Jacob Hernandez / ros_lib_kinetic

This is a fork from the original, including a small change in the buffer size of the hardware interface (increased to 2048) and decreasing the number of publishers and subscribers to 5. Besides, the library about the message Adc.h was modified so as to increase the number of available Adc channels to be read ( from 6 to 7 ) For this modification, a change in checksum was required

Dependencies:   BufferedSerial
