrial field.
Ekso Bionics has developed an industrial-oriented EksoVest. According to reports, Ekso Bionics is currently working with Ford's factory on a pilot project to allow assemblers to wear this exoskeleton at work. The future may be extended to Ford's plants in Europe and Latin America.
However, now the exoskeleton that can be used in industry, the exoskeleton may be very large and heavy, because the power of the motor, the battery life is not enough. Because of this, we can see in the video released by Liu Qiangdong that Jingdong's exoskeleton robot has a line connected, indicating that it is pneumatically driven.
Of course, this is the first publicly available exoskeleton robot in the industrial field, and the significance is still very significant. Chen Gongxiang, co-founder and CEO of Maibu Robot, said that if there are breakthroughs in the basic components such as motors and batteries in the future, industrial exoskeletons will usher in spring.
