      Brian...
Not to downplay the advantages of available Amateur Radio Satellites in your
decision making process but...
Another opportunity to consider is to "piggyback" on someone else's
"non-Amateur Radio" experiment. There are several "experimental" satellites
that currently are controlled by universities and the like. You might be
able to work with them to transmit your test code and have your robot react.
Also you must learn the difference between geo-synchronous(sp) and
polar-orbiting satellites. Current availability of "experimental satellites"
are in the polar orbiting category which might mean, without a significant
antenna, you may only get 10 minutes 2 times a day to attempt your project.
Of course if you can con someone at SIRIUS or XM to open up a channel for
you or play your code, that's another thing. Commercial time on other
Geo-Sync's can be "purchased."
In the Amateur Radio venue, there are also several digital satellites that
exist that might relay your code however your control code would have to
work within the satellite's existing communications parameters.
Consider, as it is an experiment, using a balloon repeater for the initial
demonstration. With that success you can continue to pursue your satellite.

If you could expand on your request to "control a robot from a satellite"
with more specifics then you are likely to get better ideas and suggestions.
...
Some additional details like... Where would the command station and robot
be located? How much time would you need to command the robot each day? What
mode would the commands be sent in (digital, audio, FM, SSB...).
...
Hope your project goes well.

My goal is to be able to control a robot from a satellite, I'm with a
group

that is trying to compete in the lunar X prize, here's a video of our
earthbound test rover. Also what would be the best transmitter & receiver

buy for this goal?

Yes.  You need to have a amateur radio license for the bands you wish to
work, specifically the "uplinks".  For example if you wanted to work some
of
...
the LEO satellites like AO-51, SO-50, etc. you need at least a
"technician"
...
class license.  Take a look at ARRL's information as to what bands you can
operate with which license (see:
http://www.arrl.org/FandES/field/regulations/bands.html).
Information about the amateur satellites in operation can be found at
www.amsat.org.
Next question?  :-)

Hi,
This will be the first of probably 1000 questions. Do I need licenses to
work with amsat satellites?
Thanks, Brian
