VEX RoboticsVEX Robotics is a robotics program for elementary through university students and a subset of Innovation First International. The VEX Robotics competitions and programs are managed by the Robotics Education & Competition Foundation (RECF).[1] In April 2018, VEX Robotics Competition was named the largest robotics competition in the world by Guinness World Records.[2] There are four leagues of VEX Robotics competitions designed for different age groups and skill levels:
In each of the four leagues, students are given a new challenge annually and must design, build, program, and drive a robot to complete the challenge as best as they can. The robotics teams that consistently display exceptional mastery in all of these areas will eventually progress to the VEX Robotics World Championship. The description and rules for the season's competition are released during the world championship of the previous season. Starting in 2021, the VEX Robotics World Championship has been held in Dallas, Texas each year in mid-April or mid-May, depending on which league the teams are competing in.[8] VEX V5VEX V5 is a STEM learning system designed by VEX Robotics and the REC Foundation to help middle and high school students develop problem-solving and computational thinking skills.[9] It was introduced at the VEX Robotics World Championship in April 2019 as a replacement for a previous system called VEX EDR (VEX Cortex). The program utilizes the VEX V5 Construction and Control System as a standardized hardware, firmware, and software compatibility platform.[9] Robotics teams and clubs can use the VEX V5 system to build robots to compete in the annual VEX V5 Robotics Competition.[10] Construction and Control SystemThe VEX V5 Construction and Control System is a metal-based robotics platform with machinable, bolt-together pieces that can be used to construct custom robotic mechanisms.[9] The robot is controlled by a programmable processor known as the VEX V5 Brain.[11] The Brain is equipped with a color LCD touchscreen, 21 hardware ports, an SD card port, a battery port, 8 legacy sensor ports, and a micro-USB programming port. Usage with a VEX V5 Radio enables wireless driving and wireless programming of the brain via the VEX V5 Controller. The controller allows wireless user input to the robot brain, and two controllers can be daisy-chained if necessary. Each controller has two hardware ports, a micro-USB port, two 2-axis joysticks, a monochrome LCD display, and twelve buttons. The controller's LCD can be written wirelessly from the robot, providing users with configurable feedback from the robot brain. The VEX V5 Motors connect to the brain via the hardware ports and are equipped with an internal optical shaft encoder to provide feedback on the rotational status of the motor. The motor's speed is programmable but may also be altered by exchanging the internal gear cartridge with one of three cartridges of different gear ratios. The three cartridges are 100 rpm, 200 rpm, and 600 rpm. VEXcode V5VEXcode V5 is a Scratch-based coding environment designed by VEX Robotics for programming VEX Robotics hardware, such as the VEX V5 Brain. The block-style interface makes programming simple for elementary through high-school students. VEXcode is consistent across VEX 123, GO, IQ, and V5 and can be used to program the devices from each. VEXcode allows the block programs to be viewed as equivalent C++ or programs to help more advanced students transition from blocks to text. This also allows easy interconversion between text-based and block-based programming.[12] VEXcode also lets students code in C++, which gives the opportunity to learn basic C++, but to collect data from sensors of to move the drivetrain, VEX uses a header file. PROSPROS is a C/C++ programming environment for VEX V5 hardware maintained by students of Purdue University through Purdue ACM SIGBots. It provides a more bare-bones environment for more knowledgeable students that allows for an industry-applicable experience. It has a more robust API that allows for more precise control of the hardware for competition-level uses in VRC/VEX U. It is based on FreeRTOS.[13] VEX V5 Robotics Competition
