FarPoint MissionFarPoint Mission

• L.A.R.R.-E. must successfully navigate a “canyon” maze

• L.A.R.R.-E. must successfully locate a light source (robogold) on a black stripe located on the “plain” after leaving the canyon. The robot will stop when it “discovers” the robogold and play a sound to indicate that it has found the correct place.

• Programmers will be allowed to change programs only once during their Mission trial. They will not be allowed to make any physical changes to their design of L.A.R.R.-E. once they start the trial. Limited repairs will be allowed.

Basic Equipment and Materials ListBasic Equipment and Materials List

• 5-6 Lego Mindstorms robotic kits• Minimum of 6 Batteries for each kit• 5-6 Windows based computers (98 or above)• Introductory Powerpoint presentation• Materials to construct the “canyon” and “mining”

challenges• RIS (Robotic Invention System) software for

each robot• Handouts as needed throughout the “mission”

Bloom’s TaxonomyBloom’s Taxonomy

• Analysis—students will use analytical skills to determine the steps needed to to solve the problem.

• Synthesis—students will use and modify basic skills learned in tutorial “missions” to solve new problems

• Evaluation—students will evaluate their current solutions in light of the presented criteria for success and make changes accordingly

Algorithm Algorithm

• 1. Move forward whenever possible

• 2. Backup and turn whenever a wall is hit

• 3. Locate the place with the light

• 4. Go to the place with the light

• 5. Stop

• 6. Play a tone or tune
