Helios

Team 2637 introduces its robot: Helios. 2637 has combined its past successes with new innovations -- adding a turreted shooter with vision while retaining to its tried-and-true WCD.

The Phantom Catz competed at Ventura County, LA Regional.

Strategic Approach

At kickoff, the team determines an "ideal alliance," listing mechanisms for three robots that we believe will win an Einstein match scenario. This season, we determined having a turret, aiming mechanism, and high goal shooter as being essential in that alliance. 

Robot 1, Robot 2: Score at least 2 cargo in autonomous, shoot from anywhere on the field, and have the ability to traversal climb.

Robot 3: Score at least 2 cargo in autonomous, play defensively, hoard, and be able to traversal climb.
