This is Alex. We have been working all week long on perfecting the house and ice core missions. David tried to create an arm and program that can grab the drilling rig. We did not have much success with that. The house has been getting better, then messing up, then getting better again. It's irritating. Right now, we are re-fixing it. We have had a little more luck with the ice core mission. We can consistently gather the items and deliver them to the house. We can almost always open the window, and the ice core is about 50-50. We need David's help to work on the ice core mission, and he's in Dallas for Spring Break. So, we're just working on the house mission.
On the bright side, we have gotten the levees mission working every time, and since the final mission is just point-and-shoot, we don't have to worry about that one. Now, I have to get to work.
About the two frames we made: Nic and Cheyne's does work better, but we have decided against using it to align the robot because, when it turns, the frame catches on the wall and makes it inaccurate. However, we are still using the frame because it makes the robot more secure.
