The pressure system in the 3 in 1 Hydraulic/Pneumatic Edge Robot allows for the application of both water (hydraulic) and air (pneumatic) power.
Following in the footsteps of award-winning products like the Air Power Racer and Hydraulic Arm Edge, OWI brings you a new kit that combines elements of the aforementioned products while adding new forms and functions for multiple layers of fun. With 3 in 1 Hydraulic/Pneumatic Edge Robot, children ages 6+, as well as adults with an affinity for building, can take this 54-piece kit and build THREE different models (at three different difficulty levels) that all utilize the power of air and water! No batteries or motor required! The detailed instruction manual will guide builders as they create a pressure-driven inchworm robot (beginner), dinosaur robot (intermediate), and even a robot arm (expert)!
