# Sensor Mounting First Pass

Plan sensor field of view, vibration, cable strain, and calibration access before printing brackets.

## Outcome
Mount a sensor so it can produce useful readings after the robot moves.

## Safe first step
Write what the sensor must see before designing the bracket.

## Ladder steps
### 1. Define measurement target
Learn to define measurement target as one discrete move in the project path.

Check: You can explain or demonstrate: define measurement target.

### 2. Check field of view
Learn to check field of view as one discrete move in the project path.

Check: You can explain or demonstrate: check field of view.

### 3. Plan cable strain relief
Learn to plan cable strain relief as one discrete move in the project path.

Check: You can explain or demonstrate: plan cable strain relief.

### 4. Leave calibration access
Learn to leave calibration access as one discrete move in the project path.

Check: You can explain or demonstrate: leave calibration access.

## Examples

## Common traps
- Printing a final mount before testing position.
- Blocking the sensor with the robot frame.
- Ignoring vibration.

## Practice task
Create a small practice case for sensor mounting first pass and write what each step proves before moving to the next one.
