CSUN Matabots: VEX Robotics
By Joseph Palezyan
Below is the CAD of our VEX turning point robot, for the CSUN 2 Matabots team. The small bot frame had to be assembled C-channel by C-channel, mate by mate, for a steady foundation, from the start. Having the entire bot designs on Solidworks, before our competition is vital in gaining an advantage, with the ability to study/test different aspects of the bot, without dismantling it.

Above is the physical bot. I took pictures of the bot, as I began to reverse engineer each feature and dimension as they applied. This time, we decided to install an intake (spinning cylinder with orange rubber bands) towards the front of the robot. This robot also includes an angled lifting mechanism, in order to flip caps, within the VEX turning point game. The small robot also has to shoot balls towards a wall of flags. A flywheel was chosen, to send the ball flying towards the flags. Other mechanical applications can include a catapult or slingshot.

This is a screenshot of the frame for the small robot. Each team has a big and small robot. Based on the VEX turning point game manual, http://dreibeingmbh.de/wp-content/uploads/2018/04/VRC-TurningPoint-GameManual-20180427.pdf, there are caps that must be flipped, as well as balls that need to hit the flags.
Therefore, we had to plan a strategy for each robot, which includes, a specified game plan regarding what they should each focus on. After many days of brainstorming, and studying other robots, we decided to assign the big robot towards lifting, and the small robot towards shooting. This meant that the big robot would have a functional and advanced lifting mechanism, while the small bot contained an effective shooter (flywheel).
