AQA 7517 4.4.1.3: Abstraction

The free BugBot lessons that teach this point, a robot to try it on, and the past-paper questions that test it.

Lessons that teach it

1. A2.4 Abstraction and models Recursion and computational thinking
   Representational abstraction, generalisation, problem reduction, and a grid model of the mat that differs from reality.
2. A2.10 Project: out of the dead end Recursion and computational thinking
   Model a maze, solve it by recursive backtracking, and drive the robot out along the route.

Try it on a robot
