Standard construction dump truck in the Offroad Vehicle Library

expand all in page

Add-On Required: This feature requires the Robotics System Toolbox Offroad Autonomy Library add-on.

Standard construction dump truck with a rigid frame and front-wheel steering. The dump truck has six wheels on three axles: one front steering axle and two tandem rear axles. For bicycle kinematics, the effective rear axle is the midpoint of the tandem pair.

Description

The dump truck is a large, heavy vehicle with a wide turning radius, suited for hauling material along structured routes on construction sites.

Load it programmatically with loadvehicle("dumptruck") or add it to a Simulink® model with the Simulation 3D Physics Dump Truck block to simulate in an Unreal Engine® scene.

Dimensions

These illustrations provide insight into the dimensions and locations of the DumpTruck asset parameters relative to the coordinate axes, following the yaw(z), pitch(y), roll(x) sequence. The vehicle layout follows Unreal Engine co-ordinate system which follows the left-hand rule world coordinate system. For more information, see Coordinate Systems for Unreal Engine Simulation in Robotics System Toolbox.

Dump truck axle positions

The vehicleData structure returned by loadvehicle includes a RearAxleWheelBase field representing the distance from the front axle to the second (rearmost) rear axle. The WheelBase field represents the distance from the front axle to the midpoint of the two rear axles, which is the effective rear axle position used for bicycle kinematics.

The rigidBodyTree model includes measurement frames such as front_axle_center, rear_axle_center, and rear_axle_rearmost. Use getTransform to obtain axle positions and distances programmatically.

The dump truck model is designed for kinematic workflows and does not include body inertia data.
