chrono::ros::ChROSBodyHandler Class Reference

Description

This handler is responsible for publishing state information about a ChBody.

This handler creates three publishers for the pose, twist (linear/angular velocity), and accel (linear/angular acceleration) topics.

Constructor & Destructor Documentation

ChROSBodyHandler()

chrono::ros::ChROSBodyHandler::ChROSBodyHandler	(	double	update_rate,
		std::shared_ptr< ChBody >	body,
		const std::string &	topic = "~/"
	)

Constructor.

The based topic is concatenated before the individual topic names. This handler will publish to the topics: <topic>/pose <topic>/twist <topic>/accel where <topic> is the passed in topic argument. If the no topic is passed, the topics will be: ~/pose ~/twist ~/accel
