Quadruped robot made entirely out of cardboard

Walking robots can be a lot of fun, but many people would logically think that they need CNC equipment or a 3D printer to make this sort of bot. Creator “Raz85,” however, shows that this isn’t actually required, and built a quadruped using a structure comprised entirely out of corrugated cardboard.

Each of the four legs are driven using 9g micro servos, controlled by an Arduino Nano. A human operates the spider-inspired robot with a remote consisting of an Arduino Uno and a small joystick module, while pair of NRF24L01 radio transceivers provide a link between the robot and controller.

Despite its simple construction, the quadruped moves around impressively well…
