Great work! I've always been fascinated by self-driving cars. Can you share more about the sensors and software you used?
autonomous123 5 months ago next
I used a combination of cameras, LiDAR, and radar to detect the environment. For software, I wrote a custom stack using ROS and TensorFlow.

What hardware did you choose and why?
ai_explorer 5 months ago next
Interesting. Have you considered the Jetson Xavier NX or Jetson TX2?

Impressive! How did you handle data fusion from all those sensors?
autonomous123 5 months ago prev next
I picked an NVIDIA Jetson AGX Xavier for its powerful GPU and the rich set of interfaces to connect sensors. It's also power-efficient and compact.

I have, but I needed the extra oomph provided by the AGX Xavier to process sensor data in real-time. The other options just didn't quite meet my requirements.

Would it be possible to use open-source software stacks in a project like this?
autonomous123 5 months ago next
Absolutely! I used open-source programs like ROS, TensorFlow, and Autoware for my project. I think utilizing the open-source ecosystem in a project like this is vital for innovation and progress.

Any plans for open-sourcing your own codebase or releasing a DIY kit for makers interested in self-driving vehicles?
autonomous123 5 months ago next
That's an excellent suggestion, and I've been considering it. I'll need to clean up the code and create concise instructions before making it available. Stay tuned!

What's the range and power consumption like on your vehicle?
autonomous123 5 months ago next
The car's current range is around 150 miles per charge, and typical power consumption depends on various factors like speed and driving habits, but it's energy efficient overall.

What learning algorithms and network architecture choices did you make for decision-making?
autonomous123 5 months ago next
I employed an Actor-Critic method, learning how to navigate road networks. For network architecture, I used a DQN with dilated convolutions to process image and sensor data.

How did you ensure the robustness and safety of your software through real-world testing?
autonomous123 5 months ago next
By driving the vehicle tens of thousands of miles under various conditions and collecting data for anomaly detection and correction. I also employed monitoring systems and fail safes to prevent catastrophic failures.

Mind sharing the cost of building such a vehicle? I'd love to know the ballpark figure even without an itemized breakdown.
autonomous123 5 months ago next
Building this vehicle cost around $50,000, including hardware, sensors, and labor. The cost scales up depending on the desired specifications and requirements.
