2015-12-23 17:27:21 -0500 asked a question Solution to "nan value in transform" error

I am trying to simulate a Baxter bot in Gazebo2- Indigo. I am getting the following error and need help debugging it. Here is the first message that I am getting:

INFO] [WallTime: 1450912978.152709] [0.000000] Controller Spawner: Waiting for service controller_manager/load_controller

Then the following two errors are continuously sent to the terminal.

2015-12-17 14:01:40 -0500 commented question I need a working Baxter URDF with Electric Grippers.

I need the URDF for my Gazebo simulation. I have the environment configured but I don't have the URDF file with the grippers attached. I have an experimental file but when I try to control the grippers with the keyboard controller, I get a message that says it "cannot be used with custom grippers."

2015-12-17 13:04:02 -0500 asked a question I need a working Baxter URDF with Electric Grippers.

I need a Baxter URDF with parallel electric grippers. Does anyone have one that works and can be controlled with the keyboard gripper controller?

Thanks that worked! Just for clarification, I went into my URDF file and adjusted all the joint names that started with: "right_..." or "left_..." to "r_..." and "l_..." respectively. Thanks for your help.

2015-11-26 01:29:57 -0500 asked a question Help Building Custom BAXTER grippers

I need help figuring out these two errors. They are both related, so solving one should solve the other. I'm building custom grippers for Baxter in Ros-Indigo (ubuntu 1404.2). I've built a custom URDF file along with a custom launch file. This error is the last error I have to figure out.

2015-11-25 11:57:38 -0500 asked a question How to run baxter gripper_keyboard.py with custom electric grippers

I'm trying to run gripper_keyboard.py with my custom Baxter URDF that includes the electric grippers. But i keep getting an error message saying that "custom grippers cannot be used".

Has anyone encountered this before?

Thanks

2015-11-24 13:24:25 -0500 answered a question Setting up Catkin Baxter Environment Error - INDIGO

SOLVED: opencv3 was not installed through apt. I did install it from source though. After deleting/uninstalling all versions of opencv, I went to the following link and installed it from there:

http://www.samontab.com/web/2014/06/i...

FOLLOW ALL STEPS - Including system restart.

Then i went back into the base of my workspace (baxter_ws) and ran catkin_make then i ran catkin_make install. After launch gazebo, baxter was inside and all the error messages were cleared.

I'm trying to setup a workspace to simulate Baxter in gazebo with Ros Indigo. When I run catkin_make in my workspace i get the following error:
