Yes, it's the exact model of our production model. The previous one was reverse engineered by our users.

Cool! Have you tried the model at: https://github.com/PetoiCamp/ros_opencat/tree/ros1/petoi_ROS_model_docs/bittle_ros/bittle_description?

We now have a newer app for Bittle. But you will need to upgrade the firmware. https://docs.petoi.com/upload-firmware https://docs.petoi.com/mobile-app/introduction

Very nice job! Thanks for sharing! Could you add your GitHub link in the post? It's not in the video description.

I made an adjusted cover with a hole for the Pi. https://github.com/PetoiCamp/NonCodeFiles/blob/master/stl/BittleCover/Bittle_Cover_with_hole_for_Pi.stl

The petoi modules are designed to connect to the Grove sockets and be controlled by the mainboard by default. You can always use jumper wires to connect the modules to the Pi, with some voltage regulators. Showing some pictures of your modules and system configuration will be helpful to better understand your questions.

The smaller one is for Bittle and Bittle X directly shipped by us. The larger one was a older packaging by TinkerGen, a daughter company of Seeed Studio. The newer one allows you to put Bittle inside with the head remain attached. Did you get the package as pre-assembled or construction? The pre-assembled version has a interior support structure to keep the robot safe.

Bittle X has ESP32 that can run Wifi directly. We are working on a browswer-based coding interface that will build the communication channel. You can preview the page here: https://borntoleave.github.io/PetoiWebBlock/PetoiWebBlock/programblockly.html. Note that the system only works with a local version and will require our latest firmware with the wifi support. We will push a beta version to GitHub in a month.

Please send pictures of your kit contents so we can confirm if anything is missing.

Hi, make sure you're charging the battery via the battery’s port, not the mainboard. https://docs.petoi.com/technical-support/battery#charging

I showed the video to some researchers and they are very interested. Could you add English subtitles to the video?

The manufacturer has discontinued the product line and we only have a couple of them in the warehouse. You can write to support@petoi.com to order one.

Could you take a screenshot of your Esp32's settings?

We should have some in stock but not in every warehouse. You can write to support@petoi.com to request an invoice.

Yes. It's helpful to see what works then make modifications. https://www.petoi.com/products/biboard-esp32-development-board-for-quadruped-robot

Please check the comparison chart of the controller boards. The BiBoard V1 was developed recently and we haven't officially release it, and it will be slightly more expensive than the V0. It was only shipped out when some warehouse has no BiBaord V0 left.

I'm not sure. Different Esp32 boards may have different pin maps. That option works with BiBoard. https://docs.petoi.com/biboard/biboard-v1-guide

Yes, there're options for the BiBoard in the Firmware Uploader.

Do you have a video to show the strange movements? After uploading the firmware, have you entered 'Y' for the serial monitor's prompt for calibrating the IMU?

Arduino Nano uses ATmega328 as the micro-controller. Arduino Nano ESP32 uses ESP32 as the microcontroller. They are different chips from different companies. To run the ESP32 version, you need to use the OpenCatEsp32.
