  1. 1. BEAM ROBOTICS<br />PRESENTED BY,<br />RAJIV R<br /> 1Y06DEC051<br />
  2. 2. This presentation will include…<br />Introduction to Digital Robotics.<br />Kinds of Digital Robots.<br />Strengths and weaknesses of digital robotics.<br />Introduction to BEAM robotics. <br />Strengths and weaknesses of BEAM robots.<br />Design.<br />Performance of BEAM Robots <br />
  3. 3. Digital Robotics<br />
  4. 4. Introduction to Digital Robotics<br />Programmed with If/Then statements, providing criteria and appropriate, pre-set behavior for each situation.<br />Any defects in sensors used leads to malfunction. <br />Examples: QRio (Sony), Asimo (Honda)<br />
  5. 5. Kinds of Digital Robots<br />Entertainment (example: Sony Aibo or QRio)<br />Industrial (example: painting and welding arms)<br />Special-Effects (example: Jurrasic Park Dinosaurs)<br />Research-based (example: Mars Rover, Honda Humanoid)<br />
  6. 6. Digital Robotics<br />Strengths<br />Precise, controllable movements.<br />If/Then statements dictate exact behavior.<br />Can repeat same task over and over.<br />Weaknesses<br />Can only deal with predicted events.<br />Less scalable technology.<br />Requires massive computing power for simple tasks.<br />Usually not self-contained. (separate computer)<br />Cannot function if damaged.<br />Not suited to natural environment.<br />
  7. 7. BEAM Robotics<br />
  8. 8. Introduction to BEAM Robotics<br />What it means: Biology, Electronics, Aesthetics, Mechanics.<br />Design philosophy: Simplest possible design to perform a specific task. (No unessential features).<br />Uses no programming.<br />Mimics organic life.<br />Actions dictated by physical design.<br />High survivability.<br />
  9. 9. Different types of BEAM Robots.<br />AUDIOTROPE-which reacts to the sound sources<br />
  10. 10. RADIOTROPE-which reacts to the Radio frequency sources.<br />
  11. 11. PHOTOTROPE-which reacts to light sources.<br />
  12. 12. THERMOTROPE-which reacts to heat sources.<br />
  13. 13.
  14. 14.
  15. 15. BEAM Robotics<br />Strengths<br />Adaptable behavior to fit situation.<br />Energy efficient.<br />Durable.<br />Renewable power source.<br />Adaptable to damage.<br />Protects self.<br />Can survive outside laboratory environment.<br />Weaknesses<br />Random behavior.<br />Not as taskable.<br />Inexact movements.<br />Not suited to “factory” environment.<br />Reflexive.<br />
  16. 16. Simple autonomous Robot-RADIOTROPEIMPLEMENTATION<br />
  17. 17. Design<br />4 limbs.<br />2 solar cells i.e 1 for use and one for backup.<br />RF sensor i.e only to sense the enemy signals.<br />Neural networks to avoid collision<br />Wireless camera.<br />A position locater to locate the robot.<br />
  18. 18. ARITIFICIAL NEURAL NETWORKS(ANN)<br />An artificial neural network is composed of many artificial neurons that are linked together according to a specific network architecture<br />Neurons mimic the properties of biological neurons.<br />Each neuron of an artificial network learn from the environment in which robot is left.<br />
  19. 19. ANN-implementation<br /> try to create an learning environment which comprises of enemy TX, host TX and actual war field environment.<br /> make neural networks to learn in this environment and make motors(which drives the wheels of robot) to run according to knowledge gained from neurons. <br />Now the robot is left in the war field to find enemy TX.<br />Robot reach the enemy TX without any collision due to neural networks implementation.<br />
  20. 20. LEARNING ENVIRONMENT<br />Gaining Knowledge about <br />Surrounding environment<br />Robot-env 4<br />Robot-env 2<br />ENEMY TX<br />HOST TX<br />Robot-env 3<br />Robot-env 6<br />Robot-env 1<br />Robot-env 5<br />Learning process is completed <br />
  21. 21. Robot specifications<br />Low charge<br />Solar cell 1<br />Solar cell 2<br />radiotrope<br />Charging <br />Navigation of robot using neural netw<br />Position Locater<br />
  22. 22. Enemy tx.<br />RF SIGNALS<br />Enemy signal<br /> detected<br />radiotrope<br />our tx.<br />RF signals<br />Missile launcher<br />Position obtained <br />
  23. 23. Performance<br /> Dependabilty of BEAM<br /> Robots<br />Dependabilty of DIGITAL<br />Robots<br />Advancement in the field of BEAM Robotics<br />
  24. 24. Conclusion<br />The application of BEAM robots will be most effective for defence purpose.<br />Navigation of robot is more accurate by using ANN.<br />The end product is reliable and efficient.<br />
