The application relates to a low-energy-consumption
hexapod robot based on nonlinear
rope geometric constraints and a foot end
linearization compensation method thereof, and relates to the field of
robot design. In order to solve the problem that the
robot leg makes circular arc motion with the hip joint as the center, resulting in transverse displacement of the foot end and affecting the motion precision of the robot, the
leg mechanism is arranged on both sides of the
fuselage in six pairs and is symmetrically arranged left and right, three leg mechanisms on the same side are sequentially arranged from front to back and are arranged as front legs, middle legs and rear legs, each
leg mechanism comprises a
thigh, a shank and a foot which are sequentially connected, the
thigh is rotatably installed on the
fuselage through a hip joint shaft, the
thigh and the shank are rotatably connected through a
knee joint shaft, and the thigh and the shank form an inverted V shape, and the shank is a telescopic leg; the hip joint driving mechanism can drive the thigh to rotate around the Z axis to control the front and back swing of the thigh; the
knee joint driving mechanism can transmit power in the process of the front and back swing of the thigh, convert the rotary motion of the thigh into the extension and contraction motion of the shank, and correct the motion track of the foot end.
