Weaponobot is an unmanned ground vehicle that is compatible with all-terrain and combat regions, it establishes peace and control without causing life loss to the soldiers, it is effective in identifying and warning the enemies at first, and also capable of using weapons when situations go wrong, to gain control over the enemies.
The model is an unmanned ground vehicle with an onboard camera and weapon. The robot is powered by the permanent magnet DC motors. Each wheel is powered individually by each motor we can obtain on-demand torque and power which helps for dynamic riding in all-terrain regions. Skid steering is employed for instantaneous turning during combat situations. The motors are controlled by a controller which will synchronously run the system. The controller is integrated into a radio controlling receiving unit. The robot is controlled from the base control station through the radio frequency control unit. The onboard telemetry in the robot will deliver the real-time data of the control system's input and output parameters to the base station.
We incorporated the old flintlock rifle principle for making the weapon. The gun powder is used as a base charge and it is compacted inside the barrel which is ignited with an electric detonator. The electric detonator is made based on the bridge wire detonator concept. The detonator is filled with a magnesium-based flash powder which has more velocity of detonation than that of black powder, so it can trigger the gunpowder inside the barrel causing it to explode thereby building an enormous amount of pressure throughout the barrel that pushes the projectile forward by Imparting kinetic energy to the projectile. The barrel is fixed to a two-axis turret system which is capable of achieving 60-degree pitch and 360-degree yawing. The turret system is coupled to a high gear reduction unit that can withstand the recoil energy produced because of the muzzle energy produced at the end of the barrel, hence giving the ability to trace the motion of the target without compromising the accuracy levels of the weapon. The robot is designed to carry a payload of 150 kg, which can be useful for carrying the necessary cargo of the troops with ease. And it also helps to transport injured soldiers to safe zones during the combat scenarios.
The robot is powered by lead-acid batteries. The idea is to implement the hydrogen fuel cell methodology for meeting the energy needs of the robot. As of now, our model is powered with lead-acid batteries, lithium-ion, and lithium polymer can also be used for the power source. The robot contains a waypoint navigation system integrated with GPS, which will facilitate to make autonomous missions, and live positioning of the robot can be obtained. The Improvised explosive devices (IEDs) and landmines can be identified by the robot during its traveling on the ground by the electromagnetic signature recognition unit. and after the identification of the IED, the coordinates of that place are sent to the base station. so that the IEDs and land mines can be neutralized with no human loss. Due to restrictions, we didn’t have access to present existing ammunition and weapons we made the muzzle loading rifle and integrated it with an electronic detonation system to the vehicle. But if we had access to the normalized rifles and weaponry, we assure that we can able to produce a fully modified robot with advanced machinery, and weapons and make the mighty Indian army much more powerful than any other.
Before converting our idea into a model our team visualized each and every individual component by modeling in CAD Software. once after analyzing all the individual components that are designed by our team, are integrated to form a complete and well-designed model which resembles the exact idea that we assumed. when it comes to fabrication we selected suitable materials that fit our purpose. once acquiring all the material we cut, welded, and framed as per our design. After that, we integrated all the electronics and hardware and gave life to our model.
It took nearly two months to analyze the idea of the model, design requirements, material selection, tool requirement, and gathering of necessary hardware equipment, and also we designed our model in the design software. Once after acquiring all the things that we needed we build our model within a month, so it was around three months for converting our idea into a successful working model.
