Does it have to be ARM based? Most old laptop (you probably already own) can do everything a Pi can, but better at negligible energy cost. If you want to stream, you can remote control an old android for instance. If you want something similar with good graphics, Jetson Nano is good.
- hutzlibu 5y agoWell, size and battery life is important, when you want to use it as the heart of a robot for example. And yes, a android device (with broken and deactivated screen) is maybe the way to go for small size mobile computing power.
- GhettoComputers 5y agoWhat does "heart of a robot" mean? If it just needs to be remote controlled you can do that with simpler hardware like arduino. Do you need computer vision? Jetson has good support for that. Do you want it to be for edge computing? It just has to relay info to a server. What is your project? The Jetson is probably the best choice. Saying GPU is very vague, there are GPUs that are good at decoding video for instance that might not be useful.
- hutzlibu 5y agoNo concrete project as of now, but different ideas around semi-autonomous robots. And since they require heavy computation sometimes, I would like to offload that to the gpu if possible. Jetson sounds interesting. But mobile phones offer many sensors, computing power and a battery all packed together, so I might start with that. Or rather, have a smartphone for computation and remote connection and a arduino for directly controlling the servos. Or a lego mindstorm. Or both.
- GhettoComputers 5y agoYou’ll want a breakout board to connect it to motors, or see other projects. It’s possible to make a separate mobile platform for the sensors on the phone and have it gather info. You’re going to want to look for NPUs and probably not GPUs. If you don’t have any idea check this out for inspiration. https://arxiv.org/abs/2004.10934 https://arxiv.org/abs/2004.10934 The DJI founders wanted engineers to be seen as hero’s instead of sports stars.

- hutzlibu 5y agoWell, I have seen and done some projects already, too. And tons of ideas for new ones, but am currently occupied with something else. What I am doing right now is looking what is out there. So I am quite open about plattforms, but actually I would prefer simplicity. But powerful. Something that has the potential to run WebGPU in a decent way (once that becomes stable).
- GhettoComputers 5y agoYou definitely want the Jetson. Great support, decent hardware, CUDA, Linux, etc. I was called a shill for being sad that ARM and Nvidia didn’t merge but I think this is the best quality device, and has tons of support.
- chaosharmonic 5y agoEh. Sometimes there are legitimate technical wins even for things that are otherwise problematic. The TMo/Sprint merger has had issues, for instance, and I personally have been less favorable to it as time went on, but it didn't mean I wasn't excited at the time to see one more death knell for CDMA. Also Nvidia has been pretty open-source friendly with their ARM platforms in addition to their being pretty powerful in their own right, and that doesn't have to be mutually exclusive with the concerns it would raise if they controlled the whole ecosystem of ARM platforms.
