• Akhila, Laura, CJ, Nick, and Amal tried to prototype and test out a shooter mechanism using a wheel. The first time the mechanism was tested, the wheels were damaged in the process. They are now trying to figure out a more efficient way to design and execute the mechanism, using the same original concept.
• The wheel collapsed one time and the screws came out and one screw was lost and could not be found.
• We went to the FTC Workshop to help out on the parts of the robot.
• CJ burned a screw to make it come out of an object!.

• Brad, Morgan, and Braden worked on designing the 8-bar on Solidworks, and learned how to mate parts on the program. Sadly, the data was lost, but they now have the knowledge to recreate the design.

• Josh has a headache life after finishing all his solidworks designing the linear slide prototype, sliders, and sliders on the linear slide prototype.

• Nick, Laura, CJ, Akhila, and Amal worked on Prototyping single spinning wheels to send the balls collected into the desired goals. There were a variety of wheels tested this includes the standard Textrix wheel, Omni wheel, as well the orange grippy wheel. The first wheel that was tested was the regular textrix wheel. The outside rubber covering acted like rubber band and would actually separate itself from the plastic center when spun fast. This design was rejected due to this flaw. The next test consisted of an Omni wheel being spun using the standard textrix motor without a gearbox. The sides of the Omni wheel would separate when it spun fast. As a result of this the smaller side wheels on the Omni would fly off. This caused them to ricochet around the room and injured Nick's finger. This flaw also prevented this design from moving any further. Lastly a orange wheel was going to be tested. Considering the inside of the orange wheel did not fit with the axel of the tetrix motor, a change needed to be made to the design of it's attachment. This process was worked on until the end of the meeting and will continue the next meeting.

• CJ, Amal and Akhila also looked at other back up ideas for the robot. Mentor Clem gave the idea of a pulley device that served as a scoring mechnanism that instead of shooting the balls which was our initial idea we would drop the balls into the tubes for scoring.
