Robotic prosthesis that enhances mobility for the disabledd
There are an estimated 10 million amputees worldwide. However, the reality is that there are many people who need an artificial leg but cannot use it. There are a variety of barriers, such as the lack of functionality of existing prosthetics and the inability to purchase prosthetics because they are too expensive.
In addition, passive prostheses, which are the mainstream of existing prostheses, do not have power and cannot assist human movements, so they often cause inconvenience in daily life. To solve the problems of existing prosthetic legs, BionicM Inc. is developing a robot prosthetic leg that can assist daily movement.
The idea behind this project is to solve the problems of crutches holding hands, wheelchairs and bedridden people, and people who cannot walk naturally, and to provide freedom and pleasure in mobility through the development of artificial legs. By bringing power to the mobility of people with disabilities, we hope to help them become more independent in their daily lives and advance into society.

PROBLEMS WITH EXISTING PROSTHESES
Heavy burden on the body
An artificial leg without power, which is called passive type, puts a heavy burden on the other side of the leg. On the stairs, you can only climb one step at a time using your healthy feet, and when you stand up from a chair, you need to put your weight on your healthy feet and raise your body by tilting your body. People with physical and muscular strength may be able to accept a certain amount of load, but elderly people often cannot support their weight with their healthy legs and end up in wheelchairs or bedridden living.
It is possible to purchase a prosthetic leg with assistance from a welfare system, but this is limited to some countries and there is a limit to the amount of assistance, so the purchase of a functional prosthetic leg is a heavy financial burden on the user. In addition, prostheses require regular maintenance and replacement, and the financial burden is one of the major obstacles to their use.
