MODULE DETAILS

Module 15: Machine Communication Technologies

 

Nominal duration: 4 weeks (32 hours total time commitment)

 

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

 

 

MODULE PURPOSE

 

 

Data communications in all its facets, be that analog or digital, wired or wireless, underpins the operation of the entire modern production plant, and hence most industrial Mechatronics applications. However, even with educational robotics there is a need to download software from a PC or laptop to the robot. Wireless technologies are used to communicate with mobile robots, whereas industrial robots employed in the manufacturing Industry typically communicate via a field bus. This unit will cover both wired and wireless technologies, ranging from the ‘old’ RS-232 standard to the latest Ethernet-based technologies.
