I-cat . The mine detector robot

The bot is specially designed for robo minesweeper event. The bot construction remains same as the racing bot but this bot has a special mechanism for detecting and picking up the mines(metal plates). the bot has a movable electromagnet mounted on the arm on its top. The arm is operated by a high power motor which can lift higher weights also. The electromagnet has a separate switch which helps to operate it whenever required. When the electromagnet is turned on the arm lifts up the plate. There is an additional hydraulic mechanism to dump the lifted mines mounted on the top of the arm.

Racing robot i-cat- antiflipper

This is the Robot designed for racing. It is driven

by four motors in each of four wheels. The wheels used are of larger diameter so as to cover more distance in short time . The robot is called antiflipper as it is designed in such a way that it can run as it was even after flipping for example after falling from height. The chassis is made a bit heavy as to get easy control on the bot.

High power WAR robot- "OPTIMUS"

This is my high power robot designed for robowars. The motors used have high speed reducing worm gears to deliver higher torque. The robot has a driving shaft and the power is transmitted to other shaft using chain and sprocket. There is a rammer in the front and a wedge at the rear which act as weapons.

Racing robot with chain link

This is my new racing robot which is highly accurate and fast. It uses a belt nd chain drive . there are four motors at each of the wheels which power them. the wheels are very small i.e 40 mm diameter and are designed out of high quality teflon. it operates on 12 volt supply.

War robot using chain-sprocket as a drive

The robot is a four wheeled robot designed for wired control. The bot design is completely metallic with all the components mounted on a metallic chasis. The bot design is divided into basically two different components. One is the Driving Mechanism and the other is the Weaponary Component.

Driving Mechanism:
This mechanism is incorporated primarily for motion of the bot. With the help of this mechanism the bot is able to move forward, backward and turn within the arena. The concept of Differential Steering, similar to that in tanks, is used for steering. The tracks are made to move at different speeds or even in opposite directions to bring about a change of course .The construction of this mechanism includes distributed power transmission to all the four wheels by using chain and sprocket drive. This enables the bot for effective turning in a short time and better traction.
Weaponary Component:
The Weaponary Component consists of prominently two weapons. The Rammer and the Lifter or Flipper.
Rammer:
The bot design consists of four Rammers, two located on the front side of the bot and two on the rear side of the bot. The function of this mechanism is to push the opponent’s bot out of the arena. This mechanism consists of movable rammers which are located inside the bot prior to activation. Once activated they come out linearly out of bot and help pushing opponents bot if targeted properly. Its more effective when it’s used in combination with driving mechanism. The use of two rammers in front and rear avoids the necessity of turning when the bot attacks from behind. Also this mechanism keeps the opponent’s bot away and serves as an effective armor.

Lifter(Flipper):
This is another weapon included in the bot design. The primary function of this weapon is to reduce the traction of the opponent’s bot thereby attacking its strength and mobility. The design of this weapon consists of a protruding part coming out of bots body. During combat first this protruding part is initiated to attack the ground clearance of the opponent’s bot. Now the weapon is activated which lifts the opponent’s bot partially or completely above the arena (depending on the opponents weight). This reduces the opponent’s traction and to some extent its mobility thereby making it destabilized. If lifted to a proper inclination and used in combination with driving mechanism it can also flip the opponent’s bot.

Hey check out my recent WAR ROBOT which participated at QUARK 11 held at B.I.T.S GOA campus. this is simple in design and we have stressed more on "keep it simple rule". there is no such mechanism to damage the opponents bot. only two rammers in the rear and the front have been added. The turning mechanism is differential. For better ground grip instead of wheels belt drive is used. The robot had an excellent torque because of high velocity ratio of 125:1. The power source for this robot is 12v 100amp battery. The speed of the motor is reduced from 12500 rpm to 1500 rpm using a spur gear and then further to 100 rpm using a worm gear.
