The Rocker Bogie Mechanism: Design and Fabrication

摘要

The Rocker bogie mechanism is a mechanism primarily used in Mars's rovers to overcome the rough terrains while maintaining stability. The rocker-bogie mechanism is just like a climbing robot-type mechanism. It is NASA's important mechanism for space vehicles & rovers. Rocker bogie has the simplest design and the number of wheels is also less. The model is made to travel the obstacle up to a tilting angle of 35. This enables to have a suspension-based mechanism that distributes the vehicle load evenly not only on regular but also on bumps and irregular surfaces. The design consists of a spring-free suspension-based differential drive system that allows the bogie to move over rocks, pebbles, and some obstacles. The main gun mechanism adjustment is done with help of a 30 RPM and 60 RPM gear motor and with help of a compressed spring. As the tank's main gun mechanism rotates 360 just like our steel shaft will rotate, so it becomes very easy to throw the ball at any degree angle, and as the project will move on a rough surface like a military tank so it will give military application (Defense Purpose). The main gun mechanism rotates one or more steel sprockets which move a track made up of hundreds of metal links.
