Following the mixed success from the previous year, Darren Lewis and I returned to Eurobot in 2010. This time the competition was to collect various objects from the table;
Tomatoes – lightweight juggling balls positioned at known points on the table
Corn – plastic rods located in holes on the table, also at known positions, but with unmovable black corn placed in random positions within the pattern.
Oranges – heavyweight juggling balls positioned on ‘trees’ at the top of a ramp at the back of the table.
Once the items were collected, they were to be taken to the corner diagonally opposite the starting zone and deposited in the bin. The team with the greatest weight of items at the end won.
We had very little time for this one, as we were working on our placement at the same time, so there was around 4 weeks build and programming time. We devised a very simple machine that collected all 6 oranges from the trees, located the scoring bin using an infrared beacon, and deposited them.
The simplicity of the machine meant that, on reliability, it out-performed many of the bigger teams in the world final.
The team made 3rd place in the UK finals, and 8th in the World Finals.
