1 Basic Drone: Bits and Pieces Core Components: Plane Kit Motor + ESC + Batteries Autopilot + GPS + Compass Rx Receiver + Servos Optional Components: Mapping Camera + Trigger Telemetry Tx FPV Tx + Camera

2 Basic Electronics

3 Android Ground Station $3 OTG Cable + $50 Receiver

4 Fixed Wing Planes “Skyhunter” 1.8m, 2.5 kg Payload $140

5 Portable Field Mapper “X-6” 1.5m, 1+ kg Payload $140

6 Cameras Sony Nex-5r + Sigma Lenses

7 “Brushless” Gimbal Brushless Gimbal Stabilization Revolution

8 Alexmos Control Board

9 Fixed Wing Component Costs Commiditization of components – global sourcing. Example: Foam Planes → China: $50-$200 Autopilot → California: $200 Fixed wing Gimbal → Vermont: $150 Motors, ESCs, etc → Hongkong: $300 Entry level FPV → California: $250 Drone Cost: ~$500 - $1,300

10 Multirotor Drones

11 High Quality Heavy-Lift Hexacopter Heavy lift Hexacoper Frame Kit: $325 6 motors and 6 ESCs: $400-700 Autopilot: $200 Telemetry: $100 2 Axis Brushless Gimbal: $250 Mini 2-axis Alexmos: $150 Cost ~$1,500-$2,000

12 Performance Fixed Wing (2m) Endurance: ~1+ hr. Speed: cruise 40-70 kph (100+kph max). Payload: Gimbal + Camera < 800g. Multirotor (800mm) Endurance: 15-20 min. Speed: <50 kph. Payload: ~3 kg (dslr + 3 axis gimbal).

13 Pros / Cons Multicopter PROS Good in rugged terrain, where a fixed-wing would be difficult to operate. Landing a fixed-wing = DAMAGE. Auto-takeoff and landings. Very stable in hover. Optimal for small site mapping. CONS Short flight times. More expensive than fixed-wing. More complicated. Parts failure can be catastrophic.

14 Fragile

15 My Project - Maps The use of Drones for High Accuracy Photogrammetric Mapping: Orthorecified images DEMs (Digital Elevation Models) 3d Models Fixed Wing: Small area mapping Typical 1-10 km2 (5-30cm GSD). Multirotor: Site specific Ideas to Explore: Brushless Gimbal Systems (Alexmos) – worth the trouble? Optimal Camera + Fixed Lens
