OVERVIEWThe chassis is composed of a basic differential drive. The tyres used are bigger than the normal ones to provide better handling on uneven surfaces. On the chassis are placed an uprising vertical support to place a pulley and a separate motor to control the movement of the arm. By the movement of the motor 1 shown, a pulley is rotated such that a wound thread and thus a hook can be lowered or raised up.
Positioning of motor 1
Motor 1 is placed at a level higher than the base of the chassis to control the motion of a pulley and thus a wound thread. This thread is in turn connected to a hook which can be used to lift victims and joints. This higher level is achieved by help of a uprisen platform.
MOTOR 2 Motor 2 is used to control the horizontal motion of the hook by moving the arm. It facilitates the picking up of joints or victims and their exact placement over gaps or in the safe zone.
WORKING The victims picked up are placed on the bot itself to facilitate easy carrying of more than one victim at a time. These are then dropped off at the safe zone.
