1 American Society of Mechanical Engineers, Student Chapter of the University of Southern Indiana is proud to present the USI Robotics Competition 2011 with support from the USI Pott College of Science and Engineering, Southwestern Indiana STEM Resource Center, ASME Center for Leadership and Diversity, Indiana Space Grant Consortium, and the Student Government Association of USI This document, along with supplemental resources, is available online: USI Robotics Competition 2011 Friday, April 15, 2011 USI Business and Engineering Center 4:00 pm 8:30 pm Background The USI Robotics Competition was first announced in Fall 2007 as a collaborative event between USI's student chapters of the American Society of Mechanical Engineers (ASME) and the Institute of Electrical and Electronics Engineers (IEEE). The competition was held April 18, 2008 and was acclaimed as a great success by all involved. It reached 56 students in the Evansville area in 2008 and over 100 students competed in The competition is organized and run by USI ASME with the support of the faculty, staff, and students in the USI Department of Engineering. Now an annual event, the USI Robotics Competition is in its fourth year. This year our goal is to expand the Robotics Competition into the Kentucky and Illinois regions. Robotics is a rapidly developing field in research and industry. With the USI Robotics Competition, students have the opportunity to learn about foundational elements of this field by designing, testing, and implementing LEGO robotic systems. By expanding our Robotics Competition, we hope to reach a larger demographic and promote the STEM initiative in the Tri-State area. Registration Registration for the Robotics Competition is due April 1 by 5:00 pm CST. Teams can register online at Cost This event is free and open to the community, thanks to the generous support we have received.

2 Background We ve received an emergency transmission from our Martian mining site. A satellite has been sent to investigate and we have determined that a small meteor has caused damage to the communications building. Your mission is to develop a robot that will assist in readying the base for a recovery team. Objectives Primary: Starting at the landing zone, Navigate via the road to the east gate. Harvest ore and deposit it at the refinery. Secondary: Clear the debris in front of the communications building. Deactivate the emergency beacon, signaling the all clear for our recovery team. Gameplay The robot should start in the landing zone, as shown in the Course Specifications section. There are two acceptable paths for navigating to the gate: 1. Following the road, navigate south around the communications building. 2. Following the road, navigate between the communications building and the hanger. Beware debris! If possible, clear the debris from the road and deposit it the waste processing facility. After reaching the east gate, it may proceed to the ore field and begin gathering ore (marbles). Ore is to be deposited at the refinery, north of the ore field, by pushing it through the ore refinery entrance. At any time after reaching the gate, the robot may deactivate the emergency beacon by pressing the button on the south face of the plateau. Rules Each round shall last 2:30 minutes. When time expires, all points that have been accumulated during the round shall be totaled. The entire robot shall begin inside the landing zone. (See Course Specifications) While robots may temporarily extend beyond the boundaries, they shall begin each round within the boundaries of the course. When competing, team members shall stand in designated areas only. Persons shall not touch the course or robot during a round; doing so can result in disqualification. Teams shall not to touch the robot after a round begins. After 2:30 minutes, the judges shall stop the robots. Teams shall wait to remove the robot until a score has been calculated. If at any time, a team would like to terminate their round (stop the clock) they shall announce the intent to the judges. Time shall be recorded and the judges shall stop the robot. The robot shall not be removed from the course until a score has been calculated. Should a robot contact a surface outside the course, the round should end immediately, and points shall be totaled. Robots shall not cause damage to the course. Purposeful damage of the course shall result in immediate disqualification. No projectiles shall be permitted. Use of projectiles can result immediate disqualifications. In certain situations, judges may allow a rerun (e.g., if a robot fails to move) Judges shall have final discretion over all matters.

