Hydraulic Robotic Arm Working Wood Model KitLP0055
This robotic arm is an easy to make three-dimensional model that grabs, lifts items horizontally, and can turn close to 90 degrees. By using syringes for the hydraulics, the robotic arm can be used alone (with a syringe holder), or in a group with each person using one syringe.
A great way to learn about robotics, levers and simple machines and get to grips with some of the basic principles of engineering.
Easy to make in about an hour or two, it stretches 49cm (16 inches) out, swings 18cm (7 inches) around, and stands 37cm (13 inches) high.
Best of all: no batteries required.
