I've attached some images of the rviz model. 

The first and second images show the robot from different angles. Both times, his feet are hidden by the far side of the stand he's attached to.  "Rviz Perspective2.png" also shows that from this angle his right arm is behind the stand which doesn't make sense.

I tried the command `sudo apt-get update && sudo apt-get dist-upgrade` to no avail.  The questionably faulty machine is currently running Rviz version 2.4.6

Thanks in advance
