A simulation of a toy robot moving on a square tabletop of dimensions 5 units x 5 units.
- There are no obstructions on the table surface.
- The robot is free to roam around the surface of the table.
- The robot is prevented from falling to destruction. (Any movement that would result in the robot falling from the table is prevented, however further valid movement commands are still allowed.)
- The first command the robot will respond to is a valid PLACE command.
Add this line to your application's Gemfile:
