ZeroBot is a Raspberry Pi Zero W based robot. It can be controlled using any computer or smartphone via a web browser. The integrated camera module makes for a low latency video stream. In addition the Raspberry Pi acts as a Wifi access point, so no router is required. The parts for the hull as well as the wheels can easily be printed on any regular 3D printer.

Some of the key features are:

  • Compact CAD design with 3D printed components
  • Analog control via a joystick (and multitouch)
  • Simple battery solution using only a standard power bank
  • Low latency streaming (~0.3s)
  • Easy and cheap to build using widely available components

Print the two shells with the inside facing the print bed. You will need to include a lot of support material. Simplify3D works best for this, but Slic3r or Cura with optimized settings should be fine as well. I used support with lower density for the most part and higher density for the last 8 layer up to the part. This saves a lot of filament.
The tires should be printed with Ninjaflex or something equivalent to ensure good grip.
Everything else can be printed in PLA.

I absolutely love this model and am working on printing one now. Is that a switch on the back side? I didn't see that in your parts list. Do you know what switch you used?

Glad you like it! Yes, that's the on/off switch. It measures 11.5 x 6 mm, but I don't have a direct link on where to buy it.
In case you haven't found it already, here is a link to the 3D model: http://a360.co/2rV2NQo

Do you think you can share the CAD files for easy remixing?

EDIT: Ignore this; saw the link to F360 on hackaday.

Nice project. Currently working on something very similar. Keep it up.

Can you post your settings for supports in S3D? With my settings the support material get fused with the part and I don't want to waste more filament on a bad print :/.

I added a screenshot of my support settings to the thingiverse page. I hope this helps!

I may be missing something, but the filler/camera mount. Is there a model or did you mention what you made it from someplace? This is really cool, and I am thinking of popping one together and letting some kids program on it to make it move and do stuff.

You are absolutely right, I forgot to export that part. It is online now.

Thanks... In the pictures, it looks like the same material you used for the tires. Sure it's not, but what filament do you use for the tires? Is it NinjaFlex, or is it one of the other TPE/TPU filaments?

Quote from the description:

you know the game rainbow six siege??
this looks like the twitch drone

Yeah, I've played the game during a free weekend. Indeed it looks a bit like my robot.
I might have to include shock darts in the next version. ^^

Most excellent model.

I think my kid and I will tackle this build next month. Any chance of getting a wiring diagram?

Thanks so much for so many awesome projects!

Thank you!
I hope that I will have a wiring diagram and a basic tutorial ready by the end of the week.

Wow, really nice and well made! Gonna make one with my son.
Is it possible to connect it to the home wifi or do you have to use it in adhoc mode? Would be really fun to control it over internet. Maybe it would be possible to add a login screen for security then.

Thanks! Connecting it to a wifi router is very simple. The adhoc mode is just an option.
Using it over the internet might be a bit more complicated.

Perfect. Aslong as it's possible to hook it up to home wifi I can VPN to my home network and connect to it. Shouldn't be a problem. Higher latency ofcource. But should be pretty straight forward.

So cool! How well do the printed wheels grip..perhaps a rubber band over them or maybe a groove for an o-ring for extra grip
Disregard..found this entry on your hackaday post: The wheels are designed to have tires made with flexible filament (in my case Ninjaflex) for better grip.

Very cool little robot and the fact it does it's own wifi ap is very neat

Great design and build!

Thank you, I appreciate it!
