Payload Design

TRIPOD
The objective of the TRIPOD is to detect and differentiate between three randomly placed ground targets located within a 300 foot radius of the launch pad. Upon identifying and differentiating between the three targets, the TRIPOD will land, upright itself, and provide proof of mission success. The TRIPOD will fulfill these objectives while protecting all on-board electronic and mechanical components. The TRIPOD will additionally remain reusable, ensuring all payload components are undamaged for successive launches.


The payload includes actuated landing petals and immobile panels that protect the electronic components throughout the mission. Landing petals will be released using a servomotor, mounted to the top of the TRIPOD. Once released, torsion springs will rotate the petals into an opened position and orient the payload vertically.
WIDE ANGLE CAMERA
The primary design for the imaging system is a Raspberry Pi Rev 2 camera. The camera will sit inside of a 3D printed housing made from HIPS. The housing component will be located on the bottom of the TRIPODs chassis and the cameras will be oriented downward. The wide angle camera will ensure that the targets are in its field of view for as long as possible during the descent.
FLIGHT COMPUTER
The Flight Computer will perform all the functions necessary to complete the mission objectives. These include target detection, control, and payload location monitoring. It will consist of a Raspberry Pi with a number of functional components that include a GPS, IMU, radio transceiver, camera, and a servo/brushless motor controller. Batteries will be used to power both the Raspberry Pi and the motor controllers.


The Flight Computer will initiate the imaging phase upon detection of light. This will begin the target detection portion of the mission. When the payload is approaching the ground and its main parachute has been deployed, the Flight Computer will trigger the landing detection phase. The mission will complete with the extension of the TRIPOD's legs.
