Week 3
Jan 22 2022:
Our team worked on solidifying our climb concept that influenced the geometry of the entire robot. The feasibility was challenged and supported via the spreadsheet created by our students. They summarized the motor specifications and gear ratio required to make the climb work. The mentors challenged the manufacturability of some of the components. The students responded with potential sponsorship support and new equipment that would potentially enable the capability to be done in house.
The climb system initial extension was discussed in detail. The initial stage will be deployed with a spring release system. The guides will be bearings or cam followers to support the elevator track. The mounting of gearboxes and pivot points were also outlined.
The extended intake modeled the movement of the ball over the bumper and created a profile for the intake axles to mount. The internal ball processing was also discussed in depth through various options such as a carousel or a in line model . The use of mecanum wheels could be used to center the ball.
Jan 24 2022:
Programming team set up a gyro. They utilized some spare material to create a mount for the gyro. Adding a couple clearance holes they fastened the gyro in place and now it was ready for testing.
The field element build is nearly complete. The two tiers are upright and the posts are nearly ready to be set in.
The wood prototype robot received additional structure updates. The shooter support and the shooters metal frame were updated based on feedback from the meeting on Saturday.
Students were able to create a model for the extended intake axle that included compliant wheels, spacers, hex shaft, and bearing mounts. The model will then be added to the full extended intake assembly once mounting holes are added.
Jan 25 2022:
We received our Table CNC from Forest Scientific today. We spent 3 hours of our work session learning the operations of how to do engraving, pockets, and cutting through shapes.
The shooter prototype received a motor mount, and was connected to our controls system to run tests. We noticed our robot could shoot from 8ft-18ft from a fixed angle of 30 degrees. We will be also conducting tests at 45 degrees once our laser is back up and running.
We've added more detail to our Shooter, Climb, and Intake sub assembly models. The mounting and coordination since our meeting on Saturday has fueled our progress.
Jan 27 2022:
Programming team worked to get the vision tracking system code functioning. They proved the Limelight would follow the vision target to turn the turret both left and right to keep the target centered.
The CAD team worked to improve the models for all the sub assemblies. The Climb team added constant force springs, modified their custom gearbox, and began troubleshooting the pneumatic hook design.
The Shooter team mounted motors with axles, and modified the mounting for the pneumatic hood.
The extended intake reviewed the pivot points of the linkage system, then looked to add a cylinder to actuate the movement.
The Base team added ROCK BLOCKS to mounting points, and created mounting holes.
The intake team investigated a curved guide vs a pulley belting system. The belting system has proved to be more beneficial for control and cycle speed upside.
Jan 28 2022:
We were invited to a breakfast event from Butler Tech. The goal of the meeting was to bring together students, teachers, industry partners, and stakeholders to talk about career technical education. Students talked about their experience that led them to career tech, industry mentors talked about desired skills for coops, and P&G presented a wide range of job opportunities that will be available to students in a wide range of programs offered at BT.
Our raw material came back from Powder Coating Specialty and came back looking great! The material was taken care of with clear plastic wrap and foam around the materials for safe transport. Excited to engrave the sheet metal with our laser for parts this year.
