Your portable fitness coach”

　　The inspiration for the development of this robot suit came from an idea of ​​project leader Lieberman. Dream . In dreams, with the help of a machine, some people with limited mobility can express their inner feelings with movements, and people who have never received art training can paint with a brush. After waking up from the dream, Lieberman immediately began to conduct relevant research.

　　This system uses a high-precision motion capture system to record the movements of the coach and the student respectively, then uses specially developed software to compare the movement data of the two, and transmits feedback signals to the robot suit. Braking patches on the suit oscillate according to the wrong degree of movement of the student's joints, creating a force field in the correct areas. The braking patch can also oscillate in clockwise or counterclockwise directions, prompting students to make correct rotational movements.

　　Since people come in different sizes, the system first spends 10 minutes learning the length of a first-time user's limbs and the position of their joints, and comparing it with the coach's body shape. After recording the coach's actions, the motion data will be stored and can be played back repeatedly at different speeds. In the arm movement test, the researchers found that the robot suit could increase learning efficiency by 23% and reduce errors by 27%. Next, they will create a full-body robotic suit and test more complex movements, such as golf swings.

　　The researchers say the system can teach students very precise movements, making it particularly suitable for coaches who are highly skilled in sports but are not good at teaching. Even a blind person who cannot see the instructor's movements can master the precise movements. In addition, suffering from nerve Injured people can use it for rehabilitation training. Researchers are developing new systems to monitor body posture to prevent back pain and other discomfort caused by poor posture. Those who already suffer from body pain can use it to adjust their posture and relieve pain.
