Mars Rover Code Kata http://kata-log.rocks/mars-rover-kata The Problem A squad of robotic rovers are to be landed by NASA on a plateau on Mars. In this activity you'll use code to design a game inspired by the way NASA rovers navigate on Mars. Every child can code! Please A rovers position and location is represented by a combination of x and y co-ordinates and a letter representing one of the four cardinal compass points. Determine how the mission will be deemed a success (the rover reaches the target) or a failure (the rover collides with a hazard). Implement commands that move the rover forward/backward (f,b). Your game will challenge players to drive a Mars rover from one location to another while avoiding hazards. Sign Up.

This plateau, which is curiously rectangular, must be navigated by the rovers so that their on-board cameras can get a complete view of the surrounding terrain to send back to Earth. The possible Please Implement commands that turn the rover left/right (l,r). Now that we've gone over the class, let's check out the tests. Is it too hard or too easy? In order to control a rover, NASA sends a simple string of letters. Implement commands that move the rover forward/backward (f,b).
