SLIDE 3

Robotic Sentry gun
Protects your property
Fully autonomous
Shoots with foam darts
Friendly user interface
Fully customizable

SLIDE 4

Loyal to the Key

Tilt Mechanism

Simple Operation Swivel Mechanism

SLIDE 5

Usefulness

Eliminates need for night shift guards
Compact, can be placed anywhere
Angle of scan can be adjusted for maximum

flexibility

SLIDE 13

Operation: Setup Mode

Currently implemented options include

– Angle of horizontal scan/activity – Maximum number of shots fired per target – Cool down period interval

SLIDE 14

Operation: Scanning Algorithm

Scans area and saves map
Saved map includes:

– Distance to objects – Uncertainty of readings

Saves image of area without motion

SLIDE 15

Operation: Attack Mode

Constantly monitors area for movement
Performs quick scan to see what moved
Shoots target
Waits for a cool down period
Returns to monitoring area for movement

SLIDE 16

Operation: Sanitizing of Readings

Multiple readings are recorded per location
Custom hysteresis set for each reading
Movement is ignored if within threshold