 Wikimedia Commons has media related to VEX Robotics Competition. VEX V5 Robotics Competition (V5RC) is a robotics competition for registered middle and high school teams that utilize the VEX V5 Construction and Control System.[15] In this competition, teams design, build, and program robots to compete at tournaments. At tournaments, teams participate in qualifying matches where two randomly chosen alliances of two teams each compete for the highest team ranking. Before the Elimination Rounds, the top-ranking teams choose their permanent alliance partners, starting with the highest-ranked team, and continuing until the alliance capacity for the tournament is reached. The new alliances then compete in an elimination bracket, and the tournament champions, alongside other award winners, qualify for their regional culminating event. .[16] The current challenge is VEX V5 Robotics Competition: High Stakes.[16] General rulesMiddle and high school students have the same game and rules. The most general and basic rules for the VEX V5 Robotics Competition are as follows, but each year may have exceptions and/or additional constraints.[17]
Current Game: High Stakes The objective of the game is to score as many alliance rings as possible on stakes. Each field consists of five neutral mobile goal stakes, two alliance wall stakes, two neutral wall stakes, and one high stake. Neutral mobile goal stakes and neutral wall stakes can fit six rings of any color, while each alliance wall stake can fit two rings of the same alliance. The high stake can fit one ring of any color. Each ring scored is worth one point, and the top ring is worth three points. The field also contains two positive corners and two negative corners. Any neutral mobile goal stake can be pushed into the corner. Positive corners double the worth of the rings, while negative corners subtract the worth from their team. The autonomous period winner, the alliance that scores the most points in the 15-second period, gains an additional six points which the negative corners cannot subtract.[18] Previous gamesPrevious VEX Robotics Competition games have included, from 2023-2024 season backwards, Over Under,[19] Spin Up,[20] Tipping Point,[21] Change Up,[22] Tower Takeover,[23] Turning Point,[24] In The Zone,[25] Starstruck,[26] Nothing But Net,[27] Skyrise,[28] Toss Up,[29] Sack Attack,[30] Gateway,[31] Round Up,[32] Clean Sweep,[33] Elevation,[34] and Bridge Battle.[35] VEX IQ Robotics Competition
The VEX IQ Robotics Competition, presented by the Robotics Education & Competition Foundation, provides elementary and middle school students with exciting, open-ended robotics and research project challenges that enhance their science, technology, engineering, and mathematics (STEM) skills through hands-on, student-centered learning. VEX IQ is tailored for grades 5-8. A VEX IQ Robotics set is used with plastic pieces that snap together using pegs, making it easy to construct a robot. Students use a coding software called VEXcode IQ to program the robot. It can be programmed with block-based coding or Python. There are two parts to the contests: Robot Skills, which is a single robot trying to score as many points as possible, and the Teamwork Challenge, where two robots attempt to work together to complete the same task.[36] Current Game: Rapid Relay2024-25VEX IQ Robotics Competition Rapid Relay is played on a 6 feet x 8 feet rectangular field configured as seen above. Two robots compete in the Teamwork Challenge as an alliance in 60-second-long teamwork matches, working collaboratively to score points. Teams also compete in Skills Challenges, where one team tries to score as many points as possible. These matches consist of Driving Skills, where the robots is operated entirely by humans, and Programming Skills, where the robot acts autonomously. The object of the game is to score yellow plush balls into a goal on one side of the field, whilst passing it between each of the teamwork partners robots. The goal wall consists of 4 different holes that can be scored into. Each hole contains a 'switch' that is activated when a ball passes through a hole. Each switch can be activated once per match. Once a ball has been scored, it can be picked up by a designated member of the drive team who places it into a loader on the opposite side of the field. the loader randomly chooses a direction for the balls to be sent. 2 balls can be in play at once during the game. In the last 15s of a match, the designated drive team member can load the balls from a specific zone on the board instead of using the loader.

