The answer to the orignal query depends on the following:
whether or or not there is a deadline to meet and whether
or not there is some level of robustness/accuracy required.
If the answer to both questions is no, then the idead previously
suggested will be fine, and you may learn something from your
failures.
However, if this is a "real" robot, you can not afford the
engineering time required to set up such a device. Furthermore,
the acuracy and usability will be questionable. If your need
for angle sensing is low bandwidth, say < 1 Hz, a standard
clinometer from Sperry or Schavitz is probably the answer. If
you need high precision/high bandwidth, the answer would be a
IRS (Inertial Reference System). Several companies produce
these, but they are outrageously expensive.
