Our mechanical and electrical teams split up into four different teams each assigned a specific prototypes. They worked on the design and initial builds of a scissor-lift/winch system or 2-Bar/winch system for climbing and an elevator system or conveyor clamp system for power cube control.
Because this is the first year that the Techno Titans have built a scissor lift to use on an FRC robot, this team did not have any past history to reference. Instead, they referenced online FRC forums and engineering websites as well and went through multiple iterations of trial before beginning construction. They drafted a singular joint of the scissor lift and began construction on a wooden model.
The "conveyor clamp" is the beginning prototype for the mechanism that will intake, carry, and place the power cubes. The design uses a belt system to suck power cubes into the robot and pistons to open and close the grasp. A second set of pistons raises the mechanism vertically so the robot can travel with the power cube closer to the robot's center of mass. Today, they drafted the initial design and sketched it in Solidworks.
They also started the wooden prototype of this design.
The elevator lift is the main mechanism used to place power cubes on the scale or the switch. The final design is a cross between an elevator design and a telescoping arm. Today, they worked on the construction of a full-scale wooden prototype to prove that we can execute a similar system on the official robot.
This design is another possible system for climbing. During the strategy meeting, the scissor lift and the 2-Bar design were isolated as the best options. Both of these designs do not bear the brunt of the climb but rather deliver the end of a rope to the hook which then allows the robot to use a winch for the actual climbing.
The programmers met today and decided on their game plan for the next semester. Their main focus this year was determined to be improving their autonomous algorithms and implementing programs that allowed the team to have more deliberate control over the distribution of current. They also plan on anticipating the possible issues of competition and having code ready to go for multiple situations. Today, they worked on improving their automatic collision detection software.
They outlined Chairman's Essays and began media production to visually record progress. Business also began the possible design of an app that is based around the theme of Power Up. Their main concentration this year is to showcase our team's outreach events and our sponsors as well as build a local community of STEM students based around FRC.
