Robotics  a friend for assisting handicapped people-(s.surya,s.vidhya) Robotics a friend for assisting handicapped people-(s.surya,s.vidhya) Presentation Transcript

  • PRESENTED BY D.KAVITHA III BE ECEJAYARAM ENGINEERING COLLEGE OF TECHNOLOGY
  •  Developed at the University Bermen’s Institute of Automation(IAT) Offers increased control functionality for the disabled users Robot arm MANUS was specially designed for people with upper-limb impairments
  •  Electric wheelchair Robot arm MANUS Dual Pentium PC CAN-bus RS-232 interface Tray and flat LCD display Mini camera Speech recognition software Arm controller
  • THE ROBOTICS SYSTEM FRIEND
  • ARCHITECTURE OF THE SYSTEMFRIEND
  •  Programming may be done using either  Teach-in procedure  Robot Programming by Demonstration(RPD) Control  By user  Autonomous control by the system
  •  Programmer demonstrates task to be executed with his own hand Motions are measured, recorded and processed Measurements are not used in simple pick and place Used to execute complex trajectories without difficulty inspite of variable initial conditions
  • DEMONSTRATION
  • POURING A GLASS
  • EXPERIMENTAL RESULTS
  •  FRIEND uses a grasp utility- labeled objects Visual servoing with a gripper-mounted camera is used along with TbS To grasp the same object the gripper is moved to taught grasp position. It may be manually done or automatically done.
  • START AND END OF PICK ACTION
  •  Computes the change in position of the robot In new position control algorithm is used to reach the taught relative position A controller must  Drive the gripper from any reasonable starting position to the gripping position  Must ensure that the object marker remains in the image during the motion
  • Positioning the wheelchair too Grasping without collision from a close to the object causes surface (optimal) wheelchair collision with the shelf. location.
  •  Laborious Time delay in speech recognition system Improvement arises with semi-autonomous actions Research and development is still required Future work will focus on  Analysis and implementation of semiautonomous actions  Simplification of MMI  Improvement of the safety functions
