  1. Team Unknown Kyri David Andy Sami Cheryl the dog

  2. Teamwork • We discussed all the problems we came up against. • We came to solutions amicably. • We divided the tasks between us, in order to work to each of our individual strengths.

  3. Roles played • Kyri • Programming • Building • David • Programming • Building • Andy • Presentation • Building • Sami • Presentation • Building • Cheryl • Mascot

  4. Why we chose our Sensors • Light Sensors • Easy to use • Reliable • Would pick up the masking tape on the dark carpet • Touch Sensor • To detect the taller cans • Easier to use than a light sensor for detecting obstacles • Motors • Necessary • Needed to move the robot itself

  5. Why we chose our Design • Why we opted for the design: • Stability/Reliability • Seemed most suited to our needs • Tracks vs Wheels • Lower centre of gravity • More suited to the rough surface of the carpet • Slower (slow and steady wins the race) • Programming • Have robot run. • Light sensors pick up change in light. Robot then reverses and turns accordingly. • Touch sensor on front. Picks up taller can, and ram turns to correct direction.

  6. Final Sensors vs Chosen Sensors • We initially asked for: • 3 light sensors • 4 motors • 2 touch sensors (possibly) • We got: • 2 light sensors (we won the coin toss…) • 4 motors • 1 touch sensor • Differed because: • Availability • Changes to our initial ideas

  7. Experimental Methodology • We used a simple track to test out our initial ideas. • Once we had developed our programs somewhat, we designed a much more challenging course to see how our robot fared in a number of different situations. • Initially we made our track to test if the light sensors could detect the masking tape. • Once that had been achieved, we added cans to the track to see if our robot could achieve objectives 2 and 3.

  8. Lessons Learnt • There are always limitations to a good idea. • Resource management. • Teamwork can cause conflict. • (don’t stay up to ridiculous hours of the morning so you’re too tired to write the presentation…)

  9. Problems • We underestimated the weight of the bean cans. • So we had to redesign the structure of the robot to make it stronger. • (which did actually improve it…) • Problems connecting the bumper to the chassis. • So we had to be all inventive and stuffffff and think about how to connect it. • The mechanism we used to knock the cans out of the way obstructed the touch sensor. • So we moved it forward so that it wasn’t obstructed anymore….

  10. Future Development • If we had more time we would: • Use more sensors. • Use the newest RCX block available. • This would allow more sensor inputs. • We’d use IF functions more effectively. • (we’d also go to bed early….*snore*…im sure that as you’re reading this at least one of us is trying not to yawn).
