Today, I made a port of my old rEmotion 1 Arduino Nano-based firmware to rEmotion 2’s Pico. I used the second core for the stepper motor. You can build it yourself using PlatformIO. The code is crappy, probably has to…

Manual for Building rEmotion
Just publish a manual for building the rEmotion platform: Try to build your own! Supporting software is in development. Error happened.
rEmotion 2 – For Everybody
I started the second iteration of my robotic module rEmotion. This time it will be more public and accessible. I’m making it for everybody: More updates and instructions soon! Error happened.
rEmotion – a Module with Visual Input and Output
After several months of experiments, I’ve decided to shape a new project called rEmotion. rEmotion is a hardware module with a robotic application in mind. The module represents a head with a display and a camera, allowing a robot to…
LeOn – a Toy for Cats
Here I’m sharing my results with a project I started last summer. I finished it in the winter but forgot to share the results, so here they are. The project turned out quite simple, but I think it’s pretty solid.…
LeOn, a Cat Companion. Architecture First.
With this post, I start my new robotic project. This project will have several important features: What is the project about? It is a cat companion. A simple robot that can move around, avoid big obstacles and move a stick…
Zakhar Brain Service
Yesterday I merged a big software update to the Zakhar’s Raspberry Pi Unit – brain_service. The update brings a service providing the robot’s status (network, OS status) and access to the CAN bus for many simultaneously connected clients. Also, the service…
The Wheeled Platform with CAN support is merged!
A new step in Zakhar’s global transition to CAN bus is done! n n The unit consists of: It can be controlled via CANbus, Serial and Bluetooth. The documentation page is available here: https://zakhar-the-robot.github.io/doc/docs/systems/motion/wheeled-platform Error happened.
New Zakhar Face Module
The new Unit is based on the ESP-Wrover-Kit and uses a TJA1050 module for CANbus communication. It is compatible with the qCAN protocol (described on the Zakhar main page) and can show 5 facial expressions: Anger (0x32), Sadness (0x34), Pleasure…
CAN Bus and a New Simple Protocol
Not Only Two Wires It’s been more than two years already since I started working on my robot Zakhar. The Zakhar 1 was built out of Lego and relied on I2C communication between modules. It was a nightmare because as…
