Does the load average of a computer has effect on a robot's response?
Our lab. has two robots and two computers.
I am running the same code for the human following using deep learning with OpenCV, turtlebot is very very nice but Rabbot is very very slow.
I don't know what is the reason.
The first computer with a turtlebot (Ubuntu 14.04, desktop), this is its load average :
$ top
the output:
top - 21:33:31 up 1:12, 4 users, load average: 0.06, 0.03, 0.05
