Week 1 Build POVs

This year’s Kickoff was the first I’d attended, yet it wasn’t difficult to feel closely involved with the process – we all had the opportunity to brainstorm prototypes for this year’s robot, and doing so really helped me think critically about the game and the potential mechanisms that could be used. During the week, my prototyping groups came up with a mechanism resembling a hug, a system using rollers to move the power cube, and others; after that, my committee (programming) set to work getting all of our devices up to speed for this year’s game, and considering potential sensors to implement and how to code them. Many people envision robotics as the frantic rush of physically constructing a robot, but this week allowed us to experience the careful planning and diversity of ideas that go into creating a viable design, which is just as critical.

The first week of build season has gone by really fast. Electronics has been doing  research about sensors that we might be using for this year’s game while mechanical finishes prototyping. We’ve also been working on small projects that branch out from electronics which has been engaging and fun. This year’s game is really interesting and I’m looking forward to our strategy and seeing how other teams plan theirs.

By Elizabeth Fernandes ’20 and Angela Zheng ’20

The Janksters kicked off the build season by gathering together to watch the FIRST live stream. Everyone was ecstatic to learn the new game challenge for this year. After watching the reveal video, mentors got busy to build a mock game playing field with the students. These games allowed the students to try out different strategies as well as to get a better understanding of the game. After analyzing this year’s game, the Janksters split up into groups to brainstorm ideas for the robot and started by coming up with a list of things the robot needs to accomplish as well as some possible mechanisms they can use to accomplish those tasks.

Mechanical split into the different subgroups based on this year’s game. The subgroups include: Chassis, In n’ Out, Many Projects, and Up and Down.

The chassis subgroup discussed with the Up n’ Down and In n’ Out groups about having an open or closed chassis and decided on having a closed one. They figured out the range of the gear ratio, approximately how much space each chassis element will take up and where the other mechanisms will fit, finalized the type of wheels. They finalized certain decisions regarding chassis and ordered the gearbox.

The In n’ Out group brainstormed various potential mechanisms to get the power cube off the ground and onto the scale, switch or exchange. After making a list of evaluation points for each idea, they narrowed down their options to using a claw or rollers. They completed prototyping the claw mechanism and began a prototype that uses rollers.

The Up n’ Down group researched various mechanisms that can be used to move the power cube up and down and decided on either sliding tracks or a jointed arm. They created a list of requirements for the mechanism and did the calculations for each idea. After making CAD drawings and prototypes, they decided that the sliding tracks are preferable because it is more simple and reliable.

This week, the Many Projects group focused on choosing which game components to build and how to construct them. After exploring the various options, they decided on building the exchange and its platform as well as modified versions of the switch and scale. Then they created a materials list of all the parts needed for each component with all of the measurements. They anticipated how much space is needed to store the game components and potential areas around campus that can accommodate them.

The programming committee installed the CTRE library and updated the 2018 Eclipse toolchains and plugins onto their personal laptops. They updated the team’s driver station laptops for this season. They fixed the CANTalon errors and started adjusting the syntax from previous code to accommodate the changes. They researched encoders, gyros and the USB camera and practiced programming limit switches. They discussed vision with mentors and concluded it would be beneficial due to the complex autonomous this year.

The electronics committee determined which sensors they could use, compiled a list of necessary sensors, which are touchless sensors, encoders, and sonar, and discussed limits on the vision tracking. They came up with new materials they need for this season and labeled and organized the new components in the Kit of Parts. They worked with the chassis group to figure out spacing and encoders and talked to the programming committee about gyros and sensors. They fixed issues on the driver station CAD and did a design review. They repaired the pneumatics board pole and battery mount and added final brackets onto the battery cart.

The business committee began brainstorming design ideas for the front and back of the shirt and buttons. They designed concept art that incorporates elements from the game challenge. They developed a concrete plan for the Chairman’s Award with deadlines and who will be involved in the writing and editing process. They began editing chairman’s and analyzed other teams’ techniques. They did further research on giveaways and narrowed down the list to screwdrivers, logoed tape, a mini first aid kit, post-it notes or a screw checker. They took photos and videos for social media and next week’s video update.

Week 6 Build POVs

It’s crazy thinking that this is my last build season! Week 6 means crunch time so we’re all scrambling to make last minute decisions and putting the finishing touch on our robot. It’s really different this year for me since I’m on Business now instead of Mechanical so the stress of putting actual items on the robot isn’t as big for me. However, there’s still a lot of planning and details that need to be worked out for my assignments. I can’t believe my last Build Season is coming to a close. It’s been an interesting one definitely but I’m glad I got to know my teammates better and gain new skills.

This week, we have mostly worked on manufacturing parts for our second robot and making some final decisions and changes. It has been really stressful, but all the chaos is exciting at the same time. It’s strange that I’m already about to end my third build season and I can tell that I have grown so much since freshman year.

Plagued with a mixture of nerves and excitement, I remember heading to kickoff at San Jose State, just six weeks ago. Now, after countless hours of trudging to school, I can’t believe I’m saying this, but I want more time! After finishing driving and manual two speed transmissions code, our chassis programming group’s latest challenge is working on programming automatic two speed transmissions. We’ve been working on mapping the correlation between joystick values and encoder rates for driving our test robot. I’ve also been working on combining all of this season’s code into one comprehensive project, a task that has been tedious but rewarding to complete. Though it’s exhausting, the moments of success, growth, and joy that pop up during the rigor and intensity of build season are what constantly reinforce my love for robotics.

