Building an autonomous robot from an Xbox 360 controller  Wow,
it’s amazing what [Carl] was able to build using an Xbox 360
control PCB as the base for his robot. His forum posts just
touches the surface of the build, but he linked to a PDF file
which has the full details.  This build basically attaches
sensors and replacement motors to the controller board… and that
is it! Some distance sensors are connected to the analog inputs
for the left and right trigger. The whiskers use a couple of
leaf switches soldered to controller button pads. The motors are
geared replacements that use the same connectors as the rumble
motors did.  The idea is that the controller is connected to a
PC via the wireless radio it has on the PCB. Once the connection
is made the PC software can read from all of the sensors and
drive the motors accordingly. It would also be really easy to
use a single-board solution like the RPi to do away with the
need for a remote PC. But this is a fantastic start, and an
approach which we had never b
