Yet another innovative UAV design, the HyTAQ robot was developed by the robotics lab at the Illinois Institute of Technology. It combines a quadrotor design with a rolling cage that allows for both terrestrial and aerial locomotion. This combination allows the HyTAQ to use the same actuator set and control system for both methods of locomotion. Additionally, due to its ability to switch between ground and air travel, the HyTAQ is capable of traveling four times greater and almost 6 times longer than an aerial-only system, and can simply fly over any obstacles it encounters on the ground.

Another one of Joerg Sprave’s fantastic custom crossbow creations, the “Stink Master 2000” is designed for the use of, what else, stink bombs. It’s a breach-loaded, pump-action slingshot crossbow that launches projectiles at 90 miles per hour a distance of 80-100 meters.
