Experience in developing VR simulators in 2021 based on HTC Vive. Part 2

Once again, I welcome Habr readers. I continue to share my experience in the process of creating VR simulators developed by our team this year.

The first part

A few days ago, our team returned from Vladivostok. Successfully delivered to the customer and passed all tests virtual welding simulator.

Unity was chosen as the base. As a VR – HTC Vive Cosmos Elite + 3 Trackers.

The tracker pins on the semi-automatic holder are connected to the start button.

Tasks set:

• study of the functionality and basic principles of operation on a welding machine
• training in practical rules of using welding equipment
• reproduces the process: manual arc welding
• Reproduces the process of: semi-automatic welding
• automatically generates statistical data on the result of performing exercises

The appearance of the equipment in VR

Hardware Component Requirements:

• swivel bracket for camera placement
• fasteners for electrode holder and burner
• mask mount
• rod for fixing the workpiece, height adjustable
• workpieces for welding
• rack
• electrode holder and burner
• mask with built-in 3D glasses

HTC VIVE Cosmos Elite as a “base”An example of using the simulator in the “semi-automatic” welding mode. Manual “welding”

Required features:

• visualization of welding machine operation
• realistic simulation of welding sound in the virtual world
• simulation of welding machine operation
• coordination of the virtual scene in real time with the effects of the trainee on the controls
• display on the monitor screen of the current parameters of the simulated welding process
• statistical processing of results
• studying a virtual welding seam after completing the exercise from different angles and different distances
• the ability to choose exercises from a set
• the ability to choose a workpiece for welding
• display of the welding process in three-dimensional space using: virtual reality glasses, computer monitor
• change the current strength for manual welding
• change the wire feed speed for semi-automatic welding
• get basic motor skills of ignition and maintenance of the welding arc
• location simulating a welding room
• simulation mode of the flow rate and electrode change in manual arc welding mode
• formation of statistics on the results of exercises

List of training exercises for practicing the accuracy of movements

• Exercise #1. Welding seam surfacing in the form of two horizontal lines
• Exercise #2. Welding seam surfacing in the form of five horizontal lines
• Exercise #3. Welding seam surfacing in the form of two vertical lines
• Exercise No. 4. Welding seam surfacing in the form of five vertical lines
• Exercise #5. Welding seam surfacing in the form of a square
• Exercise No. 6. Welding seam surfacing in the form of two nested squares
• Exercise No. 7. Welding seam surfacing in the form of a diamond
• Exercise No. 8. Welding seam surfacing in the form of two nested diamonds
• Exercise No. 9. Welding seam surfacing in the form of a circle
• Exercise No. 10. Welding seam surfacing in the form of two nested circles
• Exercise No. 11. Welding seam surfacing in the form of a sinusoidal line

A list of training tasks for practicing the skills of applying a welding seam on workpieces located in different planes

• Task No. 1. Welding in the lower butt position
• Task No.2. Welding in the lower corner position
• Task number 3. Welding in the vertical butt position
• Task number 4. Welding in the ceiling angular position
• Task number 5. Welding of butt joints on a plate in a vertical angular position
