Robotic collects ping pong balls after matches
January twenty third, 2023—
In case you frequent driving ranges, you’ve most likely seen a machine (typically hooked up to the entrance of an armored golf cart) designed to choose up golf balls. As a result of a driving vary can simply refill with 1000’s of golf balls an hour, such machines are crucial. After noticing that no person needed to choose up the ping pong balls after matches, Maxime Monsieur and his staff (Oumaima Achkif, Reda El Marsse, and Amir Farbod) constructed this robotic that collects ping pong balls utilizing a mechanism just like these used for golf balls.
Like a golf ball amassing machine, this robotic picks up golf balls utilizing a spinning mechanism that resembles one thing you’d see on an agricultural harvester. Any ping pong balls in entrance of the robotic get pushed in direction of that mechanism by a pair of spring-loaded arms. The rotating mechanism then pushes the ping pong balls up a ramp and right into a bin. The robotic navigates by means of the room like an outdated robotic vacuum: by driving ahead till it meets a wall, then handing over a random course.
The staff constructed the robotic’s body and physique utilizing a mix of laser-cut MDF and 3D-printed plastic elements. It has two stepper motors that spin the 2 drive wheels, and a DC motor that spins the gathering mechanism. An ultrasonic sensor detects partitions and different obstacles. An Arduino Uno board controls the 2 stepper motors by way of A4988 driver boards and turns the DC motor on by way of a relay module.
In assessments, this robotic appears to work fairly nicely, although its navigation is inefficient. No phrase on if close by gamers try to pelt the robotic with ping pong balls as it really works.
