Starting a robotics competition team can seem overwhelming, but it’s not as scary as it seems. Here’s a high-level overview of what you need to do to get a team up and running:
- Choose a platform
Now more than ever, robotics teams are faced with the important question of which platform they should purchase and use. LEGO and VEX are the two most widely used platforms. LEGO is primarily used for elementary through middle school (Ages 9 – 14), while VEX can be used for kids in elementary school through college (Ages 8 – 18+).Whether you choose LEGO or VEX, Robomatter has the resources you need to make your team successful, including hardware, software, free curriculum to help students learn to program, and training to help you get things up and running.
- Pick your equipment
Once you’ve chosen a platform, the next step is to pick your equipment. Whether you’ve decided to go with VEX or with LEGO, Carnegie Mellon’s Robotics Academy has a great resources page to provide you with all of the tools and information you need to get started.You can access the VEX page here and the LEGO page here.
- Choose your software
ROBOTC is a C-based programming language with a Windows-based environment for writing and debugging programs. It’s also the most used language for the VEX IQ Challenge, and for the VEX Robotics Competition. ROBOTC is the only solution that offers a comprehensive, real time debugger. It also comes with a Graphical interface, which is a great way to get new students started.In addition to ROBOTC, you may also want to check out Robot Virtual Worlds, a high-end simulation environment that enables students to learn programming without a physical robot. With Robot Virtual Worlds, students can develop and test code on a simulated robot before running code on a real robot. They can also work on the robot when they’re at home, which means they don’t need to be in the classroom to prepare for the competition. With Robot Virtual Worlds, VEX users can also take part in online competitions.LEGO users can use Robot Virtual Worlds by adding on the Virtual Brick. By looking and acting like a LEGO Brain, the Virtual Brick allows teams to program virtual robots using the same programming language as they use to program real LEGO robots.
- Identify your technical and logistical requirements
Here are some things you’ll need to think about:
- Computers: You’ll want to have one computer for each robot/team of students.
- Practice Area: The space should be large enough to accommodate the team, computer, practice table, and storage area for the robots.
- Parts storage: To keep parts organized and accessible, parts organizers are a must. There are many options – portable organizers, drawer cabinets, boxes, caddies, etc. These are readily available online and at local hardware and craft stores.
- Network – The software will need to be loaded on each computer or available via the network on each computer. Programs should be included in the regular system backup or a leader should make a backup to a separate disk or memory stick.
- Prepare a budget and get funding
Your budget will need to take into account:
- Robot kits and pats
- Parts organizers
- Miscellaneous tools, parts, and supplies
- Competition entry fees
- Travel expenses, including gas, food, and lodging
- Team shirts or other items to promote your team at the event
Some potential sources of funding include your school district, local businesses, and local non-profit organizations. You may also consider having a fund raiser, like a bake sale or car wash. Be sure to acknowledge your sponsors at every opportunity, such as printing their names on your team shirts, etc.
- Build your team and assign rolesIn terms of team size, we’ve found that first-time coaches typically do well with about eight students. For larger teams, or if you have the resources, recruit other mentors for your team to lead the subgroups.Once you’ve built your team, the next step is to define roles. We recommend having students change roles on a regular basis, allowing them to share responsibility for all aspects of building, programming, etc. These are the roles we recommend:
- Engineer (Builder)
- Software Specialist (Programmer)
- Information Specialist (Gets the necessary information for the team to move forward)
- Project Manager (Whip-cracker)
- Plan, build, test, and iterate Once you have your equipment, funding, and team in place, you’re ready to get started!To make your team most effective, it’s a good idea to stick to a schedule. Create a schedule that fits your team’s objectives and resources. When you’re ready to build your robot, be sure to familiarize yourself with the competition rules and requirements. If you have questions, reach out to the community for help. There are a lot of great forums out there, such as the ROBOTC forum.Remember, an important part of the process is testing and iteration. Make sure your team knows it’s going to take time to get it right. Luckily, both the VEX and LEGO platforms allow teams to quickly build, test, iterate, and repeat. Even still, students may get frustrated by this process. Remind them that building, programming, and testing a robot doesn’t always go as planned. But, even though a design may have failed, it’s still a valuable learning opportunity, with lessons that can be applied to the next time you try.

