Rolling Robot Arm Deployment for Obstacle Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling robots for military and civil security applications are heavy, slow, and lack the ability to quickly navigate through close combat situations or overcome obstacles, limiting their effectiveness in high-risk environments.
Innovation Solution
A rolling robot designed to move parallel to two planes, equipped with a deployable arm that can protrude through either plane for obstacle clearance and payload deployment, featuring a motorized gearbox for efficient arm operation and a waterproof, fire-resistant structure for outdoor use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the robot is made heavy-duty with robust structure for obstacle clearance, then it can overcome obstacles and stones, but it becomes too heavy to be carried by hand by a soldier
Solution Approach 1:
The robot body is divided into two functional halves that can move independently relative to each other. Each half can rotate 180 degrees to become the leading side, allowing the robot to clear obstacles by lifting one side over stones or curbs without requiring excessive overall weight or strength
Solution Approach 2:
The robot employs dynamic movement where the body halves can rotate and reposition during operation. This dynamic capability allows the robot to adapt its configuration for obstacle clearance rather than relying on static heavy-duty construction, maintaining lightweight design while achieving robust obstacle overcoming capability
2Speed
If the robot is designed for high speed movement in close combat, then it can engage quickly, but it lacks the ability to free itself if stuck on obstacles
Solution Approach 1:
The robot's body halves can dynamically rotate and reposition relative to each other, enabling the robot to recover from stuck positions on obstacles while maintaining high-speed movement capability. The dynamic configuration change allows the robot to adapt to different terrain conditions without sacrificing speed
Solution Approach 2:
The same dynamic body mechanism serves multiple functions: it enables high-speed movement for close combat engagement and simultaneously provides obstacle recovery capability when the robot becomes stuck, making the system universally capable without requiring separate specialized mechanisms
3Device complexity
If the robot has a fixed camera orientation, then the structure is simple, but the camera image is not properly oriented when the robot lands on different sides
Solution Approach 1:
The camera system is integrated with the dynamic body mechanism, allowing it to automatically orient correctly regardless of which side the robot lands on. The same camera structure serves both simple imaging and adaptive orientation functions through its connection to the rotating body halves

AI summary
The invention relates to a rolling robot (1000) comprising movement means (1010, 1020) that allow it to move parallel to a first movement plane (P1) or alternatively parallel to a second movement plane (P2), and also a body (1030), the volume of which is confined between the two movement planes (P1, P2), characterized in that it also comprises an arm (1040) that is mounted on the body and assumes either a stowed configuration (R) in which it is confined between the two movement planes, or a first deployed configuration (D1) in which it projects through the first movement plane (P1), or a second deployed configuration (D2) in which it projects through the second movement plane (P2).
