On this project we will land Spaces Probes on the surface of Mars. In order to ensure a sefely landing and surface operation, a Probe needs to be loaded with its touchdown coordinates and an exploration program using a specific instruction set.
A limited instruction set capable of describe the exploration area, probe positioning and bearing, and movement commands is available:
Exploration Area
# x axis | y axis
5 5Probe Position and bearing
# x axis | y axis | direction
1 2 NMoving instructions
# L = left | R = right | M = move
LMLMLMLMMNotice when issuing an orientation command (L and R), the probe will only rotates 90 degrees and no movement is applied. In order to actually move the probe, a M command must be issued.
When the Space Probe lands, it sends a signal informing the arrival coordinates:
# X axis | Y axis | direction
1 3 NIf the Space Probe reaches on the limit of area, a message will be sent:
Houston, we have a problem. We reached our limit.
To run you need the Ruby installed, you can follow the instructions: Installing Ruby
git clone git@github.com:rpontes/exploring-mars.git
cd exploring-mars
ruby bin/exploring_mars.rb
