@Max....a practical and achievable DIY strategy might be to aim between the two. Use the leaf blower (or two or even 4 of them) and use a controller to control them (and/or control surfaces or vents) such that you can command motion in any direction like the big one, or maybe have an additional leaf blower or a fan for propulsion like a swamp buggy.
Just make sure not to fill it with eels........ :-)
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.
