Botball
Botball is an educational robotics program that focuses on engaging middle and high school aged students in team-oriented robotics competitions. Thousands of children and young adults participate in the Botball program. It has been active since 1998 and features a robotics curriculum which focuses on designing, building and programming a pair of autonomous robots. Teams use a standardized kit of materials, document the process and then compete in a tournament in which the challenges change annually. All materials in the kits are exactly the same for every team around the world, so there are no unfair advantages. Botball teams are mostly based in the United States with over 300 teams and local tournaments in more than a dozen regions. In recent years it also holds an annual Global Conference on Educational Robotics, with an international tournament that attracts teams all over the country as well as from Mexico, Austria, China, Uganda, Poland, Qatar, Kuwait, and Egypt.
Overview
Botball's mantra is that “Today’s Botball kids are tomorrow’s scientists and engineers.” The program is managed by the non-profit KISS Institute for Practical Robotics whose vision is to use robotics "to stimulate and engage students in exploring their potential in engineering, science and math." The goal of Botball and KISS to educate the workforce of the future and to engage students in science, technology, engineering and math. This objective is shared by the NASA Robotics Alliance Project which partners with Botball and other robotics education programs. NASA RAP's mission is “to enable the implementation of future robotic space exploration missions.” NASA sponsors Botball through providing technical mentors and other resources. It also hosts an online free course in Programming robots in C, featuring a controller that was used in Botball NASA RAP sees Botball as an opportunity to reach out to its future workforce and provide relevant hands-on experience and necessary skills to potential future NASA scientists.Botball is known for the sophistication and complexity of its robotic competitions. What differentiates Botball from other student robotics programs is that the robots are autonomous; therefore, they are not directed by remote control. Students use computer science to program the robots to recognize challenges and then attempt the objectives of the competition. The robots contain several types of sensors and also two digital cameras for their computer vision systems. Robot Magazine, highlighted in an article the gameplay and systems, "Every year the game offers different challenges at varying levels of difficulty, so participants can focus on harder goals, or find simpler solutions, based on their abilities ... Botball uses the CBC2, a powerful robot controller that easily interfaces with a large number of sensors and effectors and features an ARM 9-based CPU/Vision processor running LINUX, an ARM 7-based DAQ/Motor control system, and integrated display and touch screens that are easy to use. The CBC2 uses the KISS-C Integrated Development Environment and its libraries, especially designed to be friendly to users with vastly different programming experience. Both the CBC2 and KISS-C were developed by KISS Institute and are used in university research programs, as well as the Botball Program."
Botball competitions revolve around using autonomous robots to complete a series of tasks within a set time limit of two minutes. Sensors and digital cameras give input to the robots, which help to identify objects. Beforehand and between rounds of competition, participants program the robots using an integrated development environment. Botball competitors also must complete online documentation of their progress and their goals to score points.
A similar competition for adults, called the KIPR Open, commenced in 2001.
History
The KISS Institute for Practical Robotics is a 501 not-for profit education and research organization, incorporated in Virginia in 1994. It is headquartered now located in Norman, Oklahoma. KISS Institute was co-founded by Ms. Cathryne Stein, Dr. David Miller, and Dr. Marc Slack with the objective of creating a center for a system of technology and science education programs based on robotics, and to use robotic technology to better serve the public good. Ms. Stein has recently retired as Executive Director; she is succeeded by Dr. Steve Goodgame, an experienced educator. Dr. Miller is the Chief Technology Officer, as well as the Wilkonson Professor of Aerospace and Mechanical Engineering at the University of Oklahoma. Dr. Miller is a former JPL employee, having made significant contributions to NASA’s Mars Rover project.Botball was first started in 1997 by the KISS Institute for Practical Robotics.
Technical components
At the start of each Botball season, each team receives a kit of components with enough material to build two completely autonomous robots.The mechanical components used in Botball are Lego Technic bricks. The electrical components have included a variety of robot controllers, of which each team's kit contains two, as well as a number of different sensors and motors.

Programming language

Rules
Robot construction
Robots can only be constructed of the parts included in the kit.- A maximum of 93 square inches of paper may be used. The paper used must be black or white.
- String may be used in the construction of the robot; up to 36 inches may be used.
- Ten #19 rubber bands can be used.
- The metal parts included in the kit cannot be broken into smaller pieces.
- Of the metal parts, only the flat bars and plates may be bent.
- The only removable parts on the iRobot Create are the rear wheel, the drive wheel clips, and the rear cargo bay wall. Any other parts cannot be removed or disassembled.
- The area the robots start in varies by year. In 2010 the starting area is 22 by 31.5 by 15 inches
- *The robot must be under a certain height constraint at the start of the match.
- A team may have four different objects on the field.
- *All the objects must fit into the starting box.
- No wireless communications are allowed during the tournament.
Game play
The field size depends upon the game; this one totals 8 ft by 12 ft, with most of the surface surrounded by 1-1/2 inch PVC pipe. When two teams compete against each other, they start on opposite ends of the playing surface and have 120 seconds to move around objects and score points. At the end of a game, the robots must stop themselves, at which time a judge scores the game to determine which team's robots won.
Scoring
For the 2008 season, the initial score of a team is 0 and then points are calculated at the end of the game using the point values found in the following table:Side 1 | Solarium | Shelter | Space | Side 2 | |
Satellite | -4 | -6 | -6 | 0 | N/A |
Solar sail | -3 | -3 | -3 | 0 | N/A |
Plant | 1 | 6 | 0 | 0 | N/A |
Crew | 1 | 0 | 6 | 0 | N/A |
Garden | 5 | 15 | 3 | 0 | N/A |
Botguy | 5 | 3 | 15 | 0 | N/A |
Team 1's robot | 0 | 0 | 0 | 0 | 15 on their side and 30 in shelter |
The Botball season/Competition
The Botball regional season runs from late January to about early May. During this time,students attend a two-day workshop and are trained in learning the basics of computer programming. Students have six to eight weeks to program, build, and test their robots. As the robots progress, students have to document how their robot is coming along as well as the tweaks and changes they made from the original design. During the regional competition, there are three rounds: Seeding, Double Eliminations, and Alliance.
Seeding: Seeding is where one team goes against themselves but students still earn points and there is an award for the team that scores the highest on the seeding round. Double Eliminations is where the actual competition begins and where teams compete against each other until they are eliminated twice.
Alliance Matches are matches for teams who have been eliminated twice early in the competition. Two teams are paired up together and they compete for points
