If you are interested in FIRST robotics, here is a story on EDN that talks about this year's FRC competition, where competitors have to complete their robot in a short time window. And, here's another story (shameless plug) that profiles the team my daughter competes with in FIRST Robotics FTC competition.
NI has also been involved with LEGO competitions, to the point where students use LabVIEW-based software to control robots. I recall an exhibit severalyears ago at the Boston Museum of Science on Lego Mindstorms.
Having witnessed the F.I.R.S.T. competions first-hand (sorry!), and as a mentor to Team 293 SPIKE, I would hands-down go with National Instruments. Their contributions to the electronic control and interface features on the robot challenges let high school students (and even some 8th-graders) gain the satisfaction, experience, and fun of creating a robot that they can control and be proud of.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
