Who it is for
Age is a starting point, never a limit. A learner who can show what this unit starts from can begin here at any age.
- How they learn
- By designing systems in C++ or Python, using simulation as preparation, and proving behaviour with measured trials.
- The adult's role
- An adult reviews safety, tools and higher-risk subsystems.
- Session
- 90–120 minutes
- Hardware
- Arduino, Raspberry Pi Pico, ESP32 or a Raspberry Pi computer. Many of these boards are 3.3 V: use level shifting for 5 V parts. Advance only after driver and power competency.
Starts from
Servo angles
Move a servo to a chosen angle and back.
Built in R10-U3 Create an Automatic Response
Calibration
Calibrate a sensor for the real conditions.
Built in R10-U2 Measure Distance
CAD mechanisms
Design a mechanism in CAD, with its degrees of freedom and loads.
Built in R15-U1 Mechanisms and CAD
Power budget
Estimate current draw and battery life, and avoid brownouts that reset the board.
Built in R13-U1 Mobile Robot Hardware
Builds, and what it is the input for
Joint control
Move robot joints to measured, repeatable positions.
Input for R15-U3 Coordinates and Reach, R16-U2 Object Detection and Actuation
