Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inspection of underground infrastructure such as municipal wastewater and sewer pipes is labor-intensive, costly, and time-consuming, and existing methods often require human operators to manually control robots for data collection, which can be inefficient and limited in accessing all areas.
Innovation Solution
A head-mounted controller using electroencephalography (EEG) to detect and bin brain activity, allowing users to control pipe inspection robots by varying their thought intensity, with predefined control functions mapped to different brain activity levels, enabling remote operation and autonomous data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control methods are used to operate pipe inspection robots, then operators can directly control robot movements, but the inspection process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical control operations with a neurological control system that detects brain activity patterns. The headset captures neural signals and translates them into robot control commands, substituting the mechanical manual control process with a neuro-based automated control system. This resolves the contradiction by maintaining direct operator control (ease of operation) while significantly reducing the time and labor required (increasing productivity).
Solution Approach 2:
The patent introduces a headset as an intermediary device between the operator's brain and the robot control system. This intermediary captures brain activity, processes it through binning algorithms, and translates it into control signals. The intermediary enables efficient translation of neural intentions into precise robot movements, improving both ease of operation and inspection speed simultaneously.
2Measurement precision
If individual pipe segments are inspected serially by inspection crews, then detailed data can be collected, but the overall inspection process becomes costly and time-consuming
Solution Approach 1:
The patent enables the robot to operate with a high degree of autonomy based on neural commands. The system processes brain activity signals to automatically control navigation, data collection, and movement decisions. This self-service capability allows the robot to perform detailed inspections of multiple pipe segments continuously without requiring repeated manual intervention between segments, maintaining data quality while reducing total inspection time and cost.
3Measurement precision
If brain activity values are accumulated over time to establish threshold levels, then control accuracy improves, but the response time for robot control increases
Solution Approach 1:
The patent implements preliminary binning of brain activity values into predefined categories before threshold comparison. By pre-organizing neural signals into discrete bins representing different control intentions, the system prepares the data structure in advance, enabling faster threshold evaluation and control response. This preliminary organization resolves the contradiction by maintaining accurate detection (through proper binning) while accelerating the control response speed.

AI summary
An embodiment provides a method of controlling a pipe inspection robot, including: detecting, from a headset, brain activity of a user wearing the headset; binning the brain activity of the user into one of a plurality of different bins; the binning comprising accumulating brain activity values for a period of time to establish a brain activity value for the period of time; determining, using the brain activity value, if a threshold level of brain activity has accumulated over the period of time; after the threshold level has been accumulated, identifying a control action to be sent to the pipe inspection robot based on the brain activity value; and controlling the movement of the pipe inspection robot using a control signal associated with the control action. Other embodiments are described and claimed.
