This robotic arm is an easy to make 3-dimensional model that grabs, lifts items horizontally, and can turn very close to 90 degrees! Designed to be used alone (with a nice syringe holder), or in a group – each person using one syringe. A great way to learn about Robotics, Levers and Simple Machines, Fluid dynamics, Engineering, Invention, Design and Technology – or just moving things around the house. (Small things, mind you – no dogs or cats, please.)
