Robotic Systems

Designing the sensor–control–actuator–power–mechanics chain as a feedback system.

Completion evidence: Block diagram, state machine, threshold/feedback tests and safe-stop behaviour.

Map states, sensor thresholds, motor commands and safe stopping for a line-following or obstacle-avoidance system.

The order is recommended. Before a project page, complete evidence from foundation, practice and debugging lessons.

Designing the sensor–control–actuator–power–mechanics chain as a feedback system. A correct example alone is therefore insufficient. Completion evidence should be block diagram, state machine, threshold/feedback tests and safe-stop behaviour, tested with normal, boundary and invalid inputs.

In the first cycle, pair foundation and application among The Sense–Decide–Act Loop, Fault Analysis, Line Following, Obstacle Detection, Choosing a Power Source. Predict the result, run or measure it, then explain any difference. Even when prediction and reality match, state which changed condition would break the result.

In the second cycle, complete this laboratory: Map states, sensor thresholds, motor commands and safe stopping for a line-following or obstacle-avoidance system. Do not close with one successful screenshot. Keep the input table, expected behaviour, actual behaviour, error or measurement and the correction in one file.

In the final cycle, connect The Basic Parts of a Robot, Chassis and Mechanical Design, Wheels, Gears and Torque, Building a Test Course, Remote Control. Let one lesson's output become another lesson's input; show where safe stopping is needed when data type, unit, wiring, timing or user expectation changes.

Repeat the same task one month later with less source support. Compare not only speed or appearance but test coverage, explainability, safety and whether another person can rebuild the work.

Use the foundation produced in The Sense–Decide–Act Loop as an input to Project: Obstacle-Avoiding Robot. Then show in Remote Control how the same idea changes under the limits of a larger system. This bridge carries the goal of designing the sensor–control–actuator–power–mechanics chain as a feedback system. beyond one isolated example.

Add three columns to the block diagram, state machine, threshold/feedback tests and safe-stop behaviour file: knowledge carried from the previous lesson, condition changed in the new lesson and result observed in testing. Sharing a word does not establish a connection; one lesson’s output should genuinely become the next process’s input.

Test the connection through this laboratory: Map states, sensor thresholds, motor commands and safe stopping for a line-following or obstacle-avoidance system. After the first attempt, add an edge condition such as empty data, wrong type, disconnected input, extreme value or user error. Record whether the system remains understandable and safe beyond the normal example.

• Name the previous lesson output
• State the one changed condition
• Separate expected and actual result
• Define safe stopping or error feedback
• Make one change in the second version
