Yesterday, with Ros, Iperf, Nettest tested the bandwidth and CPU occupancy of the CMM02NODE06-->CMM02NODE01, sending a packet length of 2KB, the test results are:Bandwidth send-side CPU utilization at the receiving end CPU usageROS 4.42gb/s, 80% 100%Iperf 4.66gb/s, 100% 70%Nettest 4.38gb/s, 100% 71%found that both Iperf and nettest are send-side CPU reached 100%, and the receiving end only accounted for the 70%;ro

This paper mainly introduces the configuration and use of navigation function package set.
1 Robot Setup
Assuming that we have set up the robot in a specific way, the navigation feature pack set will make it available for movement. This configuration is outlined in the figure above. The white part is the required and implemented component, the gray part is optional and implemented , and the blue part is the component that must be created for each robot platform.

It is believed that many enthusiasts stop at expensive robot prices. Although with Arduino, but a very weak capacity of the robot car cost also one hundred or two hundred yuan. It is more time-consuming and laborious to build your own robot.
