1:30PM - 5:00PM
1) worked on motor controller board (1h)
2) got and setup wireless router (2.5h)
-------------------------------------------------------------------------
1) Continued to look for and draw up components for the motor controller board
2) Went to the Cornell store to buy a wireless router and then set it up in prof. ruina's office.

1) Discussed motor controller board with Jason.
----------------------------------------------------------------
1)Discussed what we have to put on the motor controller board and various other things relating to said board, such as how it was going to fit in the small boxes.

1. Finished LabView interface fix (1.5 hr)
2. Helped Bram with robot calibration, cable stiffener and ankle encoder (1.5 hr)
---------------------------------------------------------
1. The interface now has a legend for the data channels, making it easier to select graphing data. The graphs also display the name of the data being graphed
2. One of the ankle encoders came lose, so I fixed it. I also helped Bram put a piece of rod on the cable of the left outer leg to increase its stiffness

1. Helped Jason collecting data from Ranger (walking trial) (30 min)
2. Started updating Labview interface program for ease of usability (1 hr)
3. Lab Meeting (2 hr)
--------------------------------------------------------------------------------
1. Jason wanted to try to get Ranger walking a few steps. Using the old controller, it kept stumbling so we decided to graph some data to troubleshoot it. We have not found the problem
2. I was asked to make the LabView interface program a little less confusing for graphing data. I started looking at the program to understand it, and began trying out some ideas.
3. The amazing presentation by Prof. Ruina was a little longer than I expected, but I learned a lot about our lab I did not know before. It felt good to be approached by other interested students and be able to answer questions confidently.

1. Installed vent cover I manufactured yesterday (40 min)
2. Discussed with Jason on battery box mounting, came up with a plan (1 hr)
3. Looked on Digi-key for connectors to use on battery cables (1hr)
----------------------------------------------------------------------------
1. I used wood screws to mount the piece of plywood to the frame of the vent. It is sturdy and seems to provide a good seal
2. After finding out we don't have enough space inside the main boxes to attach the battery plug, Jason decided we will instead rout cables from each of the outside boxes to the top frame of the robot, while the inside box will become snap-on. I have come up with several mounting ideas, and Jason decided on the particular box he wants to use for the batteries
3. Because each of the outside batteries only requires 2 cables, I was given the task of looking for panel-mount 1-circuit connectors. I have had no success with digi-key, so Jason decided using the 3-circuit connectors will be easier.

Hours : 11 am to 2 pm
1. Resolved installation issues with package used (30-45 mins)
2. Testing sample files with SciPy and PyDSTool (2 hours)
--------------------------------------------------------
1. Resolved some installation issues with PyDSTool and its dependencies which had been bugging me for the past week.
2. Successfully ran a few sample animations (.py files) purely using SciPy (an open-source package in Python for scientific computing which supplements and depends on NumPy, another package in python that is good for fast manipulation of large arrays) - I picked up these programs (simple pendulum and the simplest walker) from :
http://pages.physics.cornell.edu/~myers/teaching/ComputationalMethods/
Also testing PyDSTool, running the test files that came with the installation package and so on. It might be possible to build a model using simply SciPy and NumPy, and we might not need PyDSTool. Will look in the coming days.

1. Constructed cover for wall vent (1.5hr)
2. Shopped around for new battery boxes (1.5hr)
------------------------------------------------------
1. I made a plywood and foam cover for the vent on the wall above the windows, so the lab stops leaking heat. Beforehand I had attempted to construct it all out of insulation foam but found out we do not have enough for the whole window
2. Jason explained to me the requirements for the new battery cases and I have been shopping online at McMaster, Digi-Key, and finally RadioShack to find suitable boxes. I have finally found 3 models that could fit the robot
