Meet HELIOS: The #16th ranked FRC robot in WA, OR, + AK!
Highly Efficient Launcher and Intake Oriented System
- Has two axes of freedom, one that adjusts the rails that the ball rides on, and one that adjusts the angle of the flywheel
- Has an 85% accuracy in autonomous and with a full load of balls 70% in teleop
- Primary structral components made out of Baltic Birch
- Cut using a CNC
- Uses a CIM without a gearbox to get the necessary torque without RPM reduction
- Uses a Banesbots T81 wheel for the flywheel
- 10:1 gear ratio on a BAG motor
- 1” Urethane belts (6)
- West Coast Products roller system
- 1.25” drum
- 19” wide- room for ~4 balls at once
- Yoga mat as padding for the back wall
- 14 inch diameter baseplate wood ~6” tall aluminum sides
- Snowblower motor
- 6” x 2” paddles (4)
- 17.5” shaft up middle
- Roller to reduce jams
Climber and Rope
- CIM Motor
- 35:1 gear ratio
- 1” drum diameter
- Brake incorporated for safer lowering
- Ratchet incorporated to allow motor to be stopped at the top of the climb
- Approach for climber to catch rope: Hook side of Velcro on climber drum + polypropylene segment of rope at the bottom that acts as the loop side of Velcro
FAQs about Helios
What can your robot HELIOS do?
- Shoot (about 70%-80% accuracy, with storage capacity of about 35 balls)
- Intake from the ground and from the hoppers
- Place gears (passive holder allows us to retrieve gears from human players, but not the ground)
- Climb (can easily complete in under 10 seconds once rope is acquired)
What part of the field do you prefer to play?
Shooting right up against the boiler (in the key). We can also retrieve and place gears.
What do you do during autonomous?
We have 3 options.
- Shoot 10 balls into the boiler (~80% accurate) and cross the auto line
- Place center gear (less reliable, but doable if aligned correctly)
- Just drive straight across the line
What’s your drivetrain?
Six-wheel drop-center, belt-driver, 4 CIMs. Nothing fancy, but it gives us plenty of speed and maneuverability on the field. Gear ratio of ~8:1.
Have you had any problems with HELIOS?
It took us a while to tune our launcher, and have had to deal with wear and tear on the launcher flywheel and intake belts.
What’s the coolest part of your robot?
We’ve got a pretty sweet climber.
What programming language do you use?
Why is your robot called HELIOS?
Since our first robot - ATLaS - Spartronics (a derivative of Spartans or Sparta, from ancient Greece) decided to relate our robot to Greek Mythology and name our robots after a Greek deity.
Each robot name is also an acronym, based on the robot’s unique capabiliities or features:
- ATLaS - Advanced Tele-operated Launching System (2014)
- GAEA - Grabbing Actuated Elevator Automation (2015)
- ARES - Advanced Robot Engineered for Siege (2016)
- HELIOS - Highly Efficient Launcher and Intake Oriented System (2017)
