Supercon 2023: Cuddly Companion Bots

October 30, 2024 by 4 Comments

Even in the advanced world of 2024, robots are still better in science fiction than in reality. Star Trek gave us the erudite and refined Data, Rogue One gave us the fierce yet funny K-2SO, and Big Hero 6 gave us the caring charmer named Baymax. All these robots had smarts, capability, and agency. More than that, though—they were faithful(ish) companions to humans, fulfilling what that role entails.

The thing is, we’re not gonna get robots like that unless somebody builds them. [Angela Sheehan] is a artist and an educator, and a maker—and she’s trying to create exactly that. She came down to the 2023 Hackaday Supercon to tell us all about her efforts to create cuddly companion bots for real.

DIY Baby MIT Cheetah Robot

July 5, 2020 by 7 Comments

3D printers have become a staple in most makerspaces these days, enabling hackers to rapidly produce simple mechanical prototypes without the need for a dedicated machine shop. We’ve seen many creative 3D designs here on Hackaday and [jegatheesan.soundarapandian’s] Baby MIT Cheetah Robot is no exception. You’ve undoubtedly seen MIT’s cheetah robot. Well, [jegatheesan’s] hack takes a personal spin on the cheetah robot and his results are pretty cool.

The body of the robot is 3D printed making it easy to customize the design and replace broken parts as you go. The legs are designed in a five-bar linkage with two servo motors controlling each of the four legs. An additional servo motor is used to rotate an HC-SR04, a popular ultrasonic distance sensor, used in the autonomous mode’s obstacle avoidance mechanism. The robot can also be controlled over Bluetooth using an app [jegatheesan] developed in MIT App Inventor.

Overall, the mechanics could use a bit of work — [jegatheesan’s] baby cheetah probably won’t outpace MIT’s robot any time soon — but it’s a cool hack and we’re looking forward to a version 3. Maybe the cheetah would make a cool companion bot?

Humanizing Industrial Robots By Sticking A Jibo On Top

May 25, 2019 by 5 Comments

A great many robots exist in our modern world, and the vast majority of them are highly specialized machines. They do a job, and they do it well, but they don’t have much of a personality. [Guilherme Martins] was working on a fun project to build a robot arm that could create chocolate artworks, but it needed something to humanize it a bit more. Thankfully, Jibo was there to lend a hand.

For the uninitiated, Jibo was a companion robot produced by a startup company that later folded. Relying on the cloud meant that when the money ran out and the servers switched off, Jibo was essentially dead. [Guilherme] managed to salvage one of these units, however, and gave it a new life.

With the dead company unable to provide an SDK, the entire brains of the robot were replaced with a LattePanda, which is a Windows 10 single-board computer with an integrated Arduino microcontroller. This was combined with a series of Phidgets motor drivers to control all of Jibo’s joints, and with some Unity software to provide the charming expressions on the original screen.

With the Jibo body mounted upon the robot arm, a simple chocolate-decorating robot now has a personality. The robot can wave to humans, and emote as it goes about its day. It’s an interesting feature to add to a project, and one that certainly makes it more fun. We’ve seen projects tackle similar subject matter before, attempting to build friendly robot pets as companions. Video after the break.
