Abstract

The invention discloses a biped robot based on pneumatic artificial muscles and relates to biped robots. The biped robot based on the pneumatic artificial muscles aims to solve the problems that an existing active robot is driven through a rigid structure, the system structure is complicated, the flexibility is poor, and the energy efficiency of the existing active robot is low. The biped robot based on the pneumatic artificial muscles comprises a left leg, a right leg and a pelvis. The left leg and the right leg each comprise a thigh, a shank, a foot, a hip joint, a knee joint and an ankle joint. The left leg and the right leg are connected through the pelvis. The pelvis is connected with the thighs in a rotary mode through the hip joints. The thighs are connected with the shanks in a rotary mode through the knee joints. The shanks are connected with the feet in a rotary mode through the ankle joints. The iliac muscles, the gluteus maximus, the vastus lateralis muscles, the biceps femoris muscles, the semitendinous muscles and the rectus femoris muscles are arranged on the thighs. The tibialis anterior muscles, the soleus muscles and the gastrocnemius muscles are arranged on the shanks. The upper ends of the iliac muscles and the upper ends of the gluteus maximus are hinged to the pelvis respectivley. The lower ends of the iliac muscles and the lower ends of the gluteus maximus are hinged to the thighs respectively. The upper ends of the vastus lateralis muscles and the upper ends of the biceps femoris muscles are hinged to the thighs respectively. The biped robot based on the pneumatic artificial muscles belongs to the field of humanoid robots.

Description

technical field [0001] The invention relates to a biped robot and belongs to the field of humanoid robots. Background technique [0002] Humanoid biped robot is a research hotspot in the field of robotics. Biped robot can realize stable walking, running, up and down stairs and other actions. Traditional biped robots, ie active robots, usually use rigid motors and reducers as drive elements, and the control and drive systems are very complex, making the energy efficiency of the robot very low. In view of this situation, the present invention adopts the pneumatic artificial muscle as the driving element of the biped robot. Because the pneumatic artificial muscle has the advantages of suppleness, high power / mass ratio, and similar force / length characteristics to human muscles, the robot’s The joints are flexible, which is beneficial to improve the energy efficiency of the robot. Contents of the invention [0003] The invention aims to solve the problems that the existing ac...
