  2. Team Members Cory Fulkerson (Project Manager) - Mechanical Engineer John Graham - Computer Engineer Clayton Hooks - Electrical Engineer O’RaphaelOkoro - Electrical Engineer Tyler Wilson - Mechanical Engineer

  3. ICARUS Overview Integrated Complex Advanced Robotic Unmanned System Autonomous Flying Helicopter Co-axial, tilt-capable, quad-rotor vehicle More maneuverable and efficient vehicle than comparable quad rotor helicopters

  4. Reason for ALP The ICARUS Automatic Landing Pad (ALP) will provide a secondary recharge opportunity for the ICARUS vehicle when out in the field during missions which will extend the range of the vehicle as well as increase mission duration.

  5. ALP Requirements Must be robust and lightweight to be field transportable as well as waterproof to protect the electrical components within. Must Effectively communicate with the vehicle to guide it to the pad and be fully autonomous. Must have onboard energy storage and be capable of recharging the vehicle after it has landed in a timely manner. Must recharge itself through solar panels in order to repeat the process.
