Autonomous Security Robot Patrols With Randomized Waypoints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance robots used in security systems have predictable patrol routes that can be easily discovered by individuals, compromising security.
Innovation Solution
A security system that randomizes waypoints for autonomous mobile machines within a facility, transmitting a new random waypoint and surveillance tasks after each task is completed, preventing the storage of a predictable patrol route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surveillance robot uses a stored patrol route with instructions to move around a facility, then the robot can perform systematic surveillance coverage, but the route becomes easily discoverable by individuals watching the robot or by compromising the robot's memory
Solution Approach 1:
The patent applies dynamics by transitioning from a static, pre-stored patrol route to a dynamic, real-time generated route. The surveillance robot receives incremental instructions to move between randomly selected waypoints rather than following a fixed predetermined path. This dynamic route generation ensures that the patrol pattern changes continuously, making it unpredictable to observers and resistant to memory compromise attacks.
Solution Approach 2:
The patent changes the parameter of route predictability by using random waypoint selection instead of fixed sequential navigation. The system generates random waypoints within the facility boundaries and instructs the robot to navigate to these dynamically selected locations. This parameter change transforms the patrol route from a deterministic sequence to a stochastic pattern, enhancing security while maintaining systematic coverage.
2Reliability
If the surveillance robot follows a fixed patrol route, then the coverage area is well-defined and systematic, but security is compromised because the route can be easily discovered or the memory compromised
Solution Approach 1:
The patent introduces an intermediary component - a secure server or control system - that generates and transmits waypoint instructions to the surveillance robot. This intermediary handles the complex random route generation logic separately from the robot itself, simplifying the robot's onboard memory requirements while maintaining security. The intermediary acts as a mediator that provides incremental navigation instructions without requiring the robot to store the complete patrol route.
3Ease of operation
If the robot stores complete patrol route instructions in memory, then navigation is straightforward and systematic, but the memory becomes a security vulnerability that can be compromised to reveal the entire route
Solution Approach 1:
The patent segments the patrol route into discrete, randomly generated waypoints transmitted incrementally to the robot. Instead of storing the complete route as a single continuous path in memory, the system divides navigation into multiple small segments - each representing a transition between adjacent random waypoints. This segmentation reduces the information stored in the robot's memory at any given time, making memory compromise less valuable while maintaining systematic navigation through cumulative waypoint coverage.

AI summary
Systems and methods for randomized autonomous robot security applications may include a security system that generate a patrol area of a facility and select a random waypoint from a plurality of waypoints in the patrol area for an autonomous mobile machine to surveillance. The security system may also select a surveillance task to be performed by the autonomous mobile machine at the random waypoint, and transmit, to the autonomous mobile machine, instructions to visit the random waypoint and perform the surveillance task. When the security system receives, from the autonomous mobile machine, an indication that the autonomous mobile machine has completed the surveillance task at the random waypoint, the security system may transmit a subsequent random waypoint of the plurality of waypoints of the patrol area along with a subsequent surveillance task to be performed at the subsequent random waypoint.
