Solution Overview
Problem
There is a need for a robot that can be easily integrated into diverse environments to assist or substitute for humans, particularly in environments that are dangerous or uninhabitable for humans, with a focus on humanoid robots that can perform complex tasks requiring bending and rotation of the torso.
Innovation Solution
A robotic torso design featuring a torso base and a rotatable torso column with multiple movable joints, allowing for complex spatial poses in three-dimensional space, and coupled with humanoid components such as robotic arms and legs, enabling flexible movement and task completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic torso is designed with multiple movable joints and segments to enable complex spatial poses and bending movements, then the robot's adaptability and task performance in diverse environments are improved, but the device complexity and structural configuration become more complicated
Solution Approach 1:
The torso is divided into multiple segments (first torso segment, second torso segment, third torso segment) connected by movable joints, allowing each segment to be independently controlled to achieve complex spatial poses while maintaining modular design
Solution Approach 2:
The torso employs movable joints with multiple degrees of freedom that enable dynamic bending and rotation movements, allowing the robotic torso to adapt to various task requirements and environmental conditions through controlled articulation
2Ease of operation
If the torso column is made rotatable about the reference axis with additional movable joints for bending about nonparallel axes, then the mobility and spatial flexibility are improved, but the mechanical structure and joint configuration become more complex
Solution Approach 1:
The torso column incorporates rotation about the reference axis (one dimension) and bending about two nonparallel axes (additional dimensions), creating three-dimensional mobility that enables the torso to reach complex spatial configurations

AI summary
A robotic torso for a humanoid robot includes a first torso member having an axial axis aligned with a reference axis and a second torso member having at least one mounting portion for at least one humanoid component. The robotic torso includes a series of actuators arranged in a column between the first torso member and the second torso member and coupling the first torso member to the second torso member. Each of the actuators has a rotatable member defining a rotational axis. The rotational axes of each adjacent pair of actuators in the series of actuators are orthogonal to each other.
