How Humanoid Robot Actuators Connect with a Smart Wire Assembly

This patent describes a specific way to connect two moving parts (actuators) in a humanoid robot using a wire bundle that routes through openings and connects to circuit boards with different numbers of pins.

What it covers

This patent details an advanced wiring assembly for humanoid robots, specifically connecting a first actuator to a second actuator. The first actuator includes a printed circuit board (PCB) with a set of pins and an opening for the wire bundle. The second actuator also has a PCB with its own set of pins. A key feature is that the first PCB's pins are greater in number than the second PCB's pins. The wire bundle has connectors at each end that plug into these PCBs, and the wires are carefully routed through an opening in the first actuator and another opening in its cover. For example, this system could connect a robot's shoulder joint actuator to its elbow joint actuator, ensuring reliable power and data transfer while managing the wiring neatly within the robot's structure.

What it doesn't cover

• —Does not cover wiring assemblies that connect more than two actuators together.
• —Does not cover wiring where the second actuator's PCB has an equal or greater number of pins than the first actuator's PCB.
• —Does not cover wire bundles that are routed externally or through openings not specifically part of the first actuator's body or cover.
• —Does not cover general electrical connections within a robot that do not specifically interconnect two actuators via a dedicated wire bundle and PCB terminals.

The clever bit

The novelty lies in the specific configuration of the wire bundle, the differing pin counts between the two connected actuators' circuit boards, and the precise routing through internal openings. This design likely aims to create a more compact, robust, or efficient connection, potentially simplifying assembly or improving longevity in moving robot parts.

Why it matters

Reliable and compact wiring is crucial for humanoid robots to move smoothly and perform complex tasks without wires snagging or breaking. This type of advanced wiring assembly aims to improve the durability and functionality of robot joints. By carefully designing how wires are routed and connected, it helps reduce wear and tear, making robots more robust for real-world applications.
