good luck for p3 y’all

Rescue Robots

Rescue robots are deigned to help with search and rescue of hmans after a disaster
Can assist efforts of rescue teams by searching and mapping areas, assessing damage, removing debris, delivering supplies, and evacuating casualties

BotPro

Company that makes robots for various industrial applications
Focused on making rescue robots in the past decade
found that robot performed below expecatations
- trouble navigating throguh factories and reaching the exact location of survivors

What is a GPS?
- Global Positioning System
- According to NASA, GPS is a system of 30+ navigation satellites circling Earth. We know where they are because they constantly send out signals. A GPS receiver in your phone listens for these signals. Once the receiver calculates its distance from four or more GPS satellites, it can figure out where you are.
Why is the accuracy and strength of the GPS weak?
- According to the US Space Force
  - Satellite signal blockage due to buildings, bridges, trees, etc. - buildings surrounds the factories
  - Indoor or underground use - used in factories
  - Signals reflected off buildings or walls ("multipath") - Chunks of debris making it harder

Accurate mapping of the area: reliably operate in a GPS-degraded environment or GPS-denied environment and in the absence of an exact map
- What is a GPS degraded environment?
  - any situation or location where the Global Positioning System (GPS) signals are unreliable, weak
- What is a GPS-denied-environment?
  - a location or situation where the Global Positioning System (GPS) signals are not available at all
Navigation in a dynamic and unknown environment: RR (rescue robot), required to navigate in unknown environments, where structures are damaged and changed
Finding survivors: RR required to detect and differentiate between debris and humnans under different, light conditions, deal with blockages, and recognize deformed shapes
Communication: RR required to communicate with rescue team outside damaged space. may have to rely on large databses and proccessing power of central computers
