Team 2590 Nemesis is proud to present our 2017 Robot “Eris”

Check out our Chairman's Video!

Nemesis’ 2017 robot Eris features an articulating intake, climber, gear manipulator, and a triple flywheel shooter. The intake consists of compliant and mecanum wheels that utilize the bumper to center the balls into a hopper. Four urethane belts on the intake pull the balls into the hopper which is all belted and powered by a versaplanetary gearbox. The hopper is designed to hold 50 balls and consistently feed balls into the shooters.

The drivetrain is powered by two modified VEXPro ball shifters, run by two CIM motors each. Capable of 6 feet per second for fine adjustments and pushing matches and 14 feet per second for cross-field runs and high agility. Shifting is controlled by pneumatic pistons for seamless transition between gear states.

Eris’ intake is an over-the-bumper style intake. Actuated by two pneumatic pistons and powered by a single 775pro motor, the intake glides just above the height of the balls, sweeping up fuel with ease.

Powered by two 775pros belted 3:1, Eris’ shooter fires at a rapid and consistent rate. The three shooter wheels are urethane rollers that compress the ball ½ inch. Static at a fixed 87 degrees, the shooter is optimized for shooting from a few specific locations.

A shaft wrapped in double hook velcro powered by two 775pros allow for a swift three second climb. A reversible ratcheting wrench prevents backdrive and easy detachment from the rope.

The Gear manipulator employs two pneumatic powered pistons that actuate wings that keep and release the game piece. A slot exists to enable quick cycles from the human player station to the airship.

Implementing autonomous scripting allows Eris to choose from multiple different autonomous routines. The adjustable and diverse range of autonomous actions make Eris the perfect fit for any alliance.

Eris will be competing at Hatboro-Horsham, Springside Chestnut Hill, and Montreal.
