Looking for new Outreach/Business members!
Throughout the season, we went through many iterations and design ideas before arriving at our latest one.
The main and most important iteration out off our old designs is the claw.
This claw is simple, strong, and effective, making it a great choice for this FTC season and helped us score efficiently in our last competition. While it works well for both samples and specimens, we realized the arms needed to be longer for easier sample grabbing, prompting us to explore a new design.
The design we used for our second competition is the intake wheel.
After our first competition, we realized our initial design was inefficient, so we immediately brainstormed a faster and more effective solution for the next event. Focusing on samples to maximize points, we designed an intake mechanism to efficiently "suck" in samples and integrated a bucket system with Viper slides to accurately lift and deposit them into the high basket.
Over the summer, we mastered 3D design and created a custom drivetrain. We implemented a live axle drivetrain that depended on the rotation of the axle to propel the wheels. However, we soon discovered that this design created excessive friction, which ultimately decreased the wheels' speed. During the season we then switched to a belted dead axle drivetrain to improve speed and configurability. The dead axle drivetrain reduces the friction by making the axle stationary or “dead”.
