Raspberry Pi and Alexa Make Teddy Ruxpin Smarter than the Average Bear

Behold the unholy union of Amazon’s Alexa and that feature-limited animatronic bear from the 80s, Teddy Ruxpin. Alexa Ruxpin?

As if stuffing Alexa inside a talking fish weren’t bad enough, now Amazon’s virtual assistant can talk to you through the creepy retro plush thanks to [Tinkernut]’s trip down memory lane. Having located a Teddy Ruxpin on eBay for far less than the original $70 that priced it out from under his childhood Christmas tree, [Tinkernut] quickly learned that major surgery would be necessary to revive the Ruxpin. The first video below shows the original servos being gutted and modern micro servos grafted in, allowing control of the mouth, eyes, and nose via an Arduino.

With the bear once again in control of its faculties, [Tinkernut] embarked on giving it something to talk about. A Raspberry Pi running AlexaPi joined the bear’s recently vacated thorax with the audio output split between the bear’s speaker and the analog input on the Arduino. The result is a reasonable animation, although we’d say a little tweaking of the Arduino script might help the syncing. And those eyes and that nose really need to get into the game as well. But not a bad start at all.

This isn’t the first time that Teddy Ruxpin has gone under the knife in the name of hacks, and it likely won’t be the last. And the way toy manufacturers are going, they might just beat us hackers to the punch.

Hacking Teddy Ruxpin

[DJ Sures] got his hands on a broken Teddy Ruxpin doll and decided to give it a new robotic life. You may want to ask the children to leave the room before viewing the video after the break. It starts right off with little Teddy having his throat slashed in order to get at the parts in the head. After retrofitting the eyes, mouth, neck, and arms with servos, Teddy gets a Bluetooth upgrade that lets you control his movements wirelessly. [DJ Sures] even has plans to get the little guy up and walking, far exceeding the original capabilities.
