rosrate

Execute loop at fixed frequency

expand all in page

Description

The rosrate object allows you to execute a loop at a fixed frequency. The rosrate object uses the global ROS node as a source for time information. Therefore, it can use the ROS simulation or wall clock time (see the IsSimulationTime property).

The performance of the rosrate object, and the ability to maintain the desiredRate value depend on the publishing of the clock information in ROS network. Because the rosrate object relies on the pause function, disabling pause will result in inaccurate execution.

If rosinit creates a ROS master in MATLAB®, the global node uses wall clock time.

Tip

The scheduling resolution of your operating system and the level of other system activity can affect rate execution accuracy. As a result, accurate rate timing is limited to 100 Hz for execution of MATLAB code. To improve performance and execution speeds, use code generation.

Creation

Syntax

rate = rosrate(desiredRate)
rate = ros.Rate(node,desiredRate)

Description

rate = rosrate(desiredRate) creates a Rate object, which enables you to execute a loop at a fixed frequency, DesiredRate. This syntax sets the DesiredRate and DesiredPeriod properties of the Rate object. The time source is linked to the time source of the global ROS node, which requires you to connect MATLAB to a ROS network using rosinit.

example

rate = ros.Rate(node,desiredRate) creates a Rate object that operates loops at a fixed rate based on the time source linked to the specified ROS node, node.

Properties

expand all

This property is read-only.

Indicator if simulation or wall clock time is used, returned as true or false. The value of this property is same as that of the use_sim_time parameter with these behaviors:

  • false — The Rate object uses wall clock time to regulate the rate of loop execution.

  • true — The Rate object uses ROS simulation time published on the /clock topic to regulate the rate of loop execution.

To set the use_sim_time parameter, follow these steps:

ptree = rosparam;
set(ptree,'/use_sim_time',true)

This property is read-only.

Desired execution rate of loop, specified as a scalar in hertz. When using waitfor, the loop operates every DesiredRate seconds, unless the loop takes longer. It then begins the next loop based on the specified OverRunAction.

This property is set during the object creation.

This property is read-only.

Desired time period between executions, specified as a scalar in seconds. This property is equal to the inverse of DesiredRate.

This property is set during the object creation.

This property is read-only.

Elapsed time since construction or reset, specified as a scalar in seconds.

This property is read-only.

Elapsed time between last two calls to waitfor, specified as a scalar. By default, LastPeriod is set to NaN until waitfor is called for the first time. After the first call, LastPeriod equals TotalElapsedTime.

Method for handling overruns, specified as one of these character vectors:

  • 'drop' — waits until the next time interval equal to a multiple of DesiredPeriod

  • 'slip' — immediately executes the loop again

Workflow of drop and slip overrun handling methods.

Each code section calls waitfor (Robotics System Toolbox) at the end of execution.

Object Functions

waitforPause code execution to achieve desired execution rate
statisticsStatistics of past execution periods
resetReset Rate object
