          • Mark T. — STEM Educator

            Built the 6DOF arm with my robotics class. Students were engaged for weeks. The metal construction makes it feel like real engineering.

          • Jason R. — Arduino Maker

            The metal construction is no joke — this thing is solid. Arduino integration was straightforward. Great value for the build quality.

            My 12-year-old built the 4DOF kit in one afternoon. Now he wants the 6DOF. Best STEM investment we have made.
