Sign Reading is an activity where a robot uses a camera to recognize text, symbols, or markers in its environment.
Overview
This is a stub page. This activity is not yet implemented in any BRS robot. This page exists to:
- Document the concept for future implementation
- Invite community members to build it
- Provide a starting point for discussion
Real-World Applications
QR code navigation, traffic sign recognition, warehouse rack labeling
Required Capabilities
To perform this activity, a robot needs:
Possible Approaches
QR Code / ArUco Markers
- Use standardized visual markers
- Robust detection algorithms available
- Simplest approach
OCR (Optical Character Recognition)
- Recognize printed text
- Requires significant processing power
- Possibly cloud-based processing
Symbol Recognition
- Detect shapes, colors, patterns
- Train simple classifiers (or use deep learning)
- Balance accuracy vs computational cost
Contributing
Want to implement this activity? Here's how:
- Add the required capabilities to your robot (sensors/actuators)
- Implement the behavior (algorithm) in code
- Test and document your implementation
- Create an Implementation page (e.g.,
YourRobot:Sign Reading Implementation) - Update this page to link to your implementation
- Share on Discord or the Mailing List
