AI Technical Summary

Technical Problem

Existing robot technologies are limited in their ability to generate diverse and dynamic movements, particularly in biped robots, which rely on repetitive and rotational motions rather than explosive and adaptive actions.

Method used

The use of reciprocating motion to generate forces for controlling joint movements in robots, including explosive motions, by converting these forces into rotational motion through controlled combustion systems.

Benefits of technology

This approach enables robots to perform a wider range of actions, including explosive movements like jumping and running, by harnessing the power of reciprocating motion and controlled combustion, thereby enhancing their mobility and versatility.

Abstract

To provide an actuator for a riding bipedal robot.SOLUTION: A device is attached that controls the torque of paired cylinders in one explosive combustion and a speed at which the cylinders move in and out, and reciprocating motion is used as output without being converted into rotational motion. Since explosive force is outputted, it is possible to perform instantaneous movements such as jumping and running.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention is an actuator for a ride-on bipedal robot. [Background technology]

[0002] The reciprocating motion is used as it is for output without being converted into rotational motion. It outputs explosive power, enabling quick movements such as jumping and running. Summary of the Invention [Problem to be solved by the invention]

[0003] The problem to be solved is to completely revamp the movements of a robot that has never seemed to improve. [Means for solving the problem]

[0004] The movement of the robot's joints is controlled using power obtained from reciprocating motion rather than rotational motion, and explosive motion is also included. Effect of the Invention

[0005] By reconsidering reciprocating motion, the industry will boom with research into explosive combustion, fluid fuels, and the development of systems to control combustion. [Brief description of the drawings]

[0006] [Figure 1] 1 is an explanatory diagram showing the structure and operation of a linear engine. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] A device (mechanical, electrical, or a combination of both) is installed to control the torque of the paired cylinders and the speed at which the cylinders move in and out in a single explosive combustion, and a combustion mixture made from liquid fuel is flowed into the combustion chamber, causing the cylinders to move in and out with explosive combustion. EXAMPLES

[0008] This product is used in pairs at each joint to generate various movement movements. [Industrial Applicability]

[0009] Using a prototype (approximately 3 meters) for technical verification, we will collect data and create the foundation for a ride-on robot. At the same time, we will be able to prepare an environment in which the ride-on robot can exist. [Explanation of symbols]
