The upgraded processor makes the support more reliable, and a new generation of hydraulic turning device can make the user's gait more natural and comfortable. PLG with computer legs has most responsive to the processor, it can per 1000 times of data acquisition, and can make corresponding response within 10 milliseconds, so it can be according to the change of user's gait synchronous response. Adjustable support and resistance, users by manually adjusting the support resistance can complete from the cycling of the knee joint without resistance free rotation state, suitable for the transformation of work on the assembly line of resistance, the largest state in.
