It doesn’t promise to taste great or to be less filling, but Attiny Canbot sure is cute.
This project springs from the mind of Thingiverse contributor Maxmillian Kern, who goes by the pseudonym ‘Wingman94.’ In a nutshell (or in a can) the creature is a cylindrical robot that rolls its way across surfaces at the instruction of an Atmel Attiny85 microcontroller. 
The commands are received via an infrared signal sent from a modified remote control for television. For those who would like a more hands-off approach to Canbot husbandry, the critter is equipped with an ultrasonic sensor for autonomous driving. This means you can give Canbot freedom to roam about your house and he won’t spend 20 minutes blindly butting himself into a wall.
Kern’s Canbot is a descendant of another diminutive mechanical dynamo he created two years ago, a bipedal robot with a face only its programmer could love. Recouping on the effort put into programming the Walking Wired, he recycled some of the code he had used and thus was born child-of-biped Tiny Canbot. While drawing on inspiration from the iPhone controlled Ollie Robot for the form, the design of the Canbot is sleeker and less kitsch.
In an interview with 3DPrint.com, Kern explained how he developed the robot:
“The design is functional. I basically just arranged the parts in CAD to find out what shape fits best. There are two printed half shells that hold the servos, battery, ultrasonic sensor and electronics. They are connected by four screws. Two printed wheels are screwed onto the servos heads. I used PTC Creo to model the parts, Slic3r for slicing and a Prusa i3 Hephestos from BQ to print them. The prints took about 3 hours for each shell and half an hour or so for each wheel.”
Not one to gloss over imperfections, Kern acknowledges that there are problems with the weight distribution in his cylindrical progeny. However, he has made a conscious choice not to engage in body shaming his offspring and doesn’t plan to make drastic changes because the robot is still fully functional.
In the spirit of sharing, Kern has released the files for the minuscule marauder on Thingiverse so that others can create their own army of rolling creations – technically known as a ‘fluffle,’ I believe. Given that each creature takes between 8 and 10 hours to print, if you start now, you could probably be ready to take a few out partying this weekend. I’ve heard that’s what all the cool kids are doing.
