The Macalester Student Chapter of the ACM

(Association for Computing Machinery)

invites you to the 2nd annual

Lego Robot Competition



When: Saturday, April 20, noon to 5pm

Where: Gallery of the Olin-Rice Science Center

Macalester College

Contact: Susan Fox (fox@macalester.edu)



The Competition

Teams of students will work for roughly one month to build and program a Lego-type robot to perform a specified task. Each team should have three students, and should build a single robot with a single controller. Each team will demonstrate its robot during the robot competition time, having a chance to explain their design. Prizes will be awarded based on speed and accuracy, with bonuses for clever designs. The robot's task will be posted on the Robotics Lab web site.


Demonstrations

Any student who has done a cool or fun project relating to robotics or artificial intelligence is invited to give a demo of their project on this day. Demonstrations will occur simultaneously with the competition. The default demonstration time is fifteen minutes, but variations are possible. Let Susan Fox know if you'd like to demonstrate a project. You'll need to provide a project title and two-sentence description by Wednesday, April 17.


Robot Requirements

In order to allow for the broad variation in robot kits available, the competition will have minimal restrictions on what sort of robots may be used. Any Lego-scale robot is acceptable, though those using a non-Lego chassis (for example, a Rug Warrior) or a controller other than Mindstorm, Handyboard, or one of the Handyboard's precursors should seek prior approval from Susan Fox.

Each team must create one robot, controlled with a single controller. The robot should operate untethered from a base computer. The robot must fit within a 10 inch x 10 inch x10 inch box to start with. Otherwise, the form and structure of the robot is not constrained. The robot will almost certainly need at least light sensors and touch sensors. There is no limit placed on how many sensors the robot has, nor on the use of other sorts of sensors. We may award prizes separately based on sensor differences, if performance is clearly affected.


On the Day

Teams may arrive at any time from 11am onward, to set up and get ready for the contest. Lunch will be provided to participants.

Promptly at 1pm, the contest will begin. Each team will be assigned a 20 minute time slot: 5 minutes for set-up and 15 minutes for the robot to complete the task. Since the point of this event is as much fun as competition, the time schedule will be flexible. If a robot fail to perform as expected the team may try again at a later point.

Teams will have access to computing resources (Windows, Mac, or Linux) to make last-minute changes to the robot's software. Each team should bring any required connectors and software. Teams are also welcome to bring their own laptops to use. Table space will be provided for teams to work on their robots.


Signing up

Students at schools other than Macalester should contact their local faculty coordinator about forming a team. At Macalester, contact Susan Fox. By the Wednesday before the event, all schools should inform Susan Fox of the number of teams participating, for planning the lunch event. Please inform her of any special requirements (computing, personal) that pertain to the event itself.
