4. haptic robotic arm
- 1. “The principal goal of education is to create men and women who are capable of doing new things, not simply repeating what other generations have done.” -Jean Piaget
- 2. HAPTIC ROBOTIC ARM Haptic is the science of applying touch sensation and control for interaction with virtual or physical applications. In combination with a visual display, haptic technology can be used to train people for tasks requiring hand-eye coordination, such as Robotic Tele Surgery and Space-ship maneuvering. It can also be used for games in which you feel as well as see your interactions with images. The Dexterous Hand (from the NASA’s collection of Humanoids) has haptic sensors embedded in every joint and in every finger pad which relay information to a central computer for processing and analysis. In this workshop we train the students to control a Robotic Arm using Haptic Technology (Haptic Glove). COURSE DETAILS OF THE WORKSHOP: Session 1: (4hrs) ADVANCED ROBOTS What is an Exoskeleton? What is Haptic? Applications of Haptic?
