1.1 Concept of robot:
After studying various methods to climb a rope or rod, we came to conclude that a coconut tree climbers method was the best suited for the job. It resembles the motion of a sloth. It uses both pairs of its limbs (fore limbs and hind limbs) to climb a rope and a tree. It moves both its hind limbs in one step and then both its fore limbs in another. Each pair of limbs acts as a gripper. Only one pair of limbs is used at a time for gripping the tree (while in motion) while the other pair slides over the tree.
The tree climber uses its back as a hinge, the back being straight in one instant and bent in the other. This movement when coordinated can be a very efficient and a reliable mechanism for climbing.

First, the robot must be able to climbing up and down a medium size rope. Secondlythere will be two mode of operation which include automatic mode and manual mode.
For automatic mode, the robot will be operated automatically based on the specifiedinstruction set of program burned into the chip. While for manual mode, the robotmovement will be determined by the user using a controller
1) In case of a fire, firefighters can use it to deliver gas masks or any other emergency medical items at any floor through any window.
2) It can be used for domestic purposes in a building (transporting some light materials to a floor or house below or above it)
3) Research work in dangerous places. Whenever climbing up or down by a person possesses any risk, this robot can first be used to check the safety of the place or to do some of the research work (for example: Speleologists can use this device before actually going in some cave to check for any poisonous gases or any life …show more content…
Weight of the robot: The robot has to carry yourself and extra payload, hence we have to make the robot as light as possible yet durable. The factors that mainly contribute to weight of robot are: servo motor weight , servo strength, power supply, frame, electronic circuitry.
2. Gripping the rope: There are tons of varieties of grippers available in market but most of them are for heavy industries and they are way too expensive for this project. Finding the correct gripper that provides safety, and is cheap was a difficult task.
3. Finding the correct motor: The task could be achieved by using both dc motor and stepper motor too. They would have been a cheaper option but then we would have to compromise on other issues like controllability, efficiency and accuracy.
SOLUTION TO THE ABOVE PROBLEMS :
1. Weight of the robot: we decided to reduce the weight of the robot by reducing the number of arms and type of gripper. The robot will have only two arms.
The motor we will use will have less RPM but more torque (done by using gears). Wherever possible we will use plastic gears instead of metal without compromising on the stability and
