2014-03-09 06:03:46 -0500 | asked a question | what is the purpose of zeroconf and avahi? Recently, I discovered a process on my ubuntu that was eating away at both processor time and memory, 18% and 10% respectively. What purpose does zeroconf and avahi serve when the amount of resources it consumes is detrimental in a resource scarce scenario such as most robot systems, e.g. 7-DOF manipulators, vision-based path planning/navigation, etc? I am trying to understand what, why, and how of this package/stack. I feel like it should be deprecated. |

2012-07-09 03:34:24 -0500 | asked a question | ROS Stage in Fuerte on 12.04: Stage controller tutorial only for 3.x.x Is there a way to get the controller tutorial working for ROS Stage 4.x.x? I ran into the following problems when attempting to get the tutorial working though it is not meant for my version of Stage. Link to tutorial here First Error: Fix: roomba-wander.world: ln35 col18: laser to ranger Second Error: I don't know how to fix the second error. Any information would help. |

2012-07-09 02:03:27 -0500 | asked a question | ROS Stage in Fuerte on 12.04 only supports 1 ranger or 1 sonar type how to do both I understand that there is a ROS stage limitation of support where a robot is only allowed to have "rangers with 1 sensor only." As referenced here. As well as a rename of the Laser to rangers type, as referenced here. Then how do I create a robot model to the specifications of my physical robot which will be compatible with ROS Stage 4.1.1? See here for breakdown of S1R. I have a mix of sonar, IR, and laser rangefinder. Currently, I would have to strip it down and only have one sensor on it, and I certainly don't want to do that. What happened to the change in Stage that allowed multiple sensors as described in here? The following world code is what I am working with: (more) |
