We managed to write the HelloWorld code, implement a simple robot, and run a simple program on its motors to show that it works. In the way of doing this, we confronted two problems. First problem was that we were unable to communicate with the uorc board. The problem was with the board and was solved by short circuiting the Estop. The second problem was that the motors were connected so tight to the wooden board that they did not move. We solved the problem by loosing them. We're hungry!!!

We have discussed strategy, structural and mechanical design and are still discussing strategy!! Plus we are deciding who gets to keep their computer plugged in to the wall. Unfortunately, plugs only come in pairs. We have a really good schedule set up and are planning to follow it even if it mean building the robot in the next 5 days! However, we are quite pleased with our design and feel that any obstacles will only make us stronger!!

Today we completed checkpoint 3. We ate subway sandwiches. Two of us got trained at Edgerton. We chose the design for our robot. We failed at naming our robot. Voitek is trying to do all the coding tonight for both checkpoint 4 and 5. YES! The design of our robot consists of two Archimede's screws and a collection basket on the top level of our robot to throw balls over the opposing team's wall. Simple and effective Over and out.
Thursday January 6th, 2011
Completed two archimede's screws which are the direct opposite of each other. Preliminary ball elevating operations succeeded but we need to attach three shafts for it to work correctly. We completed two checkpoints in one day today as well (4 and 5).
Friday January 7th, 2011
Completed two shafts that will make the archimede's screws spin. Ordered gpu online. Began work on encoders.
Saturday January 8th 2011
Continued work on encoders.
Sunday January 9th 2011
Continued work on encoders. Cut wood for the screw casing which will be attached to the back of the robot. We plan to have an operational robot by tuesday.
To be continued :]
Tuesday January 11th
After some tinkering it seems that 1 screw will work much better than 2 screws, especially in terms of stability. So we reconfigured the designs.
Wednesday January 12th
Epically snowed out of the lab.
Friday January 14th 2011
Mock Contest today!! So we found out that our robot was slightly too close to the ground so we had to cut the guides on the bottom of the robot. So we took the robot apart after the mock to work on it. During the interview we put our robot together for a picture and it looked awesome!( with the exception of no orc board, computer or battery ) It looked as though our robot will be running by will power!! Front door was made and hopefully trap all the balls bwahahaha...
Saturday January 15th 2011
Took robot apart again :] this time to put on the new epic mice encoders. They are attached with a spring system making them versatile to the change in terrain. Now just gotta code them perfectly >.<
Sunday January 16th 2011
Wrote code for PID!!
Monday January 17th 2011
Measured camera angles and positions relative to our center for parameters of the vision program. Found an infinite loop in the vision program. Everything should be working better. Although mice are not being cooperative and only one work at a time.
Tuesday January 18th 2011
Found that mice input different data than what the program expected and that's why we couldn't find the mice input when we initiate the program! Calibrating our cameras by using a graphical ground to travel on.
Wednesday January 19th 2011
So the robot will be name HITMAN: AGENT 47 With some more coding we may be able to not only graphically show the audience the where the balls are but also a map of the maze that we have traversed so far. And keep calibrating the cameras!!
Friday January 21th 2011
Front gate is officially on!! And it works quite well?! Less than a dollar's worth of wire and cardboard with a bit of hot glue does the job! The mother board and orc are officially installed and ready to go!
Saturday January 22nd 2011
So we are getting new battery supply!! 2 sets of car batteries which will charge the motherboard and orc board! They even fit quite well too! And we still have to keep calibrating the cameras for the best results.
Monday January 24th 2011
The gear seem to have stopped staying attached to the screw. We can fix that! Also, we put sliders on the mice to prevent it from getting stuck and breaking. More camera calibration is in effect :]
