Computers and sensors are quickly decreasing in cost and size, making it easier than ever before to build smart gadgets or robots. From accelerometers to thermal sensors, electronics nowadays can detect and record a variety of events and objects in their surroundings. Here’s one more sensor to add to your robot overlord-in-training. It’s called Pixy, a camera that identifies objects through color.
Pixy was made by Charmed Labs and embedded systems experts from Carnegie Mellon University. It’s actually the team’s fifth version of a smart and low-cost vision sensor, which they previously called the CMUcam. What separates the Pixy from other image sensors is that it only sends a small amount of data and it has its own microprocessor. These traits make it possible to integrate the Pixy even to microcontrollers like the Arduino.
