Hi,

Just tried to see if hector slam algorithm works on raspberry pi3 with ubuntu MATE 16.04 w/ ROS kinetic. Unfortunately seems that the computational power of the board is not enough to handle the data stream while map is created so our discover is that raspberry is not enough powerful (we tried the commands on another pc and the map is created successfully).

So now our question is: Is it possible to stream the data coming from laser scanner (connected to Pi3) to another powerful pc. Do proper elaborations and then send final commands to the raspy again (cmd_vel..). If yes which connection should we use? And how to do that? Any hints?

Thanks

Short answer is yes. The pi has plenty enough power - I would ensure you have a high bandwidth WiFi channel - I use a 300Mps adapter on a Raspberry Pi 2 for the set up you mention - works fine. 150Mps is a bit slow.

Additionally: make sure to compile things with optimisations enabled. With CMake / catkin: -DCMAKE_BUILT_TYPE=Release (or RelWithDebInfo).

How can stream data from raspy and then analyze it in the other PC?

Simply install ROS on the other PC and run a Hector SLAM node there listening to the topics it required.
