Hudson, the butler bot.

I got the Drive motors and wheels mounted last night, the battery controller circuit and motor controller all mounted, and all the wires have been put through. As a test I used the 5v regulated power and the Signal and power leads for the motor controller to hook it up to an RC reciever, so I could hook it all up and test the drive system. The videos I have attached show off the drive system, going over Large Tile, Medium tile and carpet... I had to help the transition for carpet a little bit, it high centered while moving over. I probably need to drop down the casters just a little more.
Let me know what you think!

I have added on the Distance sensors on front, also reconfigured the Arm a bit. I then have spent the last few days soldering together a breaker box, essentially that connects both batteries together and outputs all the votages I need. I have the 11.1v LiPo going in one side, and the 7.4v liPo going in the other, outputs vary, a kinect power adapter output, 1 11.1v output for the motor controller, a 7.4v output for the Servos, and a 5v output for the Logic for the Servo Controller. Oh and I added Tension springs to the arm so my servos don't die lol. Now all I need to do is get the drive system in place, which I found out I don't have the apropriate hubs for the wheels :\ so i will have to to wait to get those in before it is moving... I have though about jerry rigging the the hubs to work.. or gettings the bigger wheels that I do have hubs for but I haven't decided which yet.

Due to over heating computer issues, this is now the third time I will be attempting to write this :\
Hudson, is a butler robot, I'm designing him to initially grab snacks and be asked to go get various items.

Here is his Specs:
Hardware-
-Arduino microcontroller serial connected to a Lynxmotion SSC32 servo controller
-A robotic arm, brackets and base are all parts from Lynxmotion, servos are kind of a hodge podge of different types.
-2 IR sensors, both for wall and stair sensing(so he doesn't take a fumble :P )
-A ultrasonic range sensor for long distance sensing.
-Microsoft Kinect, for 3d vision sensing
-Motors for the drive system are, 12v Geared motors, stall torque is 231.5 oz-in, 152 rpm
-The Brains, HP Mini 1000 netbook, running Ubuntu and ROS from Willow Garage

So yeah my robot so far. Let me know what you think. I'm open to suggestions.

Thanks for viewing.
