Bionic four-foot robot provided with spinal joint and elastic legs

Abstract

The invention provides a bionic four-foot robot provided with a spinal joint and elastic legs. The robot comprises a front trunk, a rear trunk, the spinal joint and the elastic legs. The front trunk and the rear trunk are connected through the spinal joint, the two ends of the lower portion of each trunk are respectively provided with one elastic leg, the spinal joint comprises end caps, a universal joint, corrugated pipes, hydraulic oil pipes, gear pumps and electromagnetic valves, the upper end cap and the lower end cap are connected in the center through the universal joint, the four corrugated pipes are evenly distributed between the upper end cap and the lower end cap, every two symmetric corrugated pipes are connected together through one hydraulic oil pipe, one gear pump and one electromagnetic valve, the two ends of each trunk are provided with winding reels, the winding reels are connected with output shafts of second steering engines, one end of each steel wire rope is fixed to the corresponding winding reel, and the other end of each steel wire rope is fixed to a corresponding ankle. The robot can move coordinatively and stably, moving characteristics of feline animals can be well simulated, and meanwhile impact of ground to the robot is reduced when the robot falls on the ground.

AI Technical Summary

Benefits of technology

The technical effect of this patented technology is that it provides an improved version for robots called Bionics Quadrupters (BQ). This new design allows them to move smoothly while maintaining their stability even if they are hit from hard surfaces such as rocks or stones during use. Additionally, there're also included flexibility in adding extra parts like stretchable spring elements to improve its ability to absorb shock forces without being damaged due to hitting objects onto the surface over time.

Problems solved by technology

The technical problem addressed in this patented text relates how biological agents called dogs or foxes interact with humans through various mechanisms including movements, environmental factors, and social interactions. These machines require flexibility in both geometry and dynamics when they move around. However current robotic systems lack these feature capabilities due to limitations associated with traditional rigid structures.