On week 6 of Build Season, I mainly focused on CADing the front and back camera mounts and had help from Ayusha, Becky, and our mentors. Because there was some last-minute updates about the mounting place of the camera, each of the camera mount had to be modified several times. Although we had to build several versions of each of the two different camera mounts, my skills in CADing had improved a lot, my critical thinking in designing a mount has improved, and my confidence in CADing has grown. Now that Build Season is coming to an end, I feel that the excitement is starting to lower down, but I am looking forward towards the Steamworks competition.

In the fifth week of build season, the Janksters have been nervous about the dwindling number of days left in the countdown and are motivated by the close finish line, a completed robot.

Programming has been busy coding for the various mechanisms and have successfully completed the ones for climbing, chassis, and all five pistons for gears and fuels. They are starting to test the more complex components of the programs.The committee was able to see black and white images on their vision processing system and even test their driving program on the electronics board!

Electronics, on the other hand, finalized CADing of the electronics board by making minor adjustments. After putting the components onto the board, they worked on encoding and wiring, and they were able to put the board on the robot. They additionally worked with Programming to test their limit switch and pistons.

The Business committee has made finishing touches, such as submitting the Woodie flowers award, creating the jacket designs, and sending out Robot Reveal invitations. With Robot Reveal coming up this Saturday, they are working on the presentation, making bows, and updating social media.

Meanwhile, the Mechanical sub-groups are wrapping up multiple projects:

Climbing has mounted their entire mechanism and ran tests on them to ensure it was working properly. They are now starting to work on building a cross-beam and will soon begin assembly for the second robot

The Gear and Fuel group has finalized their mechanism designs with a few adjustments to their original plan. They are working on CADing and building the various elements, such as the sliding track and fuel chute. At the Tech Shop, they were able to laser cut and assemble new pieces, and they are now finished with CADing the gears, mounting holes, and building the fuel storage.

Many Projects is starting work on the battery cart and finished CADing, creating, and mounting the bumpers for the robot.

Since finishing the chassis, this committee has worked on CAD and fixed the gearbox and bearing. They are now preparing to build the second robot by updating the robot assembly on CAD and drilling holes into beams.

The team looks forward to working harder than ever in the last week of an exciting Build Season.

The third week of Build Season is over and the committees have been working hard on finalizing CAD and moving forward to manufacture the components for the robot.

Programming has been busy coding for different sensors on the robot. They’ve programmed for the gyro-sensor, accelerometers, 5 different encoders and driving for a 6-wheel robot. They’ve also worked with image sensing and cameras to combat the issue of low visibility with this year’s game.

From changing their board size and configuration to finalizing encoders and sensors, Electronics has been quite busy during Week 3 of build season. They successfully completed the electronics board for the programming chassis. They also did research on temperatures sensors, encoders, and sonar sensors. They started brainstorming and CADing different mounts that they’ll be using for their cameras. Electronics also completed CADing one of the boards that will be used on the final robot.

The Mechanical sub-groups have worked to finalize their CAD design and wrap up several projects.

Chassis has recently been anodizing wheels. They have made and tested their third gear box. They are working on bumper mounts and with CAD, putting all of their parts on the software.

Many Projects has assembled a mock chassis for testing and they’ve also built field elements for practice. They’ve finished a loading station and lift. They’re currently working on making bumper mounts and organizing the rope for the Climbing group to test their mechanism on.

The Gear and Fuel group are finalizing their overall CAD and how their mounting is going to work. Measurements are done and ready for laser cutting and now they’re focusing on volume measurements to maximize fuel storage.

The Climbing group has been dealing with constant changes to their designs. After much talking with Electronics and Chassis, they have almost completed CADing, with plans to finish today, and have been ordering parts.

The Business committee has been working on their designs for Janksters shirts and the standard and they have finalized this year’s button design. They are also working on team bows and helped design and assemble the bumpers for the robot.

The second week of Build Season has passed and the committees have been working hard on designing and CADing the different components of the robot.

The Programming Committee furthered their research in camera sensing and were able to make the cameras work with SmartDashboard which the Drive Team uses on their computer. They also communicated with the different mechanical groups on what they needed programmed and looked more at sensors which they are looking at testing on a chassis next week.

Electronics has been working on getting their CAD done so they have an idea of how they are going to fit their components on the robot. They have also worked with programming to see what kind of sensor they’ll need to make the robot’s driving efficient and they have completed a wired chassis for them to test their code.

The Mechanical sub-groups have been working hard on CADing and building projects for the robot.

The Climbing group has been doing a lot of math to calculate their new design. They’re currently working on testing and finalizing the details of gearboxes and hooks so that they can CAD a model.

The Chassis group has been CADing their chassis and working on making gearboxes. They have also made a chassis with Electronics for Programming to test their code on.

The Gear/Fuel group has been working on finalizing measurements and spacing so that they know how to securely mount all of their mechanisms and how placement of the pistons will work. They’ve also been testing different motors for intake of fuel while comparing size and efficiency. They’ve been making progress on the CAD models as well.

The Many Projects group finished building a loading station for the Gear/Fuel group and have made a lot of progress on the lift. They are also building a test chassis to work out the spacing and center of gravity for the robot.

The Business Committee has been working on designing shirts, buttons, and more on Illustrator and they’ve also been making bows and finalizing giveaways.
