Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If man-made legged robots are designed to traverse obstacles and perform complex maneuvers, then their adaptability and versatility improve, but their power consumption increases significantly
Solution Approach 1:
The patent utilizes the animal's own muscles and sensory systems to perform locomotion and obstacle traversal without requiring complex mechanical actuation systems. The animal naturally performs complex maneuvers and adapts to terrain using its biological systems, eliminating the need for high-power motors and complex control mechanisms that would otherwise be required in a purely mechanical robot.
Solution Approach 2:
The patent replaces mechanical actuation systems with biological systems. Instead of using motors, gears, and mechanical actuators to move the robot's legs, the system uses an animal's muscular system. This substitution dramatically reduces power consumption while maintaining or improving the ability to traverse obstacles and perform complex maneuvers.
2Ease of operation
If man-made legged robots are equipped with complex control systems to improve controllability, then their ease of operation improves, but their device complexity increases
Solution Approach 1:
The animal's nervous system and sensory organs naturally perform the complex control functions that would otherwise require sophisticated electronic control systems. The animal autonomously processes sensory information from its environment and adjusts its movements accordingly, eliminating the need for complex onboard computers, sensors, and control algorithms.
Solution Approach 2:
The animal's biological systems perform multiple functions simultaneously - sensory detection, processing, decision-making, and actuation - all within a single integrated system. This multi-functionality reduces the overall system complexity compared to a mechanical robot that would require separate subsystems for each function.
3Ease of operation
If man-made small-legged robots are designed to be portable and inconspicuous, then their ease of operation improves for certain tasks, but their power consumption becomes a critical limitation
Solution Approach 1:
The animal's metabolic systems provide continuous power for locomotion without requiring large batteries or power sources that would compromise portability. The animal naturally manages its energy requirements through biological processes, allowing the robot to remain highly portable while maintaining operational capability.
Solution Approach 2:
Replacing mechanical power transmission systems with biological muscular systems eliminates the need for heavy batteries, motors, and power management electronics. This substitution enables the robot to be extremely portable while maintaining the ability to perform complex maneuvers.

AI summary
A method of controlling a movement of a hybrid robot including a locomotion stimulation device carried by an animal includes monitoring, via a positioning component the locomotion stimulation device, a position and an orientation of the hybrid robot; providing, via a stimulator of the locomotion stimulation device, a stimulus to the animal based on an angular difference between the orientation with respect to a direct path from the position to a predetermined destination to control the movement of the hybrid robot; monitoring, via the positioning component, one or a combination of a displacement, a velocity or an acceleration of the hybrid robot in response to the stimulus; ceasing provision of the stimulus to the animal in response to the one or the combination of the displacement, the velocity or the acceleration being below a corresponding pre-defined minimum so as to allow the animal to roam freely.
