RoboPlay Video Competition

RoboPlay Video Competition is a robotics-centric video competition for students in grades 5-12. It is designed for  students to learn robotics while having fun and exploring their creativity in writing, storytelling, art, music, choreography, design, video editing and film production, and at the same time seamlessly learning C-STEM subjects. The necessary robot coordination to match the movement of multiple modules to music requires not only teamwork in designing a well-organized visual performance, but also the math and programming skills to produce the desired actions. The competitions enable students with different interests to explore the basic concepts of C-STEM in conjunction with their artistic and music talents. A student of average skill should be able to reproduce a video with the documentation submitted for the video.


  • Division 1: Junior Teams with students from elementary and middle schools (grades 5-8)
  • Division 2: Senior Teams with students from high schools and community colleges (grades 9-12)


  • All team members must be enrolled in a K-12 school and from the same school anywhere in the world. However, each C-STEM GIRL camp can also submit one team video for the competition.
  • Each team must have 3 or more students contributing to the video. There is no limit on the number of team members.
  • Each teacher who advises the students can sponsor up to 5 team videos.

Equipment and Computer Programs: 

  • Linkbot accessories from Barobo, including Barobo Arduino and Barobo Raspberry Pi, are allowed, but not required.
  • Backgrounds, sets, and costumes are highly recommended, especially to stay competitive., but not required.
  • Only parts from C-STEM Center and Barobo are allowed. Custom-designed parts are encouraged.  Documentation for the custom-designed part must be submitted. If the part was rapid prototyped/3D printed, the CAD file(s) must be submitted. If the part was constructed without 3D modeling software, then blueprints, drawings or sketches must be submitted.
  • Motion of these robots must be controlled using programs written in Ch, a C/C++ interpreter in Windows, Mac OS X, or Linux in C-STEM Studio. You may use C-STEM Studio  in  C-STEMbian with free Ch for Raspberry Pi to create motions of Linkbot robots. Teachers may participate in a C-STEM Professional Development  or through on-line video tutorials to learn how to control Linkbot using C-STEM Studio.

Video Content:

  • The robot(s) and their coded movements must be critical to the video. All scenes should focus on robots as the primary figures.
  •  Each video must be between 1 and 5 minutes long.
  • All elements of the video, except music, must be produced originally by the students.


  • $20 for each submitted video for competition (No C-STEM subscription is required).
