Tasks	Reflections
Prototyping the Goal Moving Device	Brad, Braden, Akhila, Morgan and Trevor worked on trying to design and build an effective way to pick up the goals and move them around. Trevor created two designs for potential rolling goal possessors. These included a very small linear slide and a small lever both controlled by servos. He also discussed another possible design for a potential rolling goal possessor. His new idea used a ramp and a platform to hold the rolling goals which would also include points for getting a rolling goal off of the ground. We figured out that the ramp would not work but that two pegs on the end of the robot ended up working well. We settled on trying to use two pegs to move around the goals.
Working on Linear Slide in SolidWorks	Justin, Josh and Andrew worked on getting custom parts for the linear slide so it can be moved more easily. Josh chose to sit at his computer waiting for Andrew the mentor to help him with Solidworks, which just may be the most complicated thing in the world!
Shooter Mechanism	Laura and Akhila worked on prototyping the ball shooter that they had been working on for the past few meetings. The design includes a wheel powered by a motor, which will work to shoot the ball through a tube. We started with making a frame to hold the wheel and motor, so it was more reliable, and safer, than just holding it in our hands. Then we cut a slit out of the PVC pipe that the wheel would fit in. Amal, Nick, and Laura also worked on the tube cutting to make the motor fit inside the tube. We accidentally put the wheel at the wrong height and had to redo a lot of work. We learned the important lesson of measuring before building. We finally got a chance to shoot the ball. It definitely seemed to be fast enough to make it into the tallest goal. It was really cool and exciting to watch!
