Throughout build season, Team Operations has been working on rebranding the team by changing our logo to accurately represent 4909’s image. The team has continued to create and release safety quizzes each week. Read more about our safety program in our website’s safety section. Members have also been working on our submission for the Woodie Flowers Award. The Woodie Flowers award recognizes an FRC mentor who demonstrates “gracious professionalism” and inspires students in the principles of engineering. Team Operations has also begun to prepare for the competition season. This includes writing our team business plan, safety plan, and more. In addition, the group has been planning outreach events and fundraisers, so be on the lookout for more information in the coming weeks!
The shooter group has made a lot of progress with their CAD and started manufacturing parts this week. The beginning of the week heavily focused on making progress in CAD. Members designed the pneumatic system for the two-position flip-up hood, and added a motor and pulley for the indexer wheel. The group determined the best way to mount the shooter onto the robot by making custom gussets and creating a mount for the light. Students worked with the software group to add sensors such as a color and beam break sensor. At this point, the shooter design is complete, so members have started manufacturing parts like box beams, hex shafts, and support beams. The intake and climber subsystems have been integrated into the shooter CAD, and students are finalizing their designs today with design reviews.
This week, the intake group finalized the geometry needed for the four bars used to deploy and retract the intake to fit inside the robot. Members then integrated the intake assembly onto the final robot CAD. The group looked at different options for gas shocks, and after testing a few out, ultimately decided which one best fit the group’s needs. After color-coding the shafts and other parts of the intake, the group attached multiple components including a neo 550, compliant wheels, and belts. Before installing some of the components like the belt, the team had to design and add on spacers. Members calculated the gear ratio for the neo and decided the placement of the mechanum wheels so that they center the cargo as it comes in contact with the robot. At the end of the week, the group discussed where to place the piston on the intake so it can extend and retract.
The climber group spent this week redesigning the hooks the robot will use to climb the hangar. On Monday, members split into three groups; two worked on static hook designs, and one worked on a dynamic hook design. After discovering their designs did not work halfway through the week, the static hook groups decided to brainstorm alternatives. The static hook is now complete in CAD, and members have been fixing some bugs in the dynamic hook CAD. The team plans to hold a design review for the climber subsystem next week.
