VR BASED ROBOTIC

ARM TRAINING SIMULATION

Introduction

Researchers at Institute for Plasma Research (IPR) are developing the Steady State Superconducting Tokamak (SST-1) to conduct various experiments on plasma matter. In order to perform maintenance operations for the tokamak, the machine has to be brought to a state where it can be operated on by personnel safely. This involves shutting down the entire machine for it to cool to a manageable temperature, breaking the vacuum of the plasma chamber and (sometimes) waiting for radiation to reduce. This lengthy procedure is followed by an equally time-consuming process to bring it back into an operating state. Remote operations for maintenance will reduce the maintenance delays, and allow for longer experiments.

About the Project

A robotic arm is being designed for performing such remote maintenance operations for SST. We have developed a gaming simulation in order to aid the designers in eliciting requirements for their design, as well as helping train operators to perform maintenance operations. We have done this using an immersive virtual environment completely modelled after the SST. Equipment and processes in hazardous and highly specialised environments, which require human input, can be designed, developed and tested using such immersive gaming simulations.

Process
Why VR?

Virtual Reality is the representation of a real or imagined world through electronic means, which provides the feeling of being in a real situation and where you can interact with its components.

 

It can be defined as a synthetic or virtual environment which gives a person a sense of reality. It comprises a range of computer technologies that present information in a form that people perceive as similar to real world.

Through 3D computer graphics via advanced input and output devices, users believe they actually perceive sensory information that is similar to that of the real world.

Research
Categories

Research included understanding VR, its categories, issues, principle feature and types of interaction.

 

 

Virtual Reality is a concept that encompasses complex notions, mechanisms,  technologies resulting from the interaction of a wide range of field of study of:​​

  • Immersion

  • Presence

  • Interaction

  • Technologies

 

 

 

VR can be classified into Three Categories:

  • Immersive

  • Semi-Immersive

  • Non-Immersive

 

 

 

VR simulation may have advert effects as users may experienced “cyber-sickness”.Studies have shown that exposure to rotational motions in a virtual environment can cause significant increases in nausea and other symptoms of motion sickness. This effect is made more acute as all external reference points are blocked from vision. 

 

 

 

Two principal features of VR are

  • The user can control the viewpoint in the Virtual Environment with six degrees of freedom
  • ​The user can interact with objects within the Virtual Environment.

 

 

 

 

 

 

 

 

 

Interaction in VR involves advance technologies like:

  • Motion Tracking ​

    • Gesture Recognition de​vices.

  • Haptic

  • Gaze tracking 

  • Voice Command

Implementation

To design a VR game simulation in order to aid the designers in eliciting requirements for their design, as well as helping train operators to perform maintenance operations. I was involved in initial phase of this project where my role was stimulate the arm movement of the robot.

Due to the confidential nature of this project and an NDA with Fields of View, I would not be able to share any further details on this platform. We could however discuss the same offline.
