AI Technical Summary

Benefits of technology

This patented technology allows for more flexibility than previous designs that only had six or eight degree of movement at one side (legs). It also reduces the size of each motor compared to older robots without this feature. Additionally, its use makes them easier to navigate through complicated terrains such as steps or uneven surfaces while maintaining their stability. Overall, these improvements make robotic feet have better performance over time.

Problems solved by technology

This patented technical problem addressed in these documents relates to improving humanoids' capabilities through various techniques like robotic arms that allow them to move freely without requiring physical contact between people and objects. Additionally, reducing costs associated with purchasing humanois has led to an increasing interest towards developing affordable robot designs that mimick natural environments but require fewer components compared to existing ones.

Abstract

The invention provides a double-foot robot walking mechanism. The double-foot robot walking mechanism comprises a waist mechanism and two leg mechanisms with the same structures, wherein the leg mechanisms are symmetrically arranged and connected to the two sides of the waist mechanism; the leg mechanisms comprise thigh mechanisms and shank mechanisms; the thigh mechanisms are formed by serially connecting Chebyshev mechanisms and pantograph mechanisms arranged from top to bottom; the shank mechanisms consist of two sets of parallelogram mechanisms arranged at the upper parts and the lower parts of the shanks; shank extension driving motors are mounted at the upper parts of the shanks for driving and adjusting the lengths of the shank mechanisms to adjust the gait of the walking mechanism so as to cross over obstacles; the waist mechanism comprises a gear module, a bearing module and a waist bracket; the steering of the leg mechanisms in the walking process is realized through planning the alternate positive-negative rotation of a waist driving motor; and rollers for realizing a wheel type walking mode are arranged on the shank mechanisms. The double-foot robot walking mechanism has such advantages as various functions, reliable structure, simple control and low cost.
