United Tractors School / 2019
Practise excavator procedures before using the machine
A deployed PC VR trainer with driving and maintenance modes. The air-filter service shows how a real procedure becomes a sequence of hands-on actions.
Muhammad Faisal designed and built this project while at a prior employer, which held the client contract. His role covered design, development, optimization and deployment. Simvra has permission to show the work.
The task
Make a maintenance sequence repeatable
New operators and maintenance technicians need hands-on practice. On real equipment, that practice uses machine time and gives a class limited access to a single engine bay.
The trainer recreates the excavator and engine bay using the real machine's geometry. The challenge is more than showing the parts: the trainee needs to handle tools and complete the service in the right order.

Driving and maintenance modes, with the maintenance procedure shown in this case. This historical build used tethered PC VR headsets and a workstation.
Implemented behaviour
The next step waits for the right action
Open the housing, clean the cover, dust the filter element and mark the maintenance number before closing up. VR hand-controller actions advance the procedure in order.
Delivered application
The trainer was delivered to United Tractors School in 2019. The footage shows its guided air-filter maintenance procedure.
Technical scope and constraints
The project ran in Unreal Engine on a single PC VR trainee station. It combined a full excavator scene with an interactive engine bay and ordered maintenance actions. The six-month engagement included optimization and deployment.
What we'd define before building something similar
We'd define the procedure, required actions, target device and review criteria with you. Your subject-matter expert checks the content and sequence, and we check the build on the hardware specified in your contract before acceptance.
Start with one equipment procedure
Tell me about the machine and procedure. We can start with one maintenance task, inspection or operator sequence as a first module.