The Robotics Education and Competition (REC) Foundation is pleased to announce the winner of the 2015 Robomatter Scholarship, valued at $5,000 which invited students participating in the VEX Robotics Competition to submit an essay explaining how their participation in both the VEX Robotics Competition and the Carnegie Mellon Robotics Academy sponsored Robot Virtual World Competition enhanced their understanding and application of programming. In addition, students were encouraged to share how programing skills and use of ROBOTC improved their robotics experience.
“It’s rewarding to hear that students, like Max Farr, gain valuable hands-on experience in programming through participation in the VEX Robotics Competition,” said Jason Morrella, president of the REC Foundation. “The REC Foundation is extremely grateful to partners, such as Robomatter, who make it possible for students to secure the resources they need to continue their education and pursue a post-secondary degree in STEM.”
The winner of the 2015 Robomatter Scholarship is: Max Farr, VEX Robotics Competition Team 21, from CHAMPS Charter High School in California.
“As our team’s driver and programmer, I rely on ROBOTC’s easy and approachable format to enable me to quickly plan, set up and execute commands that improve our game strategy and overall execution,” said Max Farr. “I also rely on Robomatter’s Virtual World at the beginning of every season to better understand the game and quickly begin brainstorming robot designs.”
The 2015/2016 season is now open with VEX IQ Challenge Bank Shot and VEX Robotics Competition Nothing But Net. Both games are available through the Robot Virtual Worlds too!
The Robot Virtual Worlds team is thrilled to announce the availability of two brand new virtual environments, the VEX Robotics Competition – Nothing But Net and VEX IQ Challenge – Bank Shot Robot Virtual Worlds. As in years past, these worlds were made available at the same time as their real world counterparts were unveiled at VEX Worlds!
The competitions for this year are both extremely exciting; teams will actually need to shoot balls into goals. The purpose of these virtual environments is to provide teams with an environment that allows for some strategic planning, and to act as a platform to start programming with the same kinds of motors and sensors that are available in the real world. To that end, we’ve added exciting new “Launchbots” that are capable of shooting balls across the field and are fully programmable with a full array of motors and sensors. One feature we’re really excited about is the “trajectory line”, which shows exactly where your shot will go based on the robots angle and motor power! Game scoring, timing, pre-loads, match loads, climbing, and other elements are all implemented, too.
Check out our video of the VEX Robotics Competition – Nothing But Net RVW in action:
And here is footage from the VEX IQ Challenge – Bank Shot RVW:
To help you get started with these new Robot Virtual Worlds, we are providing a FREE summer license, available at: http://robotc.net/vex/. Our video-based VEX IQ Curriculum is also available completely for free to help you get started with programming.

Executive director of China ROBOTC, Terry Sy, shares their latest robotics competition adventure with us from the 2014 Asia-Pacific Robotic Championships. Read about it below …
The Asia-Pacific Robotic Championships 2014 were held in Dongguan, China from December 1st to December 4th. The first time in its history, China ROBOTC took 4 teams down there to compete. Among those making the trip down to the southern city were a China ROBOTC VEX team, Qingdao ROBOTC Boca Primary School team, Qingdao ROBOTC Boca Secondary School team, and ROBOTC-Experimental Primary School team affiliated to Shaanxi Normal University.
All the team members had a great time, competing in both the VEX and the VEX IQ competitions. Many new friendships were forged and the fantastic experience will be cherished by all those who took part for many years to come. But our teams weren’t just going down there to make friends and have fun. They had come to challenge for the championships.
Altogether, the teams had a lot of success in their respective competitions. In the VEX IQ programming skills competition, one of our primary schools took first place, while the other was a close runner-up. In addition, our secondary schools joined the primary school with a first-placed finish. Meanwhile, in the team competition, our elementary school and secondary school both finished in the runner-up position. As well as this, one member from the primary school and one member from the secondary school excelled in the robot skills competition, both taking 2nd place, and they also received 3 gold awards in IQ and an inspire award in VEX to cap off a fantastically successful event.
Well done to all those students who took part, and keep up the good work!
