The BBC has a behind the scenes story on the various robots used to package our food:
Last July, while touring a jelly bean factory, I came upon a startling sight. Over a conveyor belt, a large robot spider danced over packets of sweets, plucking each one up with human speed and precision and placing it in a carton. The packets were piled willy-nilly, but the machine and its colleagues – two others were also manning the line – seemed to know where each one was and worked together to collect them all in seconds. It was riveting, and not a little eerie.
It turns out these robots are based on a design by Swiss robotics professor Reymond Clavel of the Ecole Polytechnique Federal de Lausanne, called a delta robot. They are incredibly quick and can do jobs in food packaging that only humans used to be able to do, like sorting or stacking randomly arranged objects, without the repetitive stress injuries such tasks give people.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
