Camera Mount Design |
The final camera mount design, while resembling the original concept has been optimized to decrease the size of the mount as well as omit the need for beveled gears. The new design incorporates direct drive servos to achieve a more efficient design. The new design will utilize two 1.17 Nm servos to control the pan and tilt of the sensor and the frame will be constructed of inexpensive square tubing. The base, consisting of the panning servo and its housing, will be bolted to the platform while the tilting mechanism, consisting of the tilting servo and the sensor cradle, will rotate above the base. |

Platform Design |
|
The final platform design consists of the mounting plate and the protective dome. The mounting plate itself measures 40 inches in diameter and is 3/8 of an inch thick. It will have tapped holes for all of the sensors, located at the plates center, as well as the camera mounts. The slotted design was not utilized in the final design because of its structural weaknesses and also because of the difficulties associated with sealing the system for weather protection. Instead, the group decided to allow for a total of eight cameras to be mounted simultaneously, thus removing the need for extra mounting locations. The 17 inch tall 0.2 inch thick dome will be molded out of clear acrylic and will serve as the protection from the outside environment, and will be mounted on the plate with a series of screws around the plate’s perimeter. All components of the final design were subject to rigorous analysis and calculations to ensure that the system will satisfy all of the designated specifications. |
