2014-05-15 05:03:49 -0500 | commented answer | move_base and extrapolation errors into the future Thanks for the opened ticket. So the next step is to amend the code in goal_functions.cpp I've downloaded the move_base source code from github and have confirmed that the absence of waitForTransform. Would I be able to compile only base_local_planner or would I need to recompile all of move_base? |

2014-05-14 13:42:07 -0500 | asked a question | move_base and extrapolation errors into the future I'm trying to launch the navigation stack in a PatrolBot from an external computer. From the internal computer, I have I've been able to create a map with the instructions published in the MappingFromLoggedData tutorial. I've created the Running I run the navigation stack, and with Everything is well up until this point. However, when I propose a Navigation goal through
I've narrowed down the error to the After a couple of days of searching for a solution it appears as though a I'd attach my yaml and launch files, to see if I've missed something, but I don't have the karma points for it. I can copy and paste them in the comments below if need be. Thanks. EDIT 2014-05-22: I have downloaded the move_base git, and compiled the base_local_planner agent (which requires to gitclone cmake_modules from github as well, by the way). I've added the following in line 110 in goal_functions.cpp (right before the lookuptransform call) and compiled:
The error of future extrapolation has disappeared, however the base is still not moving. The following warning is now repeatedly shown:

2014-05-13 05:44:04 -0500 | asked a question | Has anybody tried to use the PatrolBot's joystick with ROS' joy? The tutorials mention that "joy" requires the joystick be accessed from a /dev/input/jsX file, however the joystick that comes included with a PatrolBot (the big, blocky, yellow device with a joystick, a knob and a "go" button) is not, as far as I know, set as dev/input device (frankly, I'm not even sure it's able to be accessed from the onboard computer as a device, anybody know?). I just wanted to know if anybody out there has tried using the joystick within ROS via the "joy" node or something similar. |
