After an intensive week of testing on the competition table at Middlesex University (our only time with the table) our team, “R.Me.R.T”, placed 5th overall which, although not taking us to the world finals in France, was an excellent result considering the timescale of the build. The robot passed the approval phase in time to take part in all four qualification matches. Continue reading
So, a very scary 19 days to go until the competition, and things are starting to get very busy with the project. I don’t want to give too much away on here in terms of tactics and full hardware specs (for obvious reasons) but there are some things that I can report on. Continue reading
Today I took delivery of two 5A bi-directional motor controllers with J1939 CAN-bus interface courtesy of our new Eurobot team sponsors, Axiomatic, of Mississauga, Canada.
I’m very impressed by the customer service from these people, I feel they’ve really gone out of their way to answer my questions and make sure their product is fit for my intended use. The AX100600 controllers look very well made (using weight as a sign of quality!) and the ‘Electronic Assistant’ software looks very comprehensive and useful. POC videos will follow when we’ve sourced the correct connectors and got something moving (The impatient side of me was considering soldering wires directly to the pins for now, but seeing the quality of these units, this would be sacrilegious!). The beauty of CAN is that they can be easily tested and calibrated on the bench, before connecting up the robot’s main controller (more on this soon, too!).
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. Continue reading
