Let's Make Robots!

People looking at you robot

I somehow dont know what to think when somebody looks at you robot, spots the arduino board, then askes if the computer board thingy came from an old computer. Anyone else have thoughts?

Tricopter yaw servo

What would be a fairly simple way to mount the yaw servo for a tricopter?

I was thinking of having the yaw servo connected via linkage to the arm which the motor is mounted on then having the arm out to the motor be mounted through 2 bearings supporting it while allowing the whole arm to tilt.

Is there any other ways that would work, preferably without any custom parts?
