Meet Bittle, an Advanced Open-Source Robot Dog by Petoi

[@corneliu2544]

Looks awesome. I think this may be a perfect anniversary gift for my 13 old son.

[@ImMajesticAf]

This looks awesome, honestly the first thing that popped into mind is, having a sensor be it a gpu or bluetooth sensor, for it to detect a bed, and having it climb onto it when its low on battery, both would also have a wireless charging setup, the idea sounds cool but lord knows I can't do anything like that yet 😂

[@MichaelKlements]

Some sort of wireless charging when it "returned to bed" would be an awesome addition to try.

[@mywschool8910]

It is doable of course.

[@daveallan3152]

Great overview, thanks. Where can I get plans for the test stand?

[@jacocoetzee762]

What a great project! Thanks for sharing!

[@AlixFlemmer]

This is so cool I feel like the possibilities with it are endless

[@eljangoolak]

Can it eat its own head? I didnt think so!

[@blackmennewstyle]

Nice project, the servos are the ultimate limitation i think but probably an interesting plateform to play with :) Have a great weekend

[@MichaelKlements]

They've used good quality servos, they're all metal geared and quite responsive - but yes they are just servos, so they have got limitations.

[@robert36902]

First reaction: I must have it NOW. Preferably to assemble myself. I've always liked the Boston Dynamics Spot videos, and this actually looks like an affordable mini version. Second reaction: Couldn't they have designed a hole for the programming modules to be connected and disconnected without having to remove the back and bend that connector over and over again?

[@robert36902]

I ordered one, thanks for the 10% discount code :D

[@MichaelKlements]

Yeah it would be nice to have a secondary back cover that would allow the additional modules to fit and potentially even hold a Raspberry Pi in place over the board.

[@testthingamajig-zr2no]

question, is it easy and non damaging to physically remove the head from the petoi bittle with a screwdriver and or other tools?

[@diegobernal4565]

from italy , very good

[@tiagotiagot]

Do the servos provide any info about their current position and/or current draw and stuff like that, that could be used to have the legs double as mechanical sensors for more advanced behaviors?

[@MichaelKlements]

They're standard hobby servos, so don't provide any feedback to the controller. The controller just provides them with a position reference and it's left up to the servo to follow the input.

[@Sportsman134]

Could you share your 3d print design for the holder?

[@MichaelKlements]

The holder is not my design, it is also from Petoi. It's available from their Github repository - github.com/PetoiCamp/NonCodeFiles/tree/master/stl/BittleStand

[@sayax4464]

Hello I have my project defense next week and I need help on a program to monitor the battery (lithium polymer 3.7v) and indicate if it is discharged by indicating the percentages, using arduino

[@RahulVanjeri]

Use voltage dividers with high resistance to minimize current and use ADC to measure the levels

[@TheCartographer89]

Is there any self learning code out there to upload to it? Attaching speakers, cameras and thermo sensors would be neat if you could train it like a dog to do tricks and talk to you. Also little shoes could be useful.

[@MichaelKlements]

Self learning requires a lot of processing power, you can't run this directly on the microcontroller. It does however have the facility to plug it into a Raspberry Pi or a Jetson Nano and you could then use these for self learning applications.

[@ivyward6152]

I want one so bad!

[@rvignesh2809]

The discount code Michael10 is not working

[@tiagotiagot]

Can it be reprogrammed to use the IMU more actively, for full self-ballancing and more organic movements? Does the processor got the performance required for such real-time motion tweaking?

[@MichaelKlements]

Yes the onboard microcontroller is programmable and open-source so you can add your own tweaks to the software to make improvements. If the onboard microcontroller doesn't have the capacity, you can also interface something like a Raspberry Pi to it to offload some of the processing.

[@donpage4326]

Can you post the 3D printer file for the stand? Thanks Respectfully Donal Page

[@MichaelKlements]

It's available from their Github repository - github.com/PetoiCamp/NonCodeFiles/tree/master/stl/BittleStand

[@aboverobotics]

In Oct. 2024 I am surprised it is open source and made 4 years ago!

[@OliverHoerold]

Cool platform for AI I think

[@MichaelKlements]

Yes, if you pair this with a Raspberry Pi using the included pin headers you'd have quite a powerful platform to work with

[@colbybaker4651]

Is he weather proof?

[@MichaelKlements]

His electronics are somewhat protected with plastic covers but I wouldn't leave him out in the rain

[@noobieza0077]

Very cool el psy congroo

[@fahrimertdincer8421]

Steins gate

[@tarniayres]

Omgg its axl

[@partsdave8943]

Cool little toy. Perhaps you could 3D print some larger feet (shoes) for it. Something like PLA, or PETG, with a flexible piece on the bottom. Could use TPU, or even off the shelf, adhesive rubber pads. That should help with navigating rougher terrain like the pebbles.

[@MichaelKlements]

That's a nice idea to try, thanks for the suggestion

[@wgemini4422]

Rather expensive for essentially an arduino board plus maybe 10 servos and a few sensors. You also cannot build anything else with it.

[@MichaelKlements]

They have made the design and software open-source, so they encourage people to make their own if they don't want to buy a pre-built one.

[@unperrier]

It feels like gadget, really.

[@MichaelKlements]

All of these sorts of projects are a bit like a gadget, I like that this is open-source though so you can develop it further and spend some time making it you own.

[@ClassifiedName_VR]

Bittle is to expensive my mom wont let me get it:(😭😭😭

[@smithwill9952]

We need Spot or Unitree, not a Toy.
