Modular six freedom-degree initiative joint type bipod walking robot

Abstract

The invention discloses a modular active joint type biped walking robot with six degrees of freedom. The robot consists essentially of six joint modules and two circular feet. Each joint module has a rotating freedom degree and is driven by a DC servo motor. The joint modules have two types, joint rotating shafts thereof are respectively parallel and vertical to the axis of a joint connecting rod and respectively called as I type or T type. All the modules are sequentially connected in series, and the sequence is as follows: foot-the I type joint-the T type joint-the T type joint-the T type joint-the T type joint-the I type joint- the foot. The rotating shafts of the four T type joints in the middle are parallel to each other, and vertical to the rotating shafts of the I type joints at the two ends. The robot has a plurality of walking models, including twist gait, transverse gait and flip gait. The robot is characterized by few freedom degrees, active walking, simple structure and control, good adaptability to the environment, strong obstacle-climbing capability, low energy consumption and the like. The robot can be widely used for operations such as carrying, detection, disaster relief and the like.

Description

Technical field [0001] The present invention relates to the technical field of robots, in particular to a biped walking robot constructed by a modular method with six degrees of freedom and all joints are active. Background technique [0002] Humanoid robots are the most advanced and cutting-edge embodiment of today's robotics technology development. They have a human-like appearance and imitate humans in terms of structure and walking style. Its structure is complex, often composed of upper body and lower limbs, with legs and hands, and often up to 30 degrees of freedom. The core technology of humanoid robots and the most challenging difficulty is the realization of dynamic balance when walking with two feet. Since the early days of the development of robotics, bipedal walking has been considered one of the most difficult challenges. As early as thirty years before the famous humanoid robots ASIMO, QRIO and HRP-2 appeared, biped walking has always been the focus and difficulty i...
