Micro aerial vehicle: Micro ultrasonic sensor - Sense and avoid

Introduction

The ability for vehicles to navigate unknown places is critical for autonomous operation. Mapping of a vehicle's environment and self-localization within that environment are especially difficult for an Unmanned Aerial Vehicle (UAV) due to the complexity of UAV attitude and motion dynamics, as well as interference from external influences such as wind. By using a stable vehicle platform and taking advantage of the geometric structure typical of most indoor environments, the complexity of the localization and mapping problem can be reduced.  Interior wall and obstacle location can be measured using low-cost range sensors. Relative vehicle location within the mapped environment can then be determined. By alternating between mapping and localization, a vehicle can explore its environment autonomously. This paper examines available low-cost range sensors for suitability in solving the mapping and localization problem. A control system and navigation algorithm are developed to perform mapping of indoor environments and localization. Flight Simulator and experimental results are provided to determine feasibility of the proposed approach to indoor navigation.

Modular Design

Brain Box Blimps


Blimps provide exceptional long endurance guidance, monitoring, reconnaissance, FPV, UAV, but are limited in the amount of payload they can carry owing to the limited buoyancy of Helium or Hydrogen. The slim, compacted and light BrainBox modules are ideal for such applications and can provide complete control authority, sensing and computing needed for the most complex of R&D tasks or real-world jobs.


The Georgia Tech Systems Research (GTSR) Group has built biologically inspired robotic blimps that were recently presented at the Capstone Design Expo. The project titled "RoboBlimp: A blimp based flying sensor network” was developed by a team of undergraduate students under the supervision of Dr. Fumin Zhang. The students (Edward Aguilar, Phillip Cheng, Joshua Holley, Kevin Lemus, Weston Smallwood, and William Zhang) produced several working prototypes of computer controlled aerial shot indoor blimp platforms that will be used by the GTSR lab in research on environmental sensing, swarm control, and bio-inspired robotics. These indoor helium blimps are neutrally buoyant floating robotic platforms that offer long flight and loiter times, and safe, stable, low noise operation. The blimps' hardware and software systems were bio inspired design to be adaptable to support research on environmental sensing and human robot interaction. Robotic blimps are useful for providing communication support, eyes in the sky, and transportation services for a broad scope of real world applications.

Golden Quotes from Dr. Fumin Zhang

“Mobility poses great challenges to the Internet of Things when networked mobile agents are concerned. Distributed sensing and control will need to be coordinated through information exchange over flexible ad-hoc wireless networks to guarantee sustainable, reliable and affordable data streams flowing across the network. Insights into the coordination and decision making mechanisms used by animal groups serve as open source of inspiration for my research to solve these problems.”
