Anthropomorphic six-degree-of-freedom robot gravitational equilibrium method

The invention discloses an anthropomorphic six-degree-of-freedom robot gravitational equilibrium method which comprises the following steps: the whole six-degree-of-freedom master robot is arranged in an anthropomorphic arrangement way, and the first joint axis of the six-degree-of-freedom master robot is arranged vertically so as to prevent the first joint from conducting rotary motion around the vertical axis under the action of gravity; the three joint mechanisms of the wrist are in wrist heart arrangement, and through symmetric design or counterweight design, the center of mass of the wrist mechanism is positioned at the wrist heart and intersected with a forearm rod piece at one point; a forearm drive motor moves back to one side of a large arm joint through a parallelogram mechanism; through a large arm drive motor and a counter weight thereof and the forearm drive motor and a counter weight thereof, the whole master position mechanism realizes gravitational equilibrium; and in implementation, firstly t
