Hi, I am trying to run the OpenCat software on a pure Arduino Nano, but I don't even get the software compiled in the IDE before uploading. I get a whole page of errors concerning the MPU6050.h and MPU6050.cpp files saying that the code does not comply with c++ rules and so on. can anybody point me in the right direction here? thanks.
sorry if this is the wrong forum thread .

I thought I'd share a project I've recently done with Bittle in case anyone is interested in exploring simulation with Bittle in a non reinforcement learning application, although one could also use Mujoco for reinforcement learning also.
I used the URDF created for Bittle here. AIWintermuteAI made the URDF files for Bittle a while back, which was a great starting point to get a model of Bittle into the Mujoco simulator made by google deepmind.
My project aimed to use model predictive control (MPC) to generate optimal gait patterns to run open loop on the Bittle robot. The first step was to get a model into the simulator. To do this, I converted the URDF model to XML format for the simulator. Then I created the environment and configuration to use Mujoco Model Predictive Control (MJPC) with Bittle. MJPC was also developed by google deepmind.
MJPC effectively performs forward rollout…
Yes, it's the exact model of our production model. The previous one was reverse engineered by our users.

I am completely new to Bittle, just finished assembling one for my grandson. Currently at calibration stage, downloaded and installed Desktop app on my Macbook running the latest OS. App launches, but it is slow and halting, and frequently does not respond to any clicks on the firmware or calibrate options. I did grant it permission and sometimes one or two of the servos move and the board makes a sound, but I cannot get the program to run smoothly. Any ideas?
Please try to run the desktop app in the terminal via the following command: /Applications/Petoi\ Desktop\ App.app/Contents/MacOS/Petoi\ Desktop\ App
Then please attach the log in the terminal interface.

Hello, I have a bittle x robot. I removed the old board (BiBoard) and installed the Nyboard and connected it to the servos and made sure of the connection. I downloaded the code and made sure to activate the type of board and the robot, but when I started it and gave it some commands with the remote, the servos did not work well. I calibrated the servos, some of them work and some do not, so I installed the old board to return it to work, but the servo became worse. acutally the servos when I bought the robot after a few months Sometimes it didn't work well. Is there a solution to the problem because it happened suddenly? Is the only solution to reassemble the robot from scratch or buy a new servos or are there other solutions?

Hi everyone, I have been doing some work on the project. I have removed the old board (BiBoard) and installed the new board (Nyboard) and the music and lights worked on the new board I expect that it is working now and I only have to upload the code, and as for the Raspberry I downloaded the system on it and I installed the Raspberry over the Nyboard using female headers and it worked and also I entered the Raspberry system using Windows Powershell but now I have a problem I want to install the camera and voice and AI chip on the Raspberry we can do it using the Raspberry GPIO But you know how the ports of these chips cannot be mounted on the Raspberry pins. If Anyone have advice, I would be grateful to you.
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.

@rhongzongli - I modified the bittle back with a dremel so it fits on the bot when I do not have the Pi attached. It would be nice to get a back that already has a nice cutout for the connector when ordering a presoldered connector or when someone knows they will be adding one. Maybe if every back printed with outline of a "knock-out" printed on the inside, it would allow those with the connector to precisely cut out the hold with a utility knife?
well I get the same messages as dr. Rongzhong showed above. but I understand that this are warnings that can be ignored. in the mean time, I have uploaded the code to an Arduino UNO succesfully. Although the PCA9865 calibration with PWM 8 to A3 (or PWM3 to A3) does not finish.
when I do install the main_skecth, I do get messages on the serial port and can send commands. But unfortunately, the servos seem to be not working correctly. with the ksit command, my cat tries to strangle himself by turning the neck 360 degrees and the rear left thighis going all the way back. some kind of yoga I suppose...
