“Many of our students are beginners, and the various parts make it easier for them to do quick builds. The varied parts and the instruction guide [that comes with TETRIX sets] lead them in learning how to build a robot, and the students can customize their robots easily because of the standard holes on the channel bars and plates.”

– Thomas Lao, technology teacher, Macau Pui Ching Middle School, Macau, China

“TETRIX systems are easy for our students to use. Also they are well made and hold together better then a lot of the other robotic kits that we use. TETRIX makes a great product that is well built to last longer than our other robotic kits that we purchase.”

– Eric Franz, CTE technical support, Yakima (WA) School District

“The best strength of TETRIX, I believe, is the amount of different products offered.”

– Molly Powers, former junior at Saint Gertrude High School (Richmond, VA) and former member of Team CLUTCH. They used various TETRIX MAX parts to create a moving, speaking girlbot for Girls’ Lounge.
