Parki is composed of two motorized wheels (1) in the back and two ball casters (2) in the front. The main platform (3), where all wheels and balls resides has a rotating plate (4) made of aluminium. In the left there is a small arm (5) that turns 180° which has pliers (6) in its end. Above all these, we have a small single-axed arm (7) that goes up and down. Finally we added two upper plastic levels (8) to place the electronic circuits. The pliers enables parki to take the disks one by one and put them in colons above the moving plate while the small arm (7) places the brick above the construction columns.

This post is intended to describe the French Robot Cup 2009.
Parki is a robot created to participate in the 2009 Eurobot contest and the 2009 French Robot Cup. The rules for this contest might be found here or here (direct link) or here in french. This event is organized by “Planète-Sciences”. You can have more info about this Robotics Cup here and about eurobot here. And finally one more link about our team Kelebulc.
The objective of this years contest is to build the highest temple in 90 seconds. The elements to build it can be found in the floor, spared as in 10 different configurations and in the distribution centres located in the opposite wall of the starting square. Our robot, already had a brick to complete its temple.
The field as shown below was completed with 4 disks (construction elements). The construction zones are coloured in brown and the temples built on them depend on the height of the construction zone. The circular centre zone is the highest one. The one located in the bottom centre is mid-high and in its sides, they’re floor levelled.
The field of the 2009 Eurobot Contest.
The robot is supposed to build either green or red temples. Your starting position tells you the colour. The construction elements distribution is not known until the match has started so we had to think about having a strategy that would work in all (10) cases.
We designed our robot to be simple, light-weight and easy to build. We tried the best to make it reliable and oh boy! we did it! We achieved all of our goals.
