Workflow
Calculate Sampling Rates
45 minutesDetermine update rate for each sensor and bus bandwidth for combined data throughput.
Build and Wire Sensors
2-4 hoursMount sensors, wire to MCU buses, implement drivers, and add digital filtering.
Test and Debug
1 hourVerify each sensor reading, measure communication latency, and test fused output.
Tools Used

Set per-sensor polling frequency meeting Nyquist requirement.
- Ultrasonic Sensor RangePrimary
Configure proximity detection thresholds and timing.
- Encoder ResolutionSupporting
Calculate ticks per revolution for odometry resolution.
- Communication LatencyReference
Measure bus latency to verify control loop timing budget.

Sensor TypesTable
Key benchmarks for sensor integration guide.
| Sensor | Rate | Use |
|---|---|---|
| Encoder | 1 kHz | Odometry |
| IMU | 100 Hz | Orientation |
| Lidar | 10 Hz | Mapping |
Nyquist RuleFormula
Sample at 2× highest frequency of signal interest
Kalman FilterStandard
Fuse noisy sensors — predict with model, correct with measurement.
EMI Separation
Motor power wires induce noise on analog sensor lines — route sensor cables separately.
Filter Before Control
Never feed raw encoder or IMU data directly to PID — always filter first.
I2C Scanner
Run I2C address scan sketch before writing drivers — confirms wiring before debugging code.
Safety Notes
- Define safe fallback behavior when a sensor fails mid-run — stop motors rather than continue on bad data.
- Disconnect battery before rewiring sensor buses to prevent short circuits.
