ppt on rocker bogie mechanism

  1. 1. Project Title :- Rocker Bogie Mechanism (rover)
  2. 2. Introduction  Mobile Robots and Description of “Rover” :- “A mobile robot is an autonomous system capable of traversing a terrain with natural or artificial obstacles. Its chassis is equipped with wheels/tacks or legs and possibly a manipulator setup mounted on the chassis for handling of work pieces, tools or special devices. Various preplanned operations are executed based on a pre-programmed navigation strategy taking into account the current status of the environment.” This definition any intelligent machine which moves with respect to environment within limited human interaction (autonomously) called “Mobile robot”.
  3. 3. Mobile robots can be classified by significant properties:- • Locomotion (Legged, wheeled, limbless, etc.) • Suspension (Rocker-bogie, independent, soft, etc.) • Steering (Skid, Ackerman, explicit) • Control Algorithm (Fully-Autonomous, semi-autonomous) • Body Flexibility (Unibody, multibody) • Usage Area (Rough Terrain, even surface, etc.) • Guidance and Navigation (Star field or Sun detection, GPS, sensor-based)
  4. 4. Locomotion Locomotion is a process, which moves a rigid body. There is no doubt that a mobile robot’s most important part is its locomotion system which determines the stability and capacity while traversing on rough terrain. The difference of robotic locomotion is distinct from traditional types in that it has to be more reliable without human interaction. While constructing a robot, designer must have decided on the terrain requirements like stability criteria, obstacle height, and surface friction. There is no only one exact solution while comparing the mobility systems.
  5. 5. Mobile robots can be used in several applications. Dangerous area operations (Nuclear plants), planetary exploration and pipe investigation, extreme temperature and narrow field investigations (pyramid exploration robots). Moreover, floor cleaning robots and servant robots are common examples for indoor use. It is not a dream that, in near future robots will be a part of our daily life.
  6. 6. History of Rovers Sojourner examining the rock named “Yogi”
  7. 7. The first planetary exploration rover was “Lunakhod” which has been sent Moon 2 times with USSR – Luna missions to gather information around landing site and send pictures of terrain.
  8. 8. Inflatable rover with 1.5 meter wheel diameter
  9. 9. NASA Sample Return Rover (SRR)
  10. 10. Mars Exploration Rovers (MER)
  11. 11. Legged robot Wheeled robot
  12. 12. Hybrid Robots
  13. 13. Objectives of the project The objective of this project is to design a small, robust and highly maneuverable rover robot. It will be designed for working on the different platforms like rough terrains, smooth surfaces, overcoming obstacles in its path and climbing over obstacles of certain height, choosing different predetermined gaits and to have good stability, speed as well as payload capacity.
  14. 14. Rocker and Bogie Mechanism
  15. 15. Bogie Overturn Problem There are several forces act on wheel on x axis. If the surface friction of an obstacle is not enough to climb, obstacle force (Fobs) can reach high values. This problem can also occur while middle wheel actuator failure. Driving velocity is also restricted by bogie overturn problem.
  16. 16. Rocker Bogie Suspension robot
  17. 17. Working Principle of Rocker Bogie robot • Another challenging terrain type for mobile robots is step climbing. For indoor usage, stairs are the most significant obstacles. This vertical motion also needs high surface friction coefficient between wheel and ground.
  18. 18. Application of Rover robots • Mobile robots can be used in several applications. Dangerous area operations such as, • (Nuclear plants), planetary exploration and pipe investigation, extreme temperature and • narrow field investigations (pyramid exploration robots). Moreover, floor cleaning • robots and servant robots are common examples for indoor use. • It is not a dream that, in near future robots will be a part of our daily life
  19. 19. Military: The main application in military is when traveling on soft ground or rough terrain. The source of the most sustained interest in this application is the US army, which had supported the research in rover machines. In particular the OSU’s Adaptive Suspension Vehicle is a prototype rough country vehicle.
  20. 20. Mining: Robots are used in mining because of their capability to move on steeper slopes or even bracing the roof. There are also deep mining robots, which can be controlled remotely rather than autonomous.
  21. 21. Bomb Inspections
  22. 22. Planetary Exploration: Space travel and robots are twin pillars of science fiction long before they were actually used. Legged robots provide greater flexibility and offer better mobility on the loose, steep and rocky surfaces on the Moon and Mars.
  23. 23. Mobile robots in Artificial Intelligence: Artificial intelligence is related to testing of theories and programs as related to the real world. Robots are useful for testing theories because they force the designer to deal with the complexity and untidiness of the real world. Artificial intelligence includes Perception of noise signals, voice recognition, vision systems and sensors.
  24. 24. Conclusion We can develop this mechanism to create wonders and can be used in almost all our related fields. We have tried our best to make this project much more economical and efficient.
  25. 25. THANK YOU
