Humanoid robots

  1. 1. Humanoid Robots : ASIMO Guided by : Presented By: Tejas RajgureProf. S. A. Deshpande Roll no. 48
  2. 2. Outline What is a robot? History of robots Our Times Why Humanoid Robots? ASIMO Recognition Technology in ASIMO Conclusion References
  3. 3. What is Robot?? “A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks." - Robot Institute of America, 1979 An Intelligent robot is a mechanical creature which can function autonomously”
  4. 4. History Early Stages  The notion of putting machines to work can be credited to great thinkers like Aristotle. Westinghouse Electric Corp. creates two of the first robots that use the electric motor for entire body motion.
  5. 5. History (cont.) 1968…’Shakey’ build at Stanford Research Institute. Shakey could perform tasks that required planning, route-finding, and the rearranging of simple objects.
  6. 6. Our Times In 1997 the P1 robot was produced by Honda which was more human like. Capabilities:-  Walk around  Climb stairs  Carry things  Pick things up  Push things  Position it self accurately
  7. 7. Our Times (cont.) In 2000 Honda incorporated the P3 technology into its dancing robot ASIMO.
  8. 8. Why Humanoids?? Are there any good reasons for doing research on humanoid robots?  Work in dangerous environments  Exhaustive and repetitive tasks.  Division of labor with humans in cooperative tasks  Anthropomorphism  Embodiment  Interaction and Communication
  9. 9. Why Humanoids?? Anthropomorphism  Humans have built complex environments, tools and equipments very much adapted to our selves.  Robots with human-like morphology and motion capabilities have a greater potential acting in living environments created for humans, than e.g. wheeled robots.
  10. 10. Why Humanoids?? Embodiment  The form of our bodies is critical to the representations that we develop and use for both our internal thought and our language.  If we are to build a robot with human like intelligence then it must have a human like body in order to be able to develop similar sorts of representations.
  11. 11. Why Humanoids?? Important aspects of being human are interaction and communication with other humans.  Humanoids can communicate in a manner that supports the natural communication modalities of humans. Examples include: facial expression, body posture, gesture, gaze direction, and voice.  If a robot has humanoid form, then it will be both easy and natural for humans to interact with it in a humanlike way.
  12. 12. Who is ASIMO? ASIMO is a humanoid robot created in 2000 by Honda. ASIMO stands for  Advanced Step in Innovative Mobility 11th in line of successive bipedal humanoid model’s by Honda. It is the 4th man like humanoid robot.
  13. 13. SpecificationsWeight: 52 kilogramsRunning Speed: 6 km/hWalking speed: 2.7 km/hWalking speed while carrying objects: 1.6 km/hHeight: 130 cmWidth: 45 cmDepth: 44 cmContinuous operating time: 40 min – 1 hr.Degrees of Freedom: 34
  14. 14. Why was ASIMO created?
  15. 15. Why was ASIMO created?
  16. 16. Why Legs for Humanoids ? Potentially less weight Better handling of rough terrains Only about a half of the world’s land mass is accessible by current man built vehicles Do less damage to terrains (environmentally conscious) More energy-efficient Use of isolated footholds that optimize support and traction (i.e. ladder) Active suspension Decouples the path of body from the path of feet Exploit discrete footholds
  17. 17. Why Bipeds? Why 2 legs? 4 or 6 legs give more stability, don’t they? A biped robot body can be made shorter along the walking direction and can turn around in small areas Light weight More efficient due to less number of actuators needed Everything around us is built to be comfortable for use by human form Social interaction with robots and our perception Our instinctive desire to create a replica of ourselves
  18. 18. Walking vs. Running Motion of a legged system is called walking if in all instances at least one leg is supporting the body If there are instances where no legs are on the ground, it is called running Walking can be statically or dynamically stable Running is always dynamically stable Airborne time for ASIMO 0.08 sec.
  19. 19. Honda’s Dynamic Stability Controller  Keep foot flat on the ground (fully actuated)  Estimate danger of foot roll by measuring ground reaction forces  Carefully design desired trajectories via optimization  Keep knees bent (avoid singularity)  Adaptive trajectory tracking control (high feedback gains)
  20. 20. Walking - further challenges Can’t compete with humans in terms of: – Speed (0.44 m/s top speed) – Efficiency (uses roughly 20x as much energy per unit weight, per distance moved) Robustness (Cant perform fast actions as humans) DC electric motor runs Hot
  21. 21. Recognition Technology With 2000s ASIMO model Honda added many features, labeled "Intelligence Technology", that enable ASIMO to interact better with humans. These features fall under 5 categories: 1. Recognition of moving objects 2. Posture/gesture recognition 3. Environment recognition 4. Sound recognition 5. Face recognition.
  22. 22. Recognition of moving objects ASIMO can detect movement of multiple objects, assessing distance and direction using the visual info. captured by the camera. Featured served by this application are  Follow the movements of people  Follow a person  Yield to pedestrians in its path.  Greet a person when he or she approaches.
  23. 23. Recognition of postures and gestures  Positioning and movement of a hand, recognizing postures and gestures.  Can react and be directed to both voice commands and natural movements of human being.  Recognize when a handshake is offered.  A person waving at it.  Movement directions.
  24. 24. Environment recognition ASIMO can recognize the objects and terrain of his environment and act in a way that is safe for both himself and nearby humans.  Recognizing potential hazards such as stairs.  Avoid hitting humans and other moving objects.
  25. 25. Distinguishing sounds ASIMO can distinguish between voices and other sounds. He can respond to his name, face people when being spoken to, and recognize sudden, unusual sounds such as that of a falling object or a collision, and face in that direction.
  26. 26. Facial recognition ASIMO has the ability to recognize faces, even when ASIMO or the human being is moving. It can individually recognize approximately 10 different faces. Once they are registered it can address them by name.
  27. 27. Demo ASIMO working as a Bartender.
  28. 28. Conclusion Robots are taking over tasks which are deemed dull, dirty and dangerous The idea of robots with greater intelligence than humans is at least 50 years away, and may never come Its not the robots we need to worry about; its the people who program them. Humanoids can be used as workers at Exhaustive task.
