Designing the Arm in Onshape

On Saturday, January 13th, we had our first Saturday meeting since kickoff. After voting and finalizing our design for our robot the day prior, we now had to start focusing on designing and prototyping the robot in CAD. Our design will have ground intake, be able to shoot in the amp and speaker and hang on the chain. Design and Fabrication (DAF) split up into three groups to start designing the robot's subsystems in Onshape: the chassis, the arm, and the intake/shooter.

In the arm group, we modeled our design in CAD and worked out the dimensions and placement of the arm after discussing it with the other groups. We had to change our initial dimensions after changes from the other groups and the placement had to be rearranged because the arm base would have interfered with the swerve drive. Afterward, we started to look at gear ratios to help move our arm instead of a chain mechanism. We made a rough plan of the gear ratios in the Google Sheets Calculator, and next meeting, we can add it to the CAD to see if the gears will all fit and work from there.

Build Season - Week 3

The third week of the build season has been a whirlwind of activity for every department of Charge Robotics! Our team is hard at work prototyping subsystems and writing code to meet our competition goals. Here's a look at what each department has accomplished: Design After countless hours in CAD, the Design team has completed the elevator and chassis subsystems. The elevator system is a game-changer, incorporating a coral intake system capable of reaching four reef levels, which will save valuable time during matches. However, the team is reworking the robot's hanging mechanism, having decided to pivot from the tow truck design and explore new options for deep hanging. Fabrication The Fabrication team is ready to start building as soon as the Design plans are finalized. In the meantime, they are tackling smaller components, like preparing the robot's bumpers and gearboxes. Software The Software team is wrapping up code for the elevator system and has implemented a library t...

Build Season - Week 4

  The Charge Robotics Team has been firing on all cylinders this week! The team has finished some projects, but many are still being designed and built. Design The Design Department has been busy CADing our robots' coral intake, bumpers, and various custom parts like gussets, plates, and pulleys. Our coral intake utilizes spinning cylinders that spin forward and backward to intake and release coral. While the bumpers only protect our robot from impacts. Our custom parts are crucial for our robot subsystem's functionality. Fabrication The Fabrication Department is busy building our elevator. The elevator allows us to reach all four levels of the coral reef. It also comes with the ability to be compatible with our coral intake;  meaning our elevator and coral intake function as one subsystem increasing our efficiency. Software  The software department has finished our elevator code and our hanging subsystem code. They are testing automatic routes to allow the robot to move ...
