Micro-Controlled Aerial Robotics Team Abstract In July of every year, Georgia Tech University hosts the International Aerial Robotics Competition (IARC).

Micro-CART intends to launch Iowa State University into this competition. The complexity of the design and implementation of the project is far more involved than two semesters of senior design, therefore this is an ongoing project with an expected initial completion date of Spring 2003 for July 2003 competition.

AbstractIn July of every year, Georgia Tech University hosts the International Aerial Robotics Competition (IARC). The primary task is to send an unmanned autonomous flying machine to perform a specific mission. The machine may be intelligent or preprogrammed, but may not be flown by a remote human operator. Micro-CART intends to launch Iowa State University into this competition. The complexity of the design and implementation of the project is far more involved than two semesters of senior design, therefore this is an ongoing project with an expected initial completion date of Spring 2003 for July 2003 competition.
Introduction
Design RequirementsDesign Objectives • Outfit an aerial vehicle with necessary sensors and a control system
to allow for navigation around unknown objects. • Transmit data to a ground station. • Process necessary information and deliver necessary commands to
complete a predetermined task.Functional Requirements• Autonomous flight of an aerial vehicle.• Transmit data from an onboard micro-computer to and from a ground
station.• Perform specific assigned tasks outlined by competition rules.Measurable Milestones• Develop a strategic plan to outline future tasks.• Implementation of a sensory system that includes the PICs.• Apply a mathematical software algorithm for processing sensor
information to generate control commands.
General Background: An aerial vehicle should fly to a designated area, perform a set of tasks and report relevant information to a ground station.
Technical problem: To research, design and implement the technology, software and hardware necessary to create a fully autonomous aerial vehicle.
Operating environment: The aerial vehicle will need to operate over a variety of outdoor terrains for a finite period of time during the spring and summer months.
Intended user: Iowa State University Micro-CART members who will compete in the IARC.
Assumptions: • No major changes in IARC rules.• Complex computations will be done using a ground-based PC. Limitations: • The payload carrying capacity will limit the vehicle’s design.• Flight time without refueling is dependent on aerodynamics and
payload, both of which are variable.
Testing
As the autonomous aerial vehicle flies over non-surveyed terrain, it captures images of the surrounding landscape and transmits data to the ground station. The control system ensures the aerial vehicle responds to sudden changes in wind direction and wind speed along with any obstacles that may be encountered. The ground station identifies key landmarks using image recognition algorithms. It then issues necessary commands to the aerial vehicle for completing predetermined tasks.
