In the future, we will be 3D printing flexible and dynamic robots to perform complex tasks. In fact, MIT’s CSAIL researchers have demonstrated a technique to 3D print robots using solid and liquid materials at the same time. These hydraulically-powered robots require no assembly.
As the researchers explain, you will need a battery and motor to have your robot walk right out of the printer:
researchers 3-D printed a small hexapod robot that weighs about 1.5 pounds and is less than 6 inches long. To move, a single DC motor spins a crankshaft that pumps fluid to the robot’s legs. Aside from its motor and power supply, every component is printed in a single step with no assembly required.
MIT has more on the story.
