OVERVIEW
Below is a quick overview of the entire project broken up in segments.
HUMANITARIAN DEMINER
Our product is a low-cost machine that safely neutralizes anti-personnel mines. Our design will consist of a roller attached to a modified pre-purchased off-road vehicle. The machine will apply force to mine fuses causing their detonation as it moves across the terrain.

CONCEPTS
The mechanism and method by which the deminer will effectively render an AP mine harmless.
The mechanism will apply a force that will detonate, destroy, or deactivate AP mines. i.e. flail, tiler, roller, etc...

METHODS OF LOCOMOTION AND PROTECTION
The main component that generates power and delivers it to the road surface, or air. i.e. gas, diesel, solar, etc...
The method that the deminer will use to transport itself from place to place. i.e. Pneumatic tires, Solid tires, Continuous tracks, etc...
The methods by which we protect our machine from the impact of anti-personnel mines. This is meant to protect the internal parts of the vehicle driving the demining device.

CONCEPT AND VEHICLE SELECTION
The vehicle selection process was to select a vehicle from a vendor that met the specifications and selection criteria, in order to drive the roller mechanism along its path. Research was put into varying vendors (John Deere, CAT, Bobcat, etc.) and different kinds of vehicles, mostly centering the focus on tractors and loaders, for their high tractive force and modifiability. The choices were narrowed down to four varying vehicles, each from different vendors.

HITCH, FRAME, AND ARMOR DESIGN
The design of the hitch connects the frame of the vehicle to the frame of the roller. The hitch consists of a heavy duty block and plate with a heavy duty 2” ball trailer hitch.
The roller frame will serve as the main connection between the steel rollers and the vehicle driving them. It will be made completely of A36 structural steel.
The armor was designed to be able to protect the selected vehicle and also any other vehicle that
is to be pushing the deminer because it will be attached to the frame.

ROLLER ASSEMBLY DESIGN
Fastened to the frame will be two arrays of swivel casters. The caster wheels will be removed and replaced with the roller arm to connect the steel rollers to the frame.

STRESS ANALYSIS
Stress analysis was performed to insure all parts will stand up to any situation they will encounter when traveling across tarrain and detonating AP mines.
