Expand the horizons of your TETRIX® PRIME R/C Robotics Set. Engineer bigger, more advanced robots, increase the robustness of builds, and combine all the TETRIX PRIME components using the additional parts and pieces included in the TETRIX PRIME Expansion Set.

The TETRIX PRIME Expansion Set comes with three major parts that will provide students more design options for their robots.

  • Aluminum linkages – Mechanical linkages connect to manage force and movement.
  • Aluminum plates – Create custom gearboxes, strengthen connections, or create new ways to connect and combine all the TETRIX PRIME components.
  • Aluminum gussets – Use to connect beams or structural components as well as provide additional strength to joints.

TETRIX PRIME parts and pieces are made from aluminum and plastic.

“The PRIME building elements are easier to use, the connectors are larger, and the components are less prone to coming apart under stress. This encourages students to brainstorm more responses to challenges more quickly.”

– Ron Wright, retired teacher, Camas, Washington

“It really is realistic and that’s, I think, one of the main benefits to using the TETRIX PRIME system is that it really did give our kids exposure to more realistic constraints.”

– Jonathan Gaines, instructor, University of South Florida/Bulls Engineering Youth Experiences (Bulls-EYE)

“The TETRIX PRIME parts worked really well. Before we did the program, we did some test runs and discovered that, because several of them have dexterity issues, using screws was difficult for them. And we didn’t want it to become a frustrating thing.”

– Ivonne Torres, former Sunset High School (Dallas) senior working with special-needs students on robotics
