2020-03-11 15:46:13 -0500 marked best answer robot reverses into final pose

I have a differential drive base, running TEB as the local planner under Kinetic. When I navigate to a destination, if the requested pose is not the same as the pose the robot took to get there, it always turns before the final position and reverses into the destination. This seems odd. I would have expected the robot to navigate to the destination, then turn on the spot to get the requested pose. I have checked to ensure I do not have any car-like settings, and I have set the min_turning_radius to 0.0. I am using a footprint model for the robot rather than the radius parameter. I changed it back to Point and radius but get the same results.

Does anyone have some advice on this, or will I need to delve into the C++ files and modify them?

2019-05-29 05:50:08 -0500 marked best answer Kinect 360 not working in Ubuntu 16.04

I am using Kinetic in Ubuntu 16.04. I have a kinect xbox 360 and the appropriate power supply. The kinect works fine in windows 10. In Ubuntu, it will not show up in lsusb. I can see the motor, but the rest of the components do not show. The best I can see is that it is being detected as a usb hub. But at each lsusb it changes IDs. Here is a sample from lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:07dc Intel Corp. Bus 001 Device 007: ID 04f9:0331 Brother Industries, Ltd Bus 001 Device 006: ID 0922:0020 Dymo-CoStar Corp. LabelWriter 450 Bus 001 Device 009: ID 15d9:0a33 Trust International B.V.

Xbox NUI Motor Bus 001 Device 098: ID 0409:005a NEC Corp. HighSpeed Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

running lsusb again gives: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:07dc Intel Corp. Bus 001 Device 056: ID 04f9:0331 Brother Industries, Ltd Bus 001 Device 055: ID 0922:0020 Dymo-CoStar Corp. LabelWriter 450 Bus 001 Device 059: ID 15d9:0a33 Trust International B.V.

It looks like it is being detected as an NEC hub, but after many days of this I am not sure of anything.

Has this been encountered before? What can I do next?

Thanks, Dave

Looks like the problem is in the install of opencv2. All are related to these dependencies. I'll try a clean install and build with cv_bridge. Thanks.

I have been trying to compile the face recognition package under Indigo, it generates 100s of errors which I am struggling to sort out. I wondered if someone else might have already solved this issue.

2013-11-20 13:18:00 -0500 answered a question What are the current challenges in Mobile robotics?

The same challenges that have always existed in robotics.

general perception, dealing with unexpected circumstances, understanding requests from people in normal acoustic situations, recognising people in all lighting or angles, manipulating small objects, objects never encountered before, handling soft items like a cable harness. The use of human tools.

the list is very long.
