The nameless engineer behind the Equals Engineering YouTube channel has proven off an uncommon sugar-cube dispenser — which makes use of OpenCV to focus on your espresso cup and mechanically fling sweetness in the appropriate course.
“I made an auto-aiming sugar-launching robotic that detects espresso cups and shoots sugar cubes into them,” the host of Equals Engineering explains. “The advice is to launch the sugar earlier than you set the espresso in!”
The center of the system is a Raspberry Pi 4 Mannequin B single-board pc, geared up with a digicam linked to the OpenCV pc imaginative and prescient library. It is this which is given the job of detecting espresso cups — or quite, to simplify issues, a single particular espresso cup: The most important pink object in its field of regard.
“To get the cup in the midst of the body it makes use of two wheels to wiggle itself backwards and forwards,” the robotic’s creator explains. “To measure how far to launch the sugar cubes it makes use of an ultrasound sensor.”
Launching the cubes reliably, nevertheless, took slightly doing: The mechanism is managed through two servos, one in every of which controls a hook and the opposite a compressed spring — the discharge of which propels a dice on its path to the cup

“There are fairly a couple of components on this little factor and one thing is certain to interrupt finally,” the maker admits, “so I made a take a look at sequence, to ensure all components are working independently, that i can run when one thing goes improper. It assessments all of the motors, the ultrasound sensor, and the digicam in sequence.”
A full video detailing the construct, together with loads of goal apply, is now obtainable on the Equals Engineering YouTube channel.
