Explain Me!

● A Robust Chassis design incorporating the power cells, the basic locomotion control unit, the hubs and traction motors...completely sealed as in dire situations it has to traverse through water puddles.

● We tried to maintain a lower CG by pushing all the heavy stuff towards the bottom so that it does not topple. Note: The Chassis is common for all.

As of now we designed four Vehicle assembly options (with specific traits) that can be mounted on the Base Chassis with ease at the Marine Base Station only before deployment (so technically it is modular & swap-able at the Marine Base).

But we restricted ourselves & made the ROVER a standalone nutcase during rescue operations considering the situational practicality of deployment.

❖ The GUNG HO has to be air dropped to the Rescue site, so the entire frame has to withstand the landing force.❖ The terrain is rugged & non-level hence the frame has to respond to continuous jerks on-route, thus having delicate

access points to win the swap-able criteria might be a disadvantage.

The worst case scenario: If this was one loaded vehicle and was compromised the entire rescue mission would have been jeopardised, no aid would have even reached. But the fleet concept, let's guess the probability of the entire fleet failing all at the same time? We don't know...but at least we know that the probability of success of a 4 member fleet is 4x times higher than the previous generation.

Advantages❏ RESCUE is a Fleet of autonomous ROVERS sent for rescue operations each equipped with

a unique traits for the operations. They have the ability to collaborate & assist each other.

❏ It is equipped with state of the art Equipments and Fusion of inspired Designs from

various domains that makes it a hard nut to crack, even in the worst case scenario.

❏ New high strength materials enable to design a Chassis that is light, durable & strong. It

has to be Robust and thus a blend of Fibre composites & Carbon Fibre structure will be a

phenomenal choice.

❏ This Humanitarian Aid Vehicle is greatly capable of rescuing, operating & supplying

necessary aids to the disaster sites.

DISTRIBUTE SUPPLIES @Cargo

10

● Cargo Capacity: 500 lb (227 kg) or roughly half of a standard Palletized Container (PALCON).

● The floor of the Rescuer is adapted with floor rollers to accommodate these small PALCON’s .

● Compartments have color coded shutters and spacious Bays to facilitate ease and proper storage of cargo.

● Establish Camps & Bases instantly in the affected area.

11

DISTRIBUTE SUPPLIES MRE, Bottle & Kits ...

Automated Distribution of MRE, Water & Kits ...

● Screen Touch sensitive display. When one presses the water / MRE icon, the following are delivered & also their fingerprints are obtained to gather Casualty & Survivor details.

● Additionally, if someone needs extra packet,the machine will do Sentiment Analysis, and ifrequired will deliver additional set.

● This Sentiment Analysis will be use RNN, and would also rely on Natural LanguageProcessing.

12


Automated Distribution of MRE, Water & Kits ...

● The RESCUE, will communicate with the victims in their local language.

● The AI can differentiate between Marine and Victims, based on Image Classification usingSupport Vector Machine (SVM).

● Also when a marine authenticates her/his identity with fingerprint then the RESCUE will give a debrief of the situation.

13


Understanding the Mechanism ...

● The following is inspired from a XY plotter + the reloaded Magazine of Gun. Also refilling of the new crates is much Easier.

● The deliverables i.e MRE’s, Water bottles & Kits are disposed one after another as per the request tokens

● Construction of this Delivery system requires a two Stepper motor setup and Serial Communication.

14

CARRY INJURED The Intense Care POD

Understanding the Design & Usage.

● The POD is equipped with state of the earth Medical equipments like Defibrillator, CPR Kit etc. to facilitate Emergency Operations directly in the disaster struck area.

● This mobile Paramedic Rover is also equipped with portable X-ray machines/ MRI scanners & Vital scanners.

● The POD can operate exquisitely by taking power from the Op-Assist Rover through Fast charging.

15

CARRY INJURED The Intense Care POD

Understanding the Design & Usage.

● The POD when initiated, lowers & extends outwards to facilitate the stretchers

● The Victim is then transferred inside in prone mode, with the stretcher itself and complete rest mode is Activated to avoid additional trauma.

16

CARRY INJURED The Facilities

17

CARRY INJURED Intense Care Stabilization

Concept !

● The following is XYZ vibration compensatory Isolation POD for Critical & Trauma Victims.

● Design Adapted from Airplanes, where we can move freely in three dimensions. A change in any one of the three types of motion affects the other two.

● Roll, Yaw & Pitch compensation using Gimbals & Hydraulic pistons. These are used for creating -ve jerks obtained from gyroscope to stabilize the pod during transport..

How does RESCUE navigate the way?

➢ Computer vision is how cameras are used to see the road. For a RESCUE, camera images are used to find lane lines, or track other vehicles on the road.

➢ Sensor fusion is to integrate data from other sensors, like radar and laser together with camera data to build a comprehensive understanding of the vehicle’s environment. As good as cameras are, there are certain measurements — like distance or velocity — at which other sensors excel, and other sensors can work better in adverse weather. By combining all of our sensor data, we get a richer understanding of the world.

How does RESCUE navigate the way? @LIDAR @ Kinetic Depth Camera

➢ Localization is to map RESCUE in the world, which is the next step after we understand what the world looks like. Using sophisticated mathematical algorithms the vehicle is localized to within 1–2 centimeters.

➢ Path planning Trajectory through the world is mapped to get to the destination and this path is followed to execute the maneuver safely and comfortably.

➢ Control Vehicle needs to turn and hit the throttle or the brake, in order to follow the trajectory.

20

❖ Direct communication between vehicles may be supported by the deployment of mobile ad hoc networks (MANETs), which do not rely on fixed infrastructure and can accommodate a constantly-evolving network topology.

❖ MANETs covers application requirements and communication protocols for everything from sensor networks to handheld computers and vehicle systems.In this scenario, a mobile node will connect with its peer using wireless radio.

❖ The communication will be one to one.

❖ The lead vehicle will set the pace and will communicate maneuvers to the followers.

RFI Communication Protect. How?

21

❖ By using an adaptive space-time array the interference from multiple, strong interferers plus multipath can be canceled down close to the noise floor without producing serious loss or distortion of a GPS signal.

❖ To counter this problem an adaptive antenna array is required because the location of the interference will not be known, a priori

❖ This architecture is a special case of the three-dimensional space-time processor (3D STAP) proposed for radar systems to cancel ground clutter, jammers and jammer multipath.

❖ The adaptive FIR (finite impulse response) filters are able to tailor the response so as to null interference plus multipath over broader bandwidths

Communication Scan & Survey...

22

➔ The drone will scan the environment and generate a 3D model, so that it can give the marines a better feel of the situation.

➔ The RESCUE has an X band low-gain and an X band high-gain antenna for communications to and fro, as well as an ultra high frequency monopole antenna for relay communications.

➔ The low-gain antenna is omnidirectional, and transmits data at a low rate to Base Camp.

➔ The high-gain antenna is directional and steerable, and can transmit data to Base Camp at a higher rate. The RESCUE uses the UHF monopole and its CE505 radio to communicate.
