CONSTRUCTION EQUIPMENT VIRTUAL TRAINER
The Construction Equipment Virtual Trainer (CEVT) is to both train Soldiers upon initial entry and transition from the classroom to actual equipment by proving a null risk training environment. CEVT shall provide realistic and challenging training using simulated terrain and movement characteristics that enable the student to transfer motor-skills from simulator to construction equipment.
The Construction Equipment Virtual Trainer (CEVT) is to both train Soldiers upon initial entry and transition from the classroom to actual equipment by proving a null risk training environment. CEVT shall provide realistic and challenging training using simulated terrain and movement characteristics that enable the student to transfer motor-skills from simulator to construction equipment. CEVT allows Soldiers to perform construction tasks that vary from leveling earth to excavating a trench and from constructing a stockpile to loading a hauling unit.
This allows the instructor operator and the trainee to physically see and interact heightened and lowered terrain using vehicles such as the grader, scraper, and dozer.
With the use of a 3DoF motion platform. The motion platform can pitch forward and backward, roll/tilt to the left and right, and heave up and down and can vibrate to simulate the response of no-load engine idle conditions.
Scenarios specify the vehicle, the terrain, the steps the student must perform, the prompts that should be displayed, and the scoring scheme that should be used in the grading score.
Reconfigurability gives the instructor the option to remove the entire vehicle cab and all of its controls and reinstall another vehicle cab containing entirely different controls.
These software components have similar inputs and outputs as their real-world counterparts in order to simulate a particular machine’s behavior as accurately as possible.
By providing a way to remove the entire vehicle cab and all its controls from the motion base and reinstall another vehicle cab containing entirely different controls the instructor and student can experience multiple platforms very quickly. This process allows two people to reconfigure the simulator from one vehicle variant to another in less than 5 minutes, vastly outperforming the CEVT reconfiguration requirement of 60 minutes or less.
Using AVT's dynamic terrain software, the student and the instructor are able to use the vehicles e.g. the Dozer and while operating they are able to see not only the contents which they are pushing but also the vehicle tracks, different grades of the soil, compacted terrain, and uncompacted terrain. When doing leveling operations (grading) any excess material in the blade will move along the blade and create a windrow to the side of the blade as one would expect.
The motion platform receives inputs from the variant's physics model to give feedback to the operator. In this manner, the platform will roll, pitch, and heave appropriately depending on the movements on the simulated vehicle. When the simulated vehicle interacts with objects in the terrain the effects of these interactions are mapped to movements on the platform (e.g. pushing the bucket of an excavator into the ground, will lift the tracks off the ground and the motion platform will pitch/roll accordingly).
“We are thrilled to have the opportunity to provide Army Engineers with a training solution that will increase their readiness. We look forward to working with our extremely competent and proven teammate, 5DT, to deliver this capability to the Soldier. As they say at Ft. Leonard Wood – Essayons!”