VEX IQ Challenge Rings-N-Things was the Pilot Program for the VEX IQ Challenge robotics competition program, which launched in April 2012.[52] The game is played on a four-foot by eight-foot field, surrounded by a 3.5-inch tall perimeter. There are four goals and eight rings into which teams can score 36 balls. The field is divided by the ramp.[52] VEX UThe VEX U level competition is a robotics competition for college and university students that uses the VEX Robotics hardware and V5 electronics. The rules are nearly identical for this competition as for the VEX Robotics Competition, but VEX U teams are allowed to take advantage of more customization and greater flexibility than other levels (teams are granted the ability to use 3D printers and use raw materials such as sheet metal and wood). This allows VEX U teams to have more customization on their robots and construct mechanisms that cannot be created solely via the VEX Robotics hardware. Also, their robot creation is limited by the need to find effective costs and a restricted development environment in order to model a real-world situation. Additionally, rather than being limited to a robot size of an 18-inch cube, VEX U contestants had the freedom to use up to a 24-inch cube of space for their larger robot and up to a 15-inch cube for their smaller robot (thus, each team builds 2 robots, and competes against another team's two robots).[53] The VEX U competition, although very similar to the VEX Robotics Competition, has some distinct rules. The autonomous period of VEX U competitions is also longer, lasting forty-five seconds versus the fifteen for the VEX Robotics Competition. As a result, the driver control period is shortened to a period of seventy-five seconds immediately after the autonomous period has been scored, and the autonomous bonus has been awarded to the correct alliance to keep matches at a length of two minutes. VEX AIOn April 25, 2020, VEX Robotics and the REC Foundation announced a new platform of competitions, the VEX AI Competition. The new platforms will use the VEX V5 Construction and Control System, and registration will be available to high school and college teams.[54][55] The competition is fully autonomous and will use an array of new sensors, including the VEX Game Positioning System (VEX GPS); VEX AI microprocessor; VEX AI Vision Sensor with depth perception; VEX LINK, a wireless robot-to-robot communications interface; and the VEX Sensor Fusion Map, a new multi-sensor integration technology which uses sensory data from the robots to render the course in real-time 3D. Each team will build and program two robots. Teams will be able to 3D print and machine parts, use custom electronics, and utilize an unlimited quantity of motors.[56] The pilot program is scheduled to open for registration to university students in the fall of 2020. After registration begins, any high school teams that wish to participate must apply for program admission. Unlike university participants, only those high school teams that show exceptional preparedness for this level of advanced competition will be allowed to compete.[5] VEX AI robotics teams will be able to compete in the VEX AI Competition. Unlike VEX U, this competition will be completely separate from the VRC Competition.[55] VEX Robotics World ChampionshipThe VEX Robotics World Championship brings together qualifying teams from the two VEX Robotics programs: the VEX IQ Challenge, VEX Robotics Competition, with the VEX AI Competition bringing the number to three in 2022. The championship is an international celebration of the robotics community and a final tournament to crown the VEX World Champions in each league. The 2021–24 championships are scheduled to be held in Dallas, Texas.[8] A one-hour special version of the 2016 VEX Robotics World Championship aired on ESPN2 in June 2016.[57] CBS aired a one-hour special version of the 2017 VEX Robotics World Championship on June 11.[58] During the VEX Robotics World Championship, a "Parade of Nations" is held and includes hundreds of students, often dressed in costumes, from more than thirty countries.[59] The 2020 VEX Robotics World Championship was canceled due to the COVID-19 pandemic.[60] On March 30, 2020, VEX Robotics and the REC Foundation announced they would host the first-ever VEX Robotics Virtual World Celebration on April 25, 2020. The event celebrated the accomplishments of all teams and revealed the 2020–21 VEX Robotics Competition and VEX IQ Challenge.[61] During this event, VEX Robotics and the REC Foundation also hosted a Fantasy Robotics simulation for all levels in the VEX Robotics Program, using statistics from state and qualifying tournaments.[62] On January 20, 2021, the REC Foundation along with VEX Robotics announced that due to the COVID-19 pandemic the 2021 VEX World Championships would be modified to an online fully remote tournament and would also include remote skills matches.[63]
Role in pedagogyVEX Robotics competitions have been of interest to educators as a way of stimulating students' interest in hands-on learning, engineering, and computer programming. The Department of Engineering and Technology Education at Utah State University has created a Design Academy with a curriculum for teaching skills through participation in a VEX Robotics Competition.[64] In addition, VEX Robotics provides two other programs aiming to introduce these skills at an early age in the classroom: VEX 123, and VEX Go. VEX 123VEX 123 is a VEX Robotics program aimed to introduce basic turtle-style programming to young students in kindergarten through second grade. It uses a small round robot with a front, wheels, and an audio speaker (the '123 Robot'), which is programmed to drive around a plastic course using either a handheld wireless programming module (the 'Coder') or a mobile device (not included) with Scratch-based programming software. The course is modular and can be built differently to present different programming challenges. VEX provides multiple pre-prepared STEM Labs designed for different classroom settings, such as language arts and mathematics. The VEX 123 STEM Labs are "designed to provoke STEM thinking and spark creative problem-solving ideas."[65] VEX GOVEX GO is a robotics program that introduces robotics to students in third grade and upwards. GO is designed to be an affordable construction system for teaching the fundamentals of STEM through engaging, collaborative, and hands-on activities that help young students learn coding and engineering concepts.[66] References
