Computer Science --- Haas --- Karel Project MineBot

Objective: Create a Karel J Robot program which uses for and while loops

Complete the program below which has a robot walk along the ground looking for mine shafts, when a mine is found the robot digs to the bottom and picks up all beepers along the way. The robot then climbs back up and moves forward. The robot must be able to find all mines in a 10 by 10 world. Start the robot from the position indicated below. The robot must be able to handle mines in any location and any depth.

• Make a new robot class called MineBot which extents the Robot Class.
• The MineBot class must have methods called digDown, climbUp, moveEast, and exploreMines.
• The digDown method moves a robot, facing any direction, down a mine shaft and picks up all beepers along the way. It must also keep track of the number of beepers that it picked up.
• The climbUp method should move a robot, facing any direction, from the bottom of a hole up to street level.
• moveEast should move a robot, facing any direction, east one block.
• The exploreMines method explores the mine world by repeating methods: digDown, climbUp, and moveEast a given number of times. Then it puts down the total number of beepers that it picked up along the way.
• Make an interger variable called beepCount which keeps track of the number of beepers picked up. At the end have mineBot put down in one pile the same number it picked up.
• MineBot should be called from MineBotTester which creates a new robot object of class MineBot. This program creates a MineBot and runs exploreMines().

Below is a before and after example of a world with mines, however MineBot should be able to find mines in any location.
