581 Blazing Bulldogs | Behind the Bumpers | FRC CRESCENDO Robot

Summary

In this video, the 581 Blazing Bulldogs team showcases their impressive robot designed for the daily division. The robot features an under-bumper intake, a pivoting shooter, and an angled climber. They discuss their intake system inspired by Team 6328, utilizing a smaller roller diameter and 3D printed parts for better grip. The video also covers their climbing mechanism with a diagonal linear actuator and a unique 'Jackhammer' roller for consistent scoring. Additionally, the team talks about their shooter with 1/8-inch polycarb flywheels wrapped in grip tape and the use of vision systems for accurate shooting. The script concludes with a mention of various autonomous modes they have developed for the season.

Takeaways

• 🤖 The 581 Blaze Bulldogs are currently in sixth place in their division with a robot featuring an elevator, trap mechanism, pivoting shooter, and angled climber.
• 🔄 The robot's under-bumper intake system is inspired by Team 6328 Mechanical Advantages, with modifications including a smaller roller diameter and 3D-printed core.
• 🏗 The intake mechanism uses a cat tongue grip tape for better control and can feed the note into the shooter or the amp mechanism by reversing the roller direction.
• 🎯 For scoring, the robot has a trap mechanism that uses the same intake system to score notes into the trap.
• 📈 The climber mechanism is a diagonal linear actuator with a 12.6:1 reduction gearbox for power and speed, going through multiple stages to climb.
• 🔩 The robot uses 3D-printed Onyx material wheels from Markforged, chosen for their strength and lightweight properties to stay under the weight limit.
• 🏹 The shooter features 1/8-inch polycarb flywheels wrapped in cat tape for grip, controlled by four motors for variable spin rates.
• 👾 The software includes a shuffling autom for note passing, Megapixel vision system for feeding shots, and uses TX and TY for 2D math and speaker shots.
• 🔍 The robot is equipped with a note sensor for dynamic autonamous operations, detecting the presence of a note to decide the next action.
• 🔄 The team has adapted their autonomous modes throughout the season, with a variety of auto modes designed for different field positions and strategies.
