After multiple sessions designing the launcher, Johnny, Daniel, and Marco have finally created one of the major components of the first vex robot. After visiting their first robotics competition in Flushing Queens, new design concepts along with some minor constraints were obtained. The wheels driving the system have to have at least four wheels on each side in order to make official contact with the ball. Being that the ball is about 3-4 inches in diameter, the wheels are positioned perpendicular to the platform on each side; allowing the ball to make 45% more contact than conventional methods. In terms of other methods, Daniel has taken his own initiative and developed a crossbow-like launching system. Though it is a prototype for the final robot, it is deemed quite innovative according to his other teammates.
07/05/2018 Zachary managed to finish redesigning the extending claw. While the overall mechanism is now smaller than the original, it still has some of the same issues; the claw itself is too bulky and two motors may be needed to raise or lower the arm. After building the prototype for the launcher Deepa started working on the launcher by attaching it to the base. the base that I built using mecannum wheel and four motors for each and to increase the speed of the motors I used the chains and sprockets. 07/09/2018 Zachary is working on a prototype for the arm's turntable and lifting mechanism. Depending on the length of the lifting mechanism, he should be able to mount the arm on or near a corner of the robot. This should help resolve any mobility and dimension issues presented by the original approach, as well as make loading the launching mechanism easier. The lifting mechanism's concept can be described as "a glorified lever." The extending claw will be ra...
