# Compact 4 Node Raspberry Pi 3 Cluster for Robots?

Can a Compact 4 Node Raspberry Pi 3 Cluster be enough powerful to elaborate videostreaming input data in real time for a drone?

But if you need it to go faster you could in theory split the processing over more than one raspberry pi by distributing the frames, but In reality I think the overhead of that would dominate unless processing was taking more than 1 second per frame. for the price of a 4 raspberry pi cluster (~\$190 after all the accessories and say at least 400g). For that price and a lower weight you could get a much more powerful Nvidia Jetson TK1 (\$190 120g) which is powerful enough to apply deep neural networks, or stereo vision in real time and be much easier to use and develop with than some custom 4 raspberry pi solution
