Building on an earlier design created back in 2014 developer and maker Jose Julio has upgraded the air hockey robot with a new camera and processor which has been provided by a new smartphone upgrade.
The smartphone is used by the robot for eyes and brain power and has been combined with a number of different components such as an Arduino, an ESP8266-based shield, NEMA 17 stepper motors, stepper motor drivers, as well as some belts, bearings, rods, to create a fantastic air hockey opponent which is sure to test your skills to the max.
Check out the video below to learn more about the new upgrade and how well the air hockey robot can play.
Air hockey is a classic arcade game consisting of two players, two paddles, a puck, and a low-friction table. But what happens if you don’t have an opponent? If you’re Jose Julio, you build a robotic one out of 3D printer parts.
The smartphone’s camera is looking at the playing court. The camera’s captured data is processed in real-time by the smartphone. Detecting the position of the puck and the “pusher robot” (and according to the current location of all the elements on the court), your smartphone makes decisions and commands the robot what to do via Wi-Fi.
Your smartphone will become an augmented reality device, showing predicted trajectories and position of all the objects involved in this game.