3 ROBOTS MAY BE INSPECTED AT ANY TIME BY THE JUDGES FOR COMPLIANCE WITH THE FOLLOWING SPECIFICATIONS: The size constraint for the assembled robot shall be 12 x12. There is no height restriction. Robots may expand beyond this size after a round begins; however the robot must start within the 12 x12 landing zone. (Please note, that the smallest opening on the course is 8.) Robots shall be assembled using only the pieces provided in approved LEGO Mindstorms sets. This does not include, however, the box, tub, papers, storage compartments, etc. The robot shall be built using one of the following LEGO Mindstorms sets: RCX o Team Challenge Set (9794) o Robotics Invention System 1.0 (9719) o Robotics Invention System 2.0 (3804) NXT o Education set (9797) o NXT 1.0 (8527) o NXT 2.0 (8547) If you have a kit other those listed above, please feel free to contact us and we will determine if it is an acceptable kit. Kits other than those listed above are prohibited, and the use of other systems can lead to disqualification. Only the LEGO elements of one kit shall to be used per team. No pieces shall be modified in any way. All robots shall be fully autonomous. No remote control or outside interference is allowed. Outside interference includes, but is not limited to loud noises (e.g., clapping) or lights. Leads (or wires) shall not be used to hold a robot together. Robots shall be assembled prior to the competition; however there will be time between rounds for revisions. Teams are allowed only one robot to compete. If modifications are required, this may be done between rounds. Teams may personalize their robot with a small pennant (up to 2 x 3 ) so long as it performs no mechanical function. Page 3 of 9

4 Team Constraints Any local middle school, high school, or college student may compete. Teams of up to four students are to work together to design, build, and program a LEGO Mindstorms robot to complete the mission. To allow a greater diversity in the competition, both RCX and NXT kits are permitted. Teams will be placed in divisions based on their grade level. Divisions shall be as follows: Middle School RCX Middle School NXT High School College/University RCX kits are no longer available directly through the LEGO Group. If you plan to purchase new kits, we recommend the NXT set. Programming There are two computer labs available for teams to use during the competition. Teams may also bring a portable computer for use within the breakout regions. Any programming language is acceptable (RoboLAB, NXT-G, NQC, NXC, RobotC, LeJos, Java, MATLAB, VBA), though the program shall be the original work of the students on the team. Teams should bring any software/equipment needed to program their robots. IR towers, Bluetooth dongles, and USB cables will NOT be provided during the competition. Students shall not program their robots within the Atrium, as this may cause interference for nearby robots. USI computers shall be used for programming only; personal web browsing (including and social networking) will not be permitted in computer labs. Anyone abusing this privilege shall be asked to leave the labs. Computers cannot be reserved when not in use. Scoring Scores shall be calculated based upon the figures in the following table: Objective Detail Points Max Pts. Road Navigation Reach the east gate 30 pts. 30 pts. Depositing Debris Each piece of debris deposited 1 pts. 10 pts. Ore Processing Each unit processed 1 pt. 40 pts. Bonus for each fifth unit processed 5 pts. Beacon Press the button on the Plateau. 20 pts. 20 pts. Total 100 pts. Teams will be allowed to attempt the course during two separate rounds. The higher of the two scores shall be the final score. In case of a tie, the robot with the fastest time shall be the tie-breaker. Page 4 of 9

9 Frequently Asked Questions (FAQ) Q: Is the LEGO NXT accessory kit (9648) permitted? Which kits can we use? A: No. Kits are limited to those described in Robot Specifications. If you kit is not listed, contact us and let us know. We'll make an informed decision based on the contents of your kit. Competing with a kit that is not approved may result in disqualification. Q: Must the robot start on the yellow line? A: The robot may start in any orientation or location within the landing zone. The landing zone is 12 x12 area in the northwest corner of the base. The robot must begin entirely within this zone. Q: What type marbles will be used? A: The marbles will be standard marbles. The marbles are translucent blue. Q: The button: what color, size, shape, and how to press? A: The button is a momentary bumper switch similar to the one shown below. The lever arm is 5-6 inches and curved to allow a press with minimal force from many directions. See the course photos online for a detailed photo of the assembly. Q: What happened to the metallic strip? A: The metallic tape at the end of the road has been replaced with a 1 flat black line. This change was made because the intensities of reflected light on the grey road and the metallic tape were too similar. Black offers a better contrast with the grey road. Q: Will we be able to practice on the course? A: Yes. Two courses are kept in USI s Business and Engineering Center. Send an to usiasme@gmail.com to arrange a time to visit and use the course. There will not be a practice course at the competition, however, as both courses will be used for competing. Send your questions regarding the USI RC11 to usiasme@gmail.com. Page 9 of 9
