Nano-size Quadrotor
Our first cyberphysical platform is the nano-size Bitcraze CrazyFlie 2.0 [1]. It has been used in many projects due to its dimension, versatility and its open-source and open-hardware nature. Nowadays is well known how UAVs with high level autonomous navigation capabilities are a hot topic both in industry and academia due to their numerous applications. However, autonomous navigation algorithms are demanding from the computational standpoint, and it is very challenging to run them on-board of nano-scale UAVs (i.e., few centimeters of diameter) because of the limited capabilities of their MCU-based controllers. The nano-quadrotor is an appealing platform (among others) for solving this challenging task. Moreover, recent evolution of our research effort PULP
Nano-size Blimp
One of our favorite nano-size platform is the IIS/TIK Nano-Blimp. A nano-sized blimp is a perfect candidate for long flight times because helium, a lighter-than-air gas, can provide lift and significantly reduce the energy requirements for flight.
In the first project of this series we introduced the nano-blimp. We demonstrated that, thanks to the helium-filled balloon, the energy requirement for hovering is significantly reduced. Then, we extended the functionality of our first self-sustainable blimp prototype introducing additional motors and on-board camera, paving the way for autonomous navigation. We enabled first horizontal movement creating a blimp that is able to move in three dimensions. Then, we expanded the on-board processing capabilities with visual sensors and we incorporated, optimized, and improved a simple object tracking algorithm for autonomous flying nano-size UAVs.
