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, and Invention, and Design and Technology.
Easy to make in about an hour or two, it stretches 49 cm (16 inches) out, swings 18 cm (7 inches) around, and stands 37 cm (13 inches) high.
Precisely cut and ready to assemble with timber slot construction.
Best of all: no batteries required!
