From component knowledge to system design
| Application | Sense | Compute and act | Measure success |
|---|---|---|---|
| Indoor delivery rover | Encoders + distance sensors; localization as needed | Planner → wheel speed loops → geared motors | Stopping distance, path error, runtime, and recovery. |
| Inspection station | Camera + presence trigger | Image processing → pass/reject decision → actuator | False accepts/rejects under varied lighting. |
| Small pick-and-place arm | Joint feedback + object detection | Pose estimate → limited trajectory → joint drives | Repeatability, cycle time, payload, and safe stops. |
| Greenhouse dosing | Calibrated environmental / flow sensors | State machine → pump driver with timeout | Delivered volume, leak detection, dry-run protection. |
| Assistive demonstration | User input + joint/force sensing | Constrained controller → low-force actuator | Predictable response and independent stop behavior. |
Write a measurable requirement
Replace “avoid obstacles” with “stop before the marked boundary at the chosen test speed, including sensor delay and braking distance.” For an illustrative speed of 0.30 m/s, 0.10 s reaction time, and 0.50 m/s² braking deceleration, the ideal stopping distance is v·t + v²/(2a) = 0.12 m. Real testing needs additional margin for uncertainty and surface conditions.
A build sequence that exposes problems early
Integrated prototype
Connect the pipeline and test with low speeds and restrained loads. Change one parameter at a time so causes remain visible.
Repeatable experiment
Write down the surface, load, battery condition, software version, and measurement method. Repeat trials and report spread, not just the best result.
Choose your next project
Start with the obstacle-avoiding rover, extend it with validated distance measurements, and then add wheel feedback. For a stationary mechanism, begin with the joint motion lesson.
