The T-Bot® II is a great project for illustrating hydraulic power and mechanics. See how syringes, tubes, and water work together to power the parts of this robotic arm. Each control moves one of the T-Bot II’s axes. The four controls can be used one at a time or all at once by a team of students – they can try basic maneuvers or moving objects as a team-building exercise!

The T-Bot II can be used for a range of ages and educational concepts – from showing third graders how to work together to helping college students explore load and effort forces.

“I’ve always been more of a traditional teacher, and this [using the T-Bot® II to teach Algebra 2] got me out of my comfort zone. But this generation of kids, if you do not make that application, they’re doing it just because I’m assigning it. So now they’re making the connection. . . . They have something to tie it back to.”
