Emil Sahel developed and refined core actuation subsystems for FRC7902/Offseason-Reefscape2025-Team-Fire, focusing on elevator and arm mechanisms with an emphasis on safety, reliability, and simulation fidelity. He architected and integrated elevator and arm controls using Java and WPILib, implementing PID tuning, CAN bus sensor feedback, and safety interlocks to prevent unsafe operations. Emil enhanced simulation support to align virtual and real-world behavior, enabling faster iteration and safer testing. His work included subsystem design, constants management, and command-based framework refactoring, resulting in more predictable autonomous and teleoperated performance and easing future tuning and maintenance for the robotics codebase.

Sep 1, 2025September 2025 performance summary for FRC7902/Offseason-Reefscape2025-Team-Fire: Focused on safety, reliability, and control accuracy for the elevator subsystem and algae intake. Delivered Elevator-Arm Safety Interlocks with a refactor of MoveElevatorArmCommand to account for arm angle, plus ArmSubsystem SysId capabilities for tuning. Completed Elevator Control Tuning and Height Configuration with calibrated constants, expanded max height, refined L1-L3 setpoints, and tightened motion constraints, validated on real robot. Improved Algae Intake reliability by removing unnecessary timeouts and ensuring stable operation across elevator positions and algae presence. Simplified Rotation Control by removing elevation-dependent rotation speed scaling to reduce coupling with elevation state. These changes enhance safety, predictability, and field performance, enabling more consistent autonomous and operator-driven tasks and easing future tuning.

Aug 1, 2025August 2025 performance summary for FRC Team Fire (FRC7902). This month focused on delivering core actuation subsystems, enabling safe and reliable automated moves, and strengthening simulation fidelity to reduce hardware risk and accelerate testing. Completed architecture for Elevator and Arm subsystems, integrated into RobotContainer, enhanced CAN-based sensing, added current limits, and tuned PID controllers for both arm and elevator. Implemented safety triggers for enumerated and meter-position moves, and established groundwork for MotionMagic-based arm control in simulation. All changes are designed to improve reliability, predictability, and alignment between simulation and real-world behavior, enabling faster iteration cycles and safer autonomous/teleoperated operations.
