Illustrative wheeled robotics prototype with a yellow gripper on a workbench
Illustrative prototype created for this edition. Not a historical team photograph or a reviewed product.
Two equal-length levers with different pivot positions
Original concept illustration: two pivot positions, one arm and one load. No test result is claimed.

Project one: linkage comparison

Draw a simple arm in two positions. Label the pivot, the input motion and the load. Compare the distance moved at the end of the arm when the pivot changes. Keep dimensions consistent so the drawing explains the comparison.

Feedback loop: compare, act, measure and repeat
A control-system concept: measure the result before choosing the next action.

Project two: wiring that can be inspected

Create a diagram showing power, signal and connection labels for a small demonstration circuit. Document the intended supply and component ratings before assembly. Use the diagram to check the build instead of relying on memory.

A test notebook with fields for question, setup, result and next change
Documentation prompt: record the setup, not only the finished object.

Project three: a repeatable test

Photograph or sketch the starting setup, mark the measurement points and include a results sheet. Obtain permission before publishing anyone’s image. The project prompts here are new; former students’ photographs have not been reproduced.
