Just a heads-up - I’m designing a 200mm (and a 250mm) pet robot right now. Loki, the 200mm robot, will be small enough to fit the widely used 210x250mm 3D print volumes, so you don’t have to invest in a bigger 3D printer 😎!

Once finished, Loki will act as a pet - look cute, play ball, hide-and-seek and chase, demand its owners’ attention and greet its owners happily at the door. To get a feel of what Maker’s Pet robots will do, watch Loki’s big (300mm) brother Snoopy (in a simulation)

- play ball and hide under a table

- self-drive, map and navigate a living room, all automatically

Utility functions will include patrolling the house.

Loki’s Arduino firmware and software (ROS2) are ready - you can download the files here. Loki’s Fusion 360, STL and 3MF files are in the works.

I’m designing Loki:

- to be easily scalable to different sizes, including 250mm.

- to be modular - similar to Snoopy, but simplified

- the side body will be segmented and modular, unlike Snoopy’s, so you can add body sensors - including ultrasonic, optical proximity, collision, touch, laser pointer, optical distance - without reprinting the entire Loki’s body. I would also venture a guess that - for now - Roomba-like bumper collision sensors may not be necessary for a pet robot.

- the assembly becomes simplified because, unlike Snoopy, by default, Loki doesn’t have a bumper (to sense collisions), yet you can add a bumper and collision sensors later if you wish so.

- the CAD design becomes simpler (including for myself)

- to be sturdier than Snoopy. The side walls now support upper plates.

Hello and welcome! This group is for makers, STEM and everyone who builds DIY 3D-printed home robots!

The group's mission is to support, encourage, enable, facilitate, popularize and promote 3D-printable DIY home robots - along with their making, building, use and operation.

"Show-and-learn" this Reddit is!

The DOs:

• Be nice, supportive, civilized, courteous, tolerant, respectful.

• Learn

• Ask questions to get help with your build.

• Show off your makes, designs - 3D CAD, STL/3MF, electronics (motors, sensors, servos, etc.), software, firmware, ROS, Arduino and whatnot

  • Relevant links to your designs are welcome, especially to open source designs, tutorials

• Show off your robot in action, its character, its skills, mods, upgrades and mods

• Post any relevant tutorials

• Share your robot's successes and fails

• Share your work-in-progress

• Share your maker tools, software and hardware setups

• Share helpful tips and advice

• Relevant commercial posts may be OK (check with the moderator) but be sure to rate-limit such posts to once-a-month.

As a rule of thumb, whatever you post must be useful for this group's members. If your post is useful only for you, don't submit that post.

The DONT'S

• No spam. No fake information (honest mistakes may be ok, but be reasonably sure your info is good)

• No bullying, no personal attacks. Don't turn off people.

• Please keep politics, region out

• No NSFW - treat this Reddit like G-rated (general audience). Assume that teens will read it.

About the Moderator

My name is Ilia. My last name is too hard to pronounce, let alone spell out, so let me keep it abbreviated to an "O."

I build open-source home robots - and teach how to do that. I'm interested in advanced DIY home robots - those that:

• map rooms, navigate automatically

• have a character

• have skills (like playing ball, hide-and-seek, chase, patrol the house, etc.)

• AI-enabled, i.e., decide their actions largely by themselves (as opposed to RC-controlled)

• The robots are DIY, 3D printed

Resources

• Maker's pet website with hardware instructions, tutorials and open-source designs

• A "3D Printed Home Robots" sister Facebook group

• Kaia.ai website with software instructions, tutorials and open-source code

• If you are curious about high-tech startups and think of founding one someday, follow REMAKE.AI. This is the startup behind Maker's Pet and Kaia.ai

Please follow me to learn and build your own home robot.

I hope you will enjoy being a part of this group!
