Animals such rats and birds might see your vegetables as free food. Or your neighbourhood’s cat might have taken a liking to your lawn as its personal toilet.
One solution to deter these “unwanted guest” is by shooting at them with a water gel pellet. The garden defender has a webcam that continuously scans your garden. When an “unwanted guest is detected”, the garden defender with aim and shoots.
Detect unwanted guests: OpenCV and a deep learning algorithm “YOLO” were used for object detection.
Aim and shoot: When an unwanted guest is detected, will aim and shoot
Garden surveillance - large field of view: Robot will continuously move the webcam left and right to maximize the field of view when an unwanted guest not detected.
- 3D printer
- Soldering Iron
- Glue for plastic parts
- Phillips screwdrivers
- Hex key set (Millimetric)
Build and assembly
1.- 3D print STL file
2.- Using the soldering iron insert the threaded inserts into the plastic parts. They must be flush.
3.- Build blaster: Insert Neopixel led rings with their cables on blaster cases, and route the cables.
4.- Add the servos cable and route it inside the blaster case
5.- Place the camera and blaster inside de blaster case. Double check that the cables are routed correctly.
6.- Align the camera cable and close the blaster case. Optionally, you can add cord protector wire loom.
7.- Add x7 M3 screws using a hex key M2.5.
8.- Paint plastic parts. Optionally, first, use a primer.
9.- Add x4 feet into the main base and secure them with x4 M5 screws using a Hex key M4.
10.- Add the switch into the main base and secure it with x2 M2 screws using a Phillips screwdriver.
11.- Add the servos driver into the main base and secure it with x2 M2 screws using a Phillips screwdriver.
12.- Add the relay modules into the main base and secure it with x2 M2 screws using...Read more »
