In this paper, the flexion-extension angles of the three rotating joints of the HF of a sample of 5 participants and of an AF belonging to a mechanical hand-forearm system designed based on the average anthropometric data of the human sample, are measured and analyzed by using the Biometrics data acquisition and processing system and SIMIMotion software. The average cycles of the flexion-extension angles of the three finger joints are obtained for each experimental test performed by each participant and by the AF belonging to the hand-forearm mechanical system. A comparison is made between these cycles. Obtain and compare the phase plans corresponding to each joint of the human and AFs.
