Description

Base class definition for a Curiosity driver.

A derived class must implement the Update function to set the various motor controls at the current time. Alternatively, a derived class may directly access the associate Curiosity rover and control it through different means (such as applying torques to the wheel driveshafts).

Member Function Documentation

◆ SetSteering() [1/2]

void chrono::curiosity::CuriosityDriver::SetSteering ( double angle )

Set current steering input (angle: negative for left turn, positive for right turn).

This function sets the same steering angle for all steerable wheels.

◆ SetSteering() [2/2]

void chrono::curiosity::CuriosityDriver::SetSteering	(	double	angle,
		CuriosityWheelID	id
	)

Set current steering input (angle: negative for left turn, positive for right turn).

This function sets the steering angle for the specified wheel.

◆ Update()

virtual void chrono::curiosity::CuriosityDriver::Update ( double time )

protectedpure virtual

Set the current rover driver inputs.

This function is called by the associated Curiosity at each rover Update. A derived class must update the values for the angular speeds for the drive motors, as well as the angles for the steering motors and the lift motors at the specified time. A positive steering input corresponds to a left turn and a negative value to a right turn.
