The nodelet package is designed to provide a way to run multiple algorithms in the same process with zero copy transport between algorithms
Normal each Node in ROS run in difference process, one Node mean one process.In order to exchange the data between Nodes we have Interprocess Communication.In case the data very large , eg PointCloud, the computer have to spend more time, effort and memory for passing the data between them.That why Nodelet was born for running multiple algorithms in the same process with zero coppy transport.
