Description Build your own robot boxing match with this hands-on hydraulics STEM kit. Construct two fully posable boxing robots powered entirely by water — no batteries or motors required. Each robot features complex shoulder movement, jab and uppercut punches, and interchangeable heads, so you and a friend can go head-to-head using handheld hydraulic controllers. Along the way, learn the real-world engineering behind hydraulic systems, gears, cylinders, and pistons. A action-packed STEM building kit that combines robotics, physics, and head-to-head competition.
