Problems solved by technology

[0003] The existing operation mode of the mechanical arm is mainly operated by the handle or the rocker. The operation command cannot directly control the displacement and speed of the overall movement of the mechanical arm, making it difficult for the operator to complete complex movements without training, and the use flexibility is low. A certain delay, while the position accuracy cannot be guaranteed
Some studies have tried to use data gloves to operate the robotic arm. The data glove can accurately determine the position and posture of the operator's hand, but the existing practical robotic arm can achieve functions such as clamping without imitating hand movements, and it uses a large number of flexible devices. High cost, waste of functions
