Robot Friends: First Builds
First robot, first reactions to the real world.
What students learn
A friendly first encounter with robotics. Students put together their first programmable robot, learn how sensors and motors talk to each other, and write the logic that makes their robot react to the world.
What a robot actually is — a machine that senses, decides, and acts. Students get hands-on with motors, sensors, and the simple programs that tie them together. By the end they can explain (and demo) what their robot does and why.
Module-by-module
-
01
What is a robot?
Input → process → output. Take one apart and explain it.
-
02
Drive and turn
Wheels and motors. Robot drives a square.
-
03
Sense the world
Distance, line, light sensors. Robot stops at a wall.
-
04
Make a decision
If/else logic in blocks. Robot follows a black line.
-
05
Make it react
Sense + decide + act. Robot avoids obstacles.
-
06
Showcase build
Pick a behavior and demo it (sumo, dance, maze-solver).
What they make
A sumo-style robot that drives, senses obstacles, and reacts.
Walk away with
Programmable logic intuition. Sensors vs. actuators as a mental model. Confidence taking apart and rebuilding a real machine.
