2.1 Introduction

War bots are a type of combat bots which are custom made bots controlled by remotes mainly made for attacking and now in recent times there are bot fights organized where different countries represent there bots in this tournament . Robot combat involves remotely controlled robots fighting in a purpose-built arena. A robot loses when it is immobilized, which may be due to damage inflicted from the other robot, being pushed into a position where it cannot drive or being removed from the arena. Fights typically have a time limit, after which, if no robot is victorious, a judge or judges evaluates the performances to decide upon a winner.

Different types of bots

1: Drum roller

Spinning drums almost always rotate vertically which means that they can potentially toss an opposing robot upward. The speed at which drums spin can turn the weapon into a gyroscope which can help the robot if one of its drive wheel fails. Drums can be easily implemented into an invertible design. Drums generally have a wider range of attack than other vertical spinning weapons, meaning that they can bite into bigger areas at the same time.

2: Hydraulic bots

Although mechanically resembling a lifter, the flipper uses much higher levels of pneumatic power to fire the lifting arm or panel explosively upward. An effective flipper can throw opponents end-over-end through the air causing damage from the landing impact or, in Robot Wars, toss it completely out of the arena. Flippers use a large volume of compressed gas and often have a limited number of effective attacks before their supply runs low.

3: Spinner bots

Midcutter have a spinner placed about halfway up the robot (usually slightly lower). Undercutters have a spinner low enough almost to scrape the ground. All of these types can use a disc or bar, although bars are usually more effective. Weapons usually spin at a similar speed to verical bars/discs) Advantages of this type of weapon are the large impacts and tendency to throw other robots across the arena floor.

4: Rammer bots

Rammer – Robots employing high-power drive trains and heavy armor are able to use their speed and maneuverability to crash into their opponent repeatedly with the hope of damaging weapons and vital components. Their pushing power may also be used to shove their opponent into arena hazards. Rammers typically have four or six wheels for traction and stability and are often designed to be fully operational when inverted. Because modern rulesets require all robots to have a moving weapon, modern rammers are equipped with other weapon types.

5: Overhead Axe

Overhead Axe – Swinging a high-speed axe, spike, or hammer forcefully down onto your opponent offers another method of attacking the vulnerable top surface. The weapon is typically driven by a pneumatic actuator via a rack and pinion or direct mechanical linkage. The attack may damage the opposing robot directly, or may lodge in their robot and provide a handle for dragging them toward a hazard. Some axes are double-sided, and can strike opponents both in front of and behind the robot

6: Full body spinner

Full Body Spinner – Taking the concept of the spinner to the extreme, a full-body spinner rotates the entire outer shell of the robot as a stored energy weapon. Other robot components (batteries, weapon motor casing) may be attached to the shell to increase the spinning mass while keeping the mass of the drive train to a minimum. Full body spinners require time to spin the weapon up to speed, typically cannot self-right, and can be unstable.

Basic Components Of Combat Bots

Batteries

But in general, most bots by far use Lithium Polymer (LiPoly) combat robotics batteries to power their bots. LiPoly batteries are the battery of choice because of their cost, power capacity, and power to weight ratio.

Chassis

we can use Aluminium sheet for the chassis or instead we can use acrylic sheet for the chassis

Motors

High rpm motors for the drum roller and one set of motors for the drive system. Radio Controller

Attacking Mechanism

there will be two attacking mechanism one drum roller and the other one blades.

Arduino

The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operate. Each of the boards is a full Arduino board programmable using the Arduino IDE.
