Robotic Arm Manipulator with Haptic Feedback Using Progammable System on Chip (PDF)

Bachelor Thesis from the year 2012 in the subject Engineering - Robotics, grade: A, National University of Sciences & Technology (NUST School of Electrical Engineering and Computer Science), language: English, abstract: Haptic Feedback systems are used to sense the vibrations, touch and force in many real world problems for example gaming, virtual reality, mobiles, automotive industry and robotic surgery. Our work involves the design and development of a robotic arm at slave end which includes force and current sensors that allows the operator to get force feedback at the master end. Three methods of feedback are generally used i.e. Force Sensitive Resistors for object detection, Current Sensing for force feedback and Position estimation to replicate motion. The three mentioned methods are analyzed using graphs developed on the PC.
Graphs are obtained by experiments on the gripper by using different objects. Master-Slave topology is used to attain some benefits over conventional control systems in term of ergonomics, accuracy and timing etc. There is an interactive GUI at master end to show us forces, size and motions at each joint of the slave unit. Along with the interactive GUI at master side, yaw and pitch motion of slave is also replicated at master end using master controller
