please teach me about ‘[https://github.com/NVIDIA-AI-IOT/jetbot/wiki/examples](https://github.com/NVIDIA-AI-IOT/jetbot/wiki/examples)’ ([https://www.sparkfun.com/products/18486#documents-tab](https://www.sparkfun.com/products/18486#documents-tab)) I want to use camera function. Jetson reboots when camera function is used. For example, When I try to run the code given below, jetson restarts… * * * directory:Notebooks/collision\_avoidance/data\_collection.ipynb import traitlets import ipywidgets.widgets as widgets from IPython.display import display from jetbot import Camera, bgr8\_to\_jpeg camera = Camera.instance(width=224, height=224) image = widgets.Image(format=‘jpeg’, width=224, height=224) # this width and height doesn’t necessarily have to match the camera camera\_link = traitlets.dlink((camera, ‘value’), (image, ‘value’), transform=bgr8\_to\_jpeg) display(image) * * * why? ---

thank you for your reply. I ran the below command. ーーーーー git clone [https://github.com/NVIDIA-AI-IOT/jetbot](https://github.com/NVIDIA-AI-IOT/jetbot) cd jetbot sudo python3 setup.py install sudo apt-get install rsync rsync jetbot/notebooks ~/Notebooks sudo nvpmodel -m1 sudo nvpmodel -q ーーーーーー the motor can move.(notebook1,Example 1 - Basic Motion) It is confirmed that the camera also projects in a different way ---

For the latest instructions, follow this guide: [https://jetbot.org/master/](https://jetbot.org/master/) You’ll have to install the [[SparkFun Qwiic Python package](https://github.com/sparkfun/Qwiic_Py#pypi-installation), but the code changes for our hardware should have been [[pulled into the Nvidia’s jetbot repo](https://github.com/NVIDIA-AI-IOT/jetbot/pull/467). Additionally, I would recommend using [[iPython](https://ipython.readthedocs.io/en/stable/index.html#) to exceute lines individually instead of the enitre cell of the Jupyter notebook. Jupyter notebook doesn’t always show all the error messages and executing each line individually will help you isolate where the error is occuring (i.e. which instruction is cauing it).]([IPython Documentation — IPython 8.26.0 documentation](https://ipython.readthedocs.io/en/stable/index.html#))]([Add SparkFun hardware support by santaimpersonator · Pull Request #467 · NVIDIA-AI-IOT/jetbot · GitHub](https://github.com/NVIDIA-AI-IOT/jetbot/pull/467))]([GitHub - sparkfun/Qwiic\_Py: Python package for the qwiic system.](https://github.com/sparkfun/Qwiic_Py#pypi-installation)) ---

Thank you🙇‍♂️ Is it possible to implement collision avoidance and automatic driving on a container? I am investigating this, I was able to confirm by referring to the manual that collision avoidance and automatic driving are possible on the host OS. ---

Again, I wouldn’t follow the instructions from the GitHub wiki. They are older instructions for an older version of the software. I would focus on the information from the **[jetbot.org](http://jetbot.org)** website. They have some information here regarding that question: [https://jetbot.org/master/examples/comm … mples.html](https://jetbot.org/master/examples/community_examples.html) Also the information there, indicates that the “jetbot” software is already running in a docker container: [https://jetbot.org/master/software\_setup/docker.html](https://jetbot.org/master/software_setup/docker.html) Also, most of our expertise will be limited to assemblying our kit and getting started with their examples. I would recommend the [[Nvidia forum](https://forums.developer.nvidia.com/c/agx-autonomous-machines/jetson-embedded-systems/jetson-nano/76) for more technical questions.]([Jetson Nano - NVIDIA Developer Forums](https://forums.developer.nvidia.com/c/agx-autonomous-machines/jetson-embedded-systems/jetson-nano/76)) ---
