Viper rover class.

This class encapsulates the location and rotation information of all Viper parts wrt the chassis. This class should be the entry point to create a complete rover.

Member Function Documentation

◆ GetDriveMotor()

std::shared_ptr<ChLinkMotorRotation> chrono::viper::Viper::GetDriveMotor ( ViperWheelID  id) const

Get drive motor.

This will return an empty pointer if the associated driver uses torque control.

◆ GetDriveMotorFunc()

std::shared_ptr<ChFunctionSetpoint> chrono::viper::Viper::GetDriveMotorFunc ( ViperWheelID  id) const

Get drive motor function.

This will return an empty pointer if the associated driver uses torque control.

◆ Update()

void chrono::viper::Viper::Update ( )

Viper update function.

This function must be called before each integration step.
