IR Sensor Array Requirements
Confirmed requirements
- PCB for a fast line-following robot.
- 16 infrared reflectance sensors.
- Sensors arranged in an arc.
Decisions still needed
- Overall sensing width and arc depth (or arc radius), including which direction the arc faces relative to robot travel.
- Sensor-to-track operating distance.
- Track line width and surface characteristics.
- Available supply voltage and robot controller/interface.
- Target full-array update rate.
- Mechanical envelope and mounting locations.
Current state
Only this requirements note has been created. No sensors have been selected or verified. The project has no components, nets, schematic, or PCB layout. No simulation or design verification has been performed.
Next work
Clarify geometry and operating height first, then choose reflectance sensors and readout architecture, check update-rate and optical-crosstalk requirements, and design the schematic before proceeding to PCB layout.
