1. DRONES & POWER LINES FALL OF 2015 RESEARCH 2 GRACE // CHARLES // JASKIRAT

3. CONCEPT STATEMENT The problem: Inaccessible areas need to be inspected by power line workers before construction such as, large dense forests and mountain terrain. The power line workers are at risk when inspecting inaccessible areas to establish new power lines. Solution: Can drones be used with photogrammetry to help inspect terrains and dense forests prior the construction of power lines?

4. Drones & photogrammetry to map out terrains prior construction of civil infrastructures. PURPOSE OF USING DRONES

5. WHO IS OUR USER? POWER Grid Workers- people who need to inspect city bridges for maintenance and safety. We hope to provide them an alternative method of inspecting terrains for wire line construction.

7. PRECEDENCE RESEARCH

8. Analysis of photographic data will also be used to check pylons, says Salisbury. Instead of inspecting steelwork on a pylon, we can now can fly a helicopter or drone to take high-definition pictures remotely, which we can use to monitor the pylon's condition over time." CASE STUDY RESEARCH

10. OUTCOMES/ DELIVERABLES 1.We will shoot a video and create a scenario on how drones and photogrammetry can be used to inspect terrain for power line construction. 2.We plan to deliver this video and narrative to Power Grid India and National Grid USA as a proposal to use drones. DRONES USER (POWER LINE WORKERS) PHOTOGRAMMETRY

11. Quadcopter Size: about 55 x 55 x 5cm (21.6 x 21.6 x 2 inches) Weight: 3.2 pounds Gyro: 6 axis Flight Duration: 8-10 Minutes Remote Control Distance: 100-150 Meters Recharging Time: 1-1.5 Hours Battery For Quadcopter: 7.4V 850 mAh Battery For Transmitter: 6 x AA Battery (not included)

12. TEST 1- FINDING THE TYPE OF DRONE NEEDED Testing the Cyclone

13. TEST 2- DRONE WITH A GO-PRO Testing the Cyclone when attached to a go-pro for possibly using photogrammetry.

14. INSIGHTS FROM FLIGHT TEST WITH GO-PRO The Cyclone drone was too weak to hold the go-pro. The battery drained really fast Drone is not steady (flight) straight and evenly leveled above the ground Difficult to keep it circling around an object like a chair The size of the space was perhaps too small; need more flying space to circle around an object. * Tried flying it in circles and straight AN ACTUAL DRONE USING A CAMERA WOULD NEED THE FOLLOWING TRAITS: Drone must be strong enough to carry a professional DSLR The longer battery life really fast Not ideal to extract photo age from video using go-pro (avoid blurring of images while in motion) Camera SHOULD be able to take multiple quick shots AN IDEAL CAMERA:

15. FOR NEXT WEEK’S VIDEO SHOOTING Create a video scenario and pitch it to Power Grid India. We’ve created our narrative story for shooting.
