• Handmade: Each joint is built by the player and finally assembled into a dinosaur boxer. Triceratops/Tyrannosaurus Rex can be freely chosen and the driving force is provided by a handmade hydraulic system
• Assembly and Principle: Learn about the physics, design and components of hydraulic (water) mechanisms, including gears, cylinders and pistons.The upper and lower bodies move independently to simulate real movements, allowing these boxing robots to dodge, jab and punch accurately
• Perfect Control: The left and right hands control the upper body's fist swing and the movement of the leg joints respectively, allowing you to have the best control over the robot and easily perform fighting techniques such as blocking, straight punches, uppercuts, etc. Shake the handle to dodge, squat and stand, providing you with the strongest defense
• High-quality materials: The fighting set includes two dinosaur boxers, two control handles and a scoreboard, which is very convenient for recording fighting scores; all parts are made of high-quality ABS, which is non-toxic and odorless, and children can assemble and play safely
• Gift Choice: This scientific teaching aid is suitable for all children and teenagers who like to do it themselves. It can be made independently or with the help of friends
