The Micro-CART project teaches students how to familiarize themselves with a project that they were not part of from conception to completion. Students must quickly become familiar with Micro-CART at its current state and determine how they can actively contribute to the team. This experience is useful as many engineers may not experience projects in the workplace that they design, implement, test, and maintain.

AbstractThe Association for Unmanned Vehicle Systems International (AUVSI) holds an International Aerial Robotics Competition (IARC) every July at Ft. Benning, Georgia. Collegiate teams from around the world enter unmanned aerial vehicles (UAVs) capable of autonomous flight into this competition where specific mission objectives must be met. The goal of the Microprocessor-Controlled Aerial Robotics Team (Micro-CART) is to enter a UAV into the entry level of IARC by developing a fully-autonomous helicopter. A secondary vehicle is also being developed for later stages in the competition. This will showcase the role of Iowa State in the field of unmanned aerial robotics and provide valuable design experience to Micro-CART team members.
• Continued support from Iowa State University and Lockheed Martin
• Sensor System Will Provide All Necessary Flight Software Inputs
• Current helicopter airframe limitations (lift, weight, speed, fuel)
• Power considerations for on-board hardware
• Robust autonomous flight system modifiable for various missions
• Documentation covering all aspects of research and accomplished tasks
• Design and build a primary and secondary aerial vehicle capable of autonomous flight
• Develop an integrated system of sensors to control the aerial vehicles
• Enter entry level IARC, summer 2007
• Outside in fair weather conditions• Maneuver within a 430-acre area• Varied topography and a few man-
made obstacles
• Micro-CART team members will use the vehicle to compete in the IARC
• Future uses in aerial surveillance, law enforcement reconnaissance

Funding Provided By
Design Objectives• Develop an aerial vehicle to compete in entry level IARC• Develop a secondary vehicle for higher level IARC
Functional Requirements• Hover via autonomous flight-control• Self-navigation to global positioning
system (GPS) waypoints• Communication between both vehicles
Design Constraints• Size and weight considerations• Cost minimization• Low power consumption
Measurable Milestones• Autonomous flight-control software testing• Sensor implementation and testing• Communications and ground station development• Test flight(s): hover, translational test flights
Proposed Approach• X-Cell #1005-1 gas helicopter as primary vehicle• Quad-ducted fan platform as secondary vehicle• On-board controller (PC/104) will provide sensor interfaces and
processing resources for flight control software• GPS unit and magnetic compass will provide data for navigation• Inertial measurement unit (IMU) will provide helicopter dynamics• Sonar arrays will provide data for object detection and avoidance
Technologies Considered• Software controlled basic stability• Self-navigation to GPS waypoints
Testing Considerations• Individual hardware unit testing (GPS, IMU, Sonar)• Integrated hardware unit test with flight-control• Hover and translational flight tests• Tethered flight testing with test stand
