If you happen to weren’t alive for it, you won’t understand how intense Tamagotchi fever received within the late ‘90s. As a licensed ‘90s Child, I can guarantee you that it was uncontrolled. Everybody I knew in my elementary faculty had at the very least one Tamagotchi and a number of the cool children had a number of of them. However I don’t recall seeing many grownup Tamagotchi pets, as a result of youngsters have brief consideration spans. With a purpose to lastly present Tamagotchi pets with indefinite high quality care, Jens constructed this nanny bot for the little digital critters.

It is a type of robotic that may work with any Tamagotchi within the authentic egg model, with out requiring any modification of the system. It’s going to responsibly watch the Tamagotchi pet from the time it hatches and all through its total life, feeding it and cleansing up after it as crucial. With none human intervention, it should present good care.

The most important problem right here was avoiding the necessity to modify the Tamagotchi — a route that Jens might have taken to make his life simpler. To make that occur, Jens wanted a method to work together with the Tamagotchi and a method to see its standing.

Interplay was simple. Jens designed a 3D-printable cradle for the Tamagotchi to relaxation in, with three servo motors to press the three buttons. However studying the display screen was trickier. Jens related a digicam to a Raspberry Pi and pointed that on the Tamagotchi display screen. He then used a pc imaginative and prescient script to detect the sprites.

That wasn’t as simple because it sounds, as a result of even small variations in lighting can throw off the detection. The character of a budget ‘90s LCD didn’t assist issues. However the silver lining was that there are solely a handful of doable sprites they usually’re all fairly easy. That permit the pc imaginative and prescient detect sprites with sufficient reliability for this software.

From there, it was a matter of programming a care routine. That took a variety of work, however Jens ended up with a robotic that may comply with a handful of guidelines to lift a Tamagotchi pet to maturity. If it detects poop, it presses the sequence of buttons crucial to wash that up. It may have a look at the metrics for well being and happiness, and act accordingly.
