Hi everyone ! I'm a french robotics intern in France, and I'm currently creating a robotics course for children based on Petoi robots Nybble and MiniCat (and Bittle very soon). I've already posted my first course : Nybble doesn't like obstacles. Today I wanted to show you my MiniCat, with some OLEDs screens as eyes ! I find it so cute, and I know children will love it. For now there are only 3 emotions but I could add more. For now, 2 boards are needed : one to control MiniCat and one to control the eyes. The 2 boards are connected to the same batteries and IR sensor. It took me a while to make it work because I wanted to fit the 2 codes in the same board but unfortunately the library for OLED screens is too heavy (even after reducing it). Feel free to check the code on my Github if you want : For now the code is mainly commented in french for my young students, but if you want English comments don't hesitate to ask me 😊

Hi everyone, I'm desperately trying to control my Nybble using the ardSerial.py executable, in order to try other python scripts and try to add computer vision. I've configurated my Raspberry Pi 3b+ as explained in the assembly instructions : https://docs.petoi.com/chapter4#4-4-raspberry-pi-serial-port-as-interface The 2 boards are communicating but the sketch doesn't start because the MPU can't initialize : It looks like an i2c communication error but I've checked the i2c devices connected on the raspi it correctly detects the MPU .. I don't know why I have this error... I must have missed something but I really don't understand what, could anyone help me please ? Many thanks and best wishes, Lilie

Hello everyone ! I’m a french intern working for a french company QI informatique. I have to design an online robotics course for teenagers based on the amazing robots Nybble and MiniCat. As a result, I will develop new functionalities for the robots and share them to respect the Opensource spirit of the OpenCat project. Today, I wanted to show you the first course based on Nybble : making Nybble a little bit angry when an obstacle prevents him from walking. You can see the result in the video : Of course, it is way more simple than the projects showed in this forum but it can be a good challenge for beginners ! Here is the modified code for the curious ones : https://github.com/LilieBoizu/OpenCatDEV/tree/master/Nybble_Obstacle_detection I keep developing new functionalities. Best wishes to everyone, Lilie
