Mechanical SystemChassisTransport

Energy Collection Due to the need for portability, an outside

energy source is needed. Solar Panels are main focus of collection subsystem.

Based on amount of energy delivered to the vehicle and the time required to recover energy from sun about 14 watts is needed.

Energy Storage Due to varying charging periods a storage

system must be implemented. With 1 hour flight time/charge time a 9 hour

mission would require 240 watt-hours. Thus, a battery will be used to store energy

within the ALP.

Control System In order to communicate with craft in flight, a

GPS system must be used to locate the helicopter from the pad. A small camera on the craft locates GPS and flies to location.

Switches to close range landing device once close enough to the landing pad.

In order to communicate with the craft, a controller is needed.

Control System Cont’d Many controller forms are being considered

from microcontrollers to single-board computers.

Chassis Ultimately, the chassis will house all electrical

components and provide a landing surface for the craft.

Different materials were researched on the basis of cost and how well it would hold up under different weather conditions. ABS plastic seems to be best choice.

Solar panels will be mounted on top of the chassis using drawer slides allowing the pad to be more compact for transport.

Transport Tree-Stand back pack straps proved to be able

to carry heavier weights while still giving comfort to the transporter.

Should be able to be either detached or moved off to the side to give the ALP a more level landing surface.

OVERVIEWThe 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.

In order to finish on time we will follow the tentative timeline as closely as possible which accounts for unexpected delays and allows plenty of time for testing and troubleshooting.
