Teaching Robotics with ROS on Ubuntu at SRU
This week, as part of my work on the Ubuntu Robotics team, I headed up to Slippery Rock University in northwestern PA to meet with Dr. Sam Thangiah and to introduce students to the Robot Operating System (ROS). New semester, lots of new opportunities for learning!
We started with a really simple robot environment. Check out this build! This Raspberry Pi runs an Ubuntu 18.04 image which gives it all the built-in LTS security advantages. It’s mounted on piece of plexiglass with two motors and a motor controller board from the PiHut. We worked through about 75 lines of sample python code which hooked the RPi.GPIO library to control the general purpose I/O pins, and we created an abstract Motor class. This got our two-wheeled robot up and running…running right off the table. Oops.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
