Petoi Bittle Robotic Canine Evaluate Ranking


The Petoi Bittle is a wonderful mission for anybody that has a selected curiosity in robotics and programming. It’s extra superior than competing STEM robots with a steeper studying curve, however I feel it has the potential for a extra rewarding expertise.

Again once I was a child, the Web didn’t exist as we all know it, and the closest factor to enjoyable STEM initiatives I skilled was studying to program BASIC on a BBC Micro.

I feel it’s superb that kids as we speak have entry to such a variety of enjoyable studying sources.

The Petoi Bittle is a robotic canine that may both arrives pre-built, or you possibly can assemble it as a part of the educational course of.

It makes use of Arduino to manage all of the servos, and you might be taught find out how to use Arduino IDE to add its fundamental configuration. From right here, you possibly can then program the robotic utilizing both CodeCraft (scratch-based) or through C/C++/Python.


I used to be despatched the Bittle in its disassembled kind as I believed constructing it will be a part of the enjoyable. There’s a video on-line that guides you thru the construct course of. This was fairly easy, and I accomplished it in a bit over 30 minutes.

My equipment arrived in another way than what was marketed. It seems to be like Petoi has simplified issues a little bit by pre-assembling the physique and legs. Wanting on the guides on-line, I’m glad they’ve finished this because the legs look fiddly to assemble and never notably satisfying.

Due to this fact my equipment was principally attaching all of the cables and servos.


A bit embarrassingly, I discovered issues get much more complicated in relation to the preliminary calibration and programming of Bittle, particularly contemplating I’ve a level in computing. In my defence, I haven’t finished something like this in 10+ years.

I feel the principle concern I had was the general written documentation wasn’t as simple as I’d have preferred.

Just like the preliminary construct, there are supporting movies which do appears to assist fairly a bit.

You must set up the Arduino IDE after which the assorted libraries which might be accessible inside Arduino. You then have to remark out elements of the libraries for the IRremote because the Bittle doesn’t have sufficient storage for this.

You then want to put in further libraries and the OpenCat code from Github. Lastly, you have to join the Bittle to the PC with the uploader board and set the assorted ports so you can begin importing.

I feel my principal concern was that it didn’t appear that user-friendly for somebody with restricted expertise with all of the software program you might be utilizing. Whereas the directions had been laid out step-by-step, it wasn’t at all times clear precisely what I used to be doing.  

Utilizing the movies and the discussion board I did ultimately get there. I’ve solely finished the fundamental setup to date, however I intend to hold on utilizing it and see what else I can program it to do.

With this being aimed toward 14+ 12 months olds, I feel the directions might be padded out with higher supporting documentation. Although it’s fairly doubtless that your common 14-year-old has extra up-to-date programming expertise than myself.

So far as programming goes, you should utilize C/C++ or you possibly can simplify issues through the use of CodeCraft through the cellular app, which is scratch primarily based.

Extra Sensors

You may prolong the performance of Bittle with further {hardware}. The principle one can be the Clever Digicam Module which may then be used for clever object detection.

Below the Extensible Modules documentation, there’s additionally a variety of suitable fashions that may be clipped into the pinnacle of Bittle.

Some examples embody:

  • Sound Sensor
  • Gentle Sensor
  • Contact Sensor
  • PIR Sensor
  • OLED Show

The documentation additionally covers putting in a Raspberry Pi. Pi 3A+ which may then be used because the grasp controller

Value and Various Choices

In case you purchase direct, the Petoi Bittle is at present $279, decreased from $329. Within the UK, on Amazon, that is priced at £299.99 or £10 extra if you need it pre-assembled.

The clever digicam mannequin is an additional £60.

There’s additionally the Nybble robotic cat which makes use of wood elements as a substitute of plastic, and this prices $237

There’s a variety of STEM robots for youngsters and adults alike.

The Anki Vector and Cozmo was a very cute however costly AI robotic. The brand new Cozmo 2.0 is fashionable sufficient that it’s on again order till Q3 2022.

There’s additionally the Clicbot which is aimed toward adults and kids from ages 8.

The Freenove Massive Hexapod Robotic Package is maybe among the finest different choices for a extra superior mission. This may require a Raspberry Pi that are laborious to pay money for in the mean time and add to the fee considerably.

Wanting on the numerous different choices, I’d say the Petoi Bittle is extra superior; will probably be tougher to be taught, but it surely ought to educate extra sensible programming for youngsters (and adults) because it covers C/C++ and python.


General, I feel the Petoi Bittle is a wonderful mission for anybody that has a selected curiosity in robotics and programming. It’s extra superior than competing STEM robots with a steeper studying curve, however I feel it has the potential for a extra rewarding expertise.

At £300, it does really feel fairly costly, but when I had a child, and it helped them get into programming, I’d say it’s price it.
