Line diagram of Chassis This is made in to get bot move on all terrains smoothly. For this a different kind of shock absorbing system or terrain adjustment system is used. MechanismThe bot has two base which can move clockwise and anti clockwise thus when an obstacle comes below any base, then that base lifts up but leaving the other base unmoved thus the bot climbs over the obstacle. The two parts rotate separately when any obstacle comes below.

Thus create a shock absorbing system. By this mechanism bot get flexibility over rocky surfaces as front chassis and rear one can rotate independently.

In this design, in order to get ground clearance the side walls are elongated. It will be made of plywood for strength. The main benefit of this design is that it brings flexibility in bot without compromising stability.

Lifting mechanism: This is a very important part of our machine which is to lift joints and victims. Here we using 2 rods, the first is connected to rotating base with motor to extend it to reach the hooks on joints and victims. The other one is again joined to the first with another motor for lifting the joints and victims. The use of rotating platform is to place victims in a carriage (in next image) on the rear part. This is done to carry multiple victims at a time.

For locomotion bot as well as for working of crane, we using electric energy and will be using high torque motors. A remote controlled electronic relay system PCB will be fixed on the Rear platform.

INSTRUMENTS USED: 1. 2. 3. 4. 5. 6. 7. 8.

4 motors for locomotion 3 motors for crane 1 hook Electric circuit with relay. Gears to obtain required torque and RPM DPDT switches Wires(including jumper wire and bus wire) DC 12V BATTERY
