Design and build a real working animatronic machine with Think Box Hydraulic Robotic Arm! Learn the basics of physics and engineering as you learn to put pre-designed wooden pieces together to create a robotic arm. Watch how the use of fluids create movement using a pressurized plunger and flexible tubes. Many different systems are created with hydraulic technology. Get inspired and research how hydraulics were sophisticated power systems in ancient times and a major part of engineering science.
