Bipedal Robot RL Simulation on Jetson Orin Nano
Training a two-legged robot to walk using PPO and the Genesis physics simulator, running entirely on the Jetson Orin Nano.
PyTorch Setup on Jetson Orin Nano
The Jetson Orin Nano uses an ARM64 integrated GPU (nvgpu) with a custom L4T CUDA stack, so standard PyPI torch wheels won't work. This post walks through getting PyTorch running with proper GPU support.
What is initrd?
If you have ever peeked at /boot/extlinux/extlinux.conf, you probably noticed a line called INITRD. Have you ever wondered what this thing is, what it does, and why we need it?
Enable PREEMPT_RT
This guide covers how to enable PREEMPT_RT on the Jetson Orin Nano, transforming it into a real-time operating system (RTOS) ready for low-latency robotics applications.
Get Ready!
To start the Jetson Orin Nano journey, the first step is to figure out where to grab the source code and which build tools are needed.
