Based on personal experience dealing with cockroaches when I lived in a rental apartment in Dallas after college, I can't think of a better insect to send out in droves. I've read about similar work being done by researchers at Texas A&M, where they described the cost of the insects and the electronics as "minimal." with the actual mounting of the electronics being the most costly as it's done by hand. Would be interesting to see how that works!
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.
