Fig. 4From: Fostering computational thinking through educational robotics: a model for creative computational problem solvingPlayground of the robot lawnmower mission with Thymio. The playground consists of a wooden fence surrounding an area (45 × 45cm) representing the lawn. One of the nine squares represents the garage, the starting position of the mission (left). The task is to program the Thymio robot so that it passes over all eight lawn squares while avoiding any collisions with the fence (right)Back to article page
