2019-09-20 02:19:04 -0500	marked best answer	Can a sequence of nodes be run in SMACH, behavior trees, or similar? Hi, I am looking for a solution to the idea of creating a state machine as a sequence of nodes, or a sequence of concurrent nodes. Where the nodes, could be nodes of any type that a user has created. SMACH/pi-trees/flexbe, out-of-the box seems to work with actionlib, services, topic monitoring. But what if you want to take an FSM and do as follows: `state1 (node1) -> state 2(node 2) -> state3(node3)`, while checking some kind of transition checking. Or perhaps running nodes concurrently: `state1 (node1,node2) -> state 2(node3, node4) -> state3(node5)`, this would also be similar to having each state call a launch file.... Thanks

2019-04-10 21:37:32 -0500	marked best answer	Use wstool but keep git directories organized under a custom structure Imagine I have the following structure in my directory: `ros_ws \|__src \|.rosinstall \|__robots \|__baxter \|__baxter.rosinstall \|__baxter_sdk \|__.git ... \|__sawyer \|__sawyer.rosinstall \|__sawyer_sdk \|__.git` Is there a way to call wstool update locally or globally to update git repos but keep them in my pre-established structure. Currently when I do wstool update it want to place updated git repo folders directly under ros_ws/src.

2018-07-09 13:57:00 -0500	marked best answer	Can't get dynamic reconfigure to spin when callback is a member of a class I am using ROS Indigo, Ubuntu 14.04. Get no compile errors. When I debug with GDB I can see I go into my callback once, but no more thereafter. This also happened when the callback was made global outside the class. I thought that perhaps this was why it was not being called. But it seems this is not the problem. I have three other subscription callbacks in this code that work fine as well one publication. Below I show the callback and the main function. Currently I use spinOnce() but I have tried other spin mechanisms like spin() AsyncSpinner, MultiThreadedSpinner to see if that made a difference. The full file / ROS package can be found here: https://github.com/birlrobotics/birl_... Any help would be greatly appreciated. namespace force_controller { //********************************************************************************************************************************************* // callback(...) for dynamic Reconfigure set as a global function. // When the rqt_reconfigure gui is used and those parameters are changed, the config.param_name in this function will be updated. Then, these parameters need to be set to the private members of your code to record those changes. //******************************************************************************************************************************************* //void callback(force_error_constants::force_error_constantsConfig &config, uint32_t level) void controller::callback(force_error_constants::force_error_constantsConfig &config, uint32_t level) { // Print the updated values ROS_INFO("Dynamic Reconfigure Prop gains: %f %f %f %f %f %f\nDerivative gains: %f", // Proportional Gains config.k_fp0, config.k_fp1, config.k_fp2, config.k_mp0, config.k_mp1, config.k_mp2, // Derivative Gains config.k_fv0); // Save proportional gains to the corresponding data members. k_fp0=config.k_fp0; k_fp1=config.k_fp1; k_fp2=config.k_fp2; k_mp0=config.k_mp0; k_mp1=config.k_mp1; k_mp2=config.k_mp2; // Save derivative gains to the corresponding data members. k_fv0=config.k_fv0; // change the flag force_error_constantsFlag = true; } ... ---------------- int main(int argc, char argv) { ros::init(argc, argv, "control_basis_controller"); // Create a node namespace.

2018-02-28 20:41:49 -0500	marked best answer	Problems with .rosinstall when calling wstool merge Using Linux 14.04, ROS Indigo. I am familiar with wstool. Just expanded my repository to better organize code: https://www.github.com/birlrobotics Trying to do the traditional steps: wstool init wstool merge [address] wstool update Now, when I try westool merge with the following file: wstool merge https://github.com/birlrobotics/birl_... I get the following error: `ERROR in config: Invalid multiproject yaml format in in "<file>", line 7, column 19` A few points here: It does not seem that the line 7, column 19 points to anything I can figure out. I have tried going over this file multiple times trying to figure out if there are any small mistakes and I can't find anything. If I just copy the contents of the file into a local birl_baxter.rosinstall file and then call `wstool update` IT WORKS. The output below is obtained with `wstool info` if I copy the contents manually: workspace: /media/vmrguser/sdd/ros/indigo/birl_baxter_ws/src Localname S SCM Version (Spec) UID (Spec) URI (Spec) [http(s)://...] --------- - --- -------------- ----------- --------------------------- birl_baxter_wiki git master bba17767ba05 github.com/birlrobotics/birl_baxter.wiki.git birl_sensors git master 68002e8ab082 github.com/birlrobotics/birl_sensors.git birl_baxter_worlds git master 89a310a39f9e github.com/birlrobotics/birl_baxter_worlds.git birl_baxter_vision git master ac6b6776b216 github.com/birlrobotics/birl_baxter_vision.git birl_baxter_tools git master c96785268756 github.com/birlrobotics/birl_baxter_tools.git birl_baxter_recorded_motions git master ed05ddf0e0af github.com/birlrobotics/birl_baxter_recorded_motions.git birl_baxter_msgs git master 3fb7faa7bb38 github.com/birlrobotics/birl_baxter_msgs.git birl_baxter_matlab git master 9cf0165b4f8c github.com/birlrobotics/birl_baxter_matlab.git birl_baxter_images git master 383a8c428bdf github.com/birlrobotics/birl_baxter_images.git birl_baxter_hands git master 6d88ca03a51b github.com/birlrobotics/birl_baxter_hands.git birl_baxter_executive git master 839f854ab3a2 github.com/birlrobotics/birl_baxter_executive.git birl_baxter_examples git master b99fb7e3bc37 github.com/birlrobotics/birl_baxter_examples.git birl_baxter_demos git master 84f109b8f308 github.com/birlrobotics/birl_baxter_demos.git birl_baxter_controllers git master a5914da2a7ec github.com/birlrobotics/birl_baxter_controllers.git birl_baxter_common git master 769c4676a999 github.com/birlrobotics/birl_baxter_common.git birl_baxter git master 45717b2422fd github.com/birlrobotics/birl_baxter.git Does anyone have an insight into this?

2017-09-17 13:20:55 -0500	marked best answer	How to launch stereo view from inside a launch file I am having trouble with thinking how to do two arguments inside the args type of a node element in the launch file. Consider wanting to launch the following node inside a launch file: `rosrun image_view stereo_view stereo:=/my_stereo_cam image:=image_rect_color` We would have something like this: `<launch> <arg name="stereo" default="multisense_sl/camera"/> <arg name="image_view" default="image_rect_color"/> <node name="stereo_cam" pkg="image_view" type="stereo_view" args="stereo:=$(arg stereo) image:=$(arg image_view)" > </node> </launch>` I have tried different combinations of arguments formats, quotes, and just can't get it to work. I would appreciate any advice. Thanks
