30 and 40 minute robot

I'm posting two stages at once because the photo upload tool on blogger was broken the other day. Anyway, here is the progress on the '10 minute robot'.

He now has a bracket mount for the tilt servo. I actually wasted 30 minutes trying to make this out of steel before realising that my lab's workshop hand-drill wasn't up to it. After giving up on that bit it only took 10 minutes to make this aluminium bracket out of scrap.

And here's a pan servo. Both degrees of freedom have been aligned with the sensor's center of rotation. Of course, mechanical offsets can be dealt with mathematically via trigonometry, but right now I wanted to solve this problem mechanically rather than in code.
