AI Technical Summary

Technical Problem

Conventional bionic water birds face issues with large gaps between joints due to motor size, limited joint rotation angles, and instability caused by motor weight, leading to potential falling and motor damage from water immersion.

Method used

A bionic animal design utilizing articulation reels, drive wires, and mechanisms to rotate joints, with motors housed within a waterproof torso, enabling flexible neck movements and stable center of gravity, and incorporating distance sensors for obstacle detection.

Benefits of technology

Enables flexible neck movements, stable swimming, and obstacle avoidance while protecting internal components from water, preventing tipping and damage.

Abstract

To provide bionic animals applicable to bionic waterfowl. [Solution] The bionic animal includes a body, a head, a neck, a plurality of articulation reels, a plurality of articulation drive wires, and a plurality of articulation drive mechanisms. The neck includes a base, a plurality of first joints, and second joints. The base is located on the body. The first joints are rotatably connected to each other. The second joints are fixed to the head. The articulation reels are located on the body. The articulation drive wires are wound around the articulation reels and connected to the first and second joints. The articulation drive mechanisms are located on the body and connected to the articulation reels. The articulation drive mechanisms drive the articulation reels to rotate, the articulation reels pull the articulation drive wires, and the articulation drive wires drive the first and second joints to rotate.
