Problem Specification
Description:• A minimally invasive
reconnaissance robot that will be able to autonomously navigate and search a course for victims.
Features:• EMF detection and IR sensors to
locate victims and a hazard• LCD screen and speaker to notify
user of victim locations and conditions
Course Description
Specifications:• 2.4 m x 2.4 m floorplan• Four 1 m2 rooms
Obstacles:• Two Variations
4 cm x 9cm
2 cm x 2 cm
Victims and the Hazard
Victim Specifications:• 8.9 cm diameter, 4.1 cm high• Emits a 33-kHz sinusoidal wave signal• Uses an LED to differentiate between: Dead, Alive,
or Unconscious• Up to three victims per room
Hazard Specifications:• 40 cm x 40 cm core• Emits a 44-kHz sinusoidal wave signal• Mounted underneath the floor of the course in
one of the four rooms
Technical Constraints
Name Description
SizeThe robot must not be larger than 20 cm x 20 cm x 20 cm
SensingThe robot must detect electromagnetic fields at 33kHz and 44kHz resonant frequencies. The robot must also detect a green LED.
ManeuverabilityThe robot must be able to maneuver over or around objects.
SpeedThe robot must be able to reach a speed of at least 20 cm/s
MappingThe robot must be able to map objects within the course.
Practical Constraints
Type Name Description
Sustainability Dependability The robot must require minimum maintenance
Manufacturability ModularizationSubsystems must be able to be detached and tested separately
