 After that, the device should be paired to the laptop. And if you press the "Playstation" button (in the center), it should connect to the laptop. It vibrates a little to confirm.
+To get sixad to start all the time, do:
+  cd /etc/rc2.d && sudo ln -s ../init.d/sixad S99sixad
+==== guvcview ====
+guvcview and other uvc related things were not working with a recent kernel (4.4.x)
+The following fixes the problem:
+  sudo add-apt-repository ppa:pj-assis/ppa
+  sudo apt-get update
+  sudo apt-get install guvcview
+==== libuvc-camera for the webcams ====
+Create the file /etc/udev/rules.d/99-uvc.rules with the following inside:
+  # UVC camera Microsoft LifeCam Studio
+  SUBSYSTEMS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="045e", ATTRS{idProduct}=="0772", MODE="0666"
+(adjust for your webcam looking at lsusb)
+Then restart udev:
+  /etc/init.d/udev restart
+And re-connect the webcam. It should now be readable for everyone.
+Install the camera driver:
+  sudo apt install ros-indigo-libuvc-camera
+Create a launch file with the following contents:
+  <launch>
+    <group ns="camera">
+      <node pkg="libuvc_camera" type="camera_node" name="mycam">
+        <!-- Parameters used to find the camera -->
+        <param name="vendor" value="0x045e"/>
+        <param name="product" value="0x0772"/>
+        <param name="serial" value=""/>

+==== Configuring network to communicate with laser ====
+Connect the laser and make sure it is powered up with the battery.
+Go to the network connections icon (which is next to your volume icon in the Ubuntu GUI).
+There should be an ethernet connection existing which is not completely configured.
+On the bottom of network connections menu click on "Edit Connections...".
+Choose "Wired Connection 1" and click on "Edit...".
+There, in the "Ethernet" tab use Device Mac Address from the drop-down menu.
+In the "IPv4 Settings" tab choose "Method" "Manual" and in "Addresses" add a new address -- click on "Add". The "Address" is the IP address of the network card -- your ethernet to USB dongle, e.g. "192.168.200.1". As netmask use "255.255.255.0" and leave "Gateway" empty or zeros.
+In "IPv6" settings choose "Method" "Ignore".
+Done. It should connect automatically anytime when the laser is connected.
+==== Documentation ====
+One of our students was working on creating a map of the hallway using the little robots. Here's a PDF with some documentation of the mapping process and also the robot itself.
