Hi, I'm Yared Legese.

Cut inverter standby current from 2.3 A to 1.7 A (about 26%) through AES-mode configuration, saving about 184 Wh per day.

Reviewed solar and battery performance, including cycles per charge, battery life, and seasonal derating, and identified a low-temperature threshold affecting the battery self-heating circuit.

Prepared the I/O list, sequence of operation, and cause-and-effect matrix for gate operation, vehicle detection, and obstruction detection.

Improved overall energy efficiency by 18% through load calculations, equipment selection, and ASHRAE standards.

Reduced design errors by 25% and project delivery time by 20% with AutoCAD and SolidWorks layouts and clash detection.

Sized oxygen, vacuum, and compressed-air piping using pressure-drop checks and flow balancing to meet healthcare safety codes.

Supported engine calibration in MoTeC (fuel mapping, ignition timing, telemetry analysis), contributing to 12% higher torque and 8% higher thermal efficiency in testing.

Optimized intake and exhaust parameters in Realis simulation, reducing predicted exhaust backpressure by 15%.

Refined suspension geometry and drivetrain integration for handling and drivetrain efficiency.

Coordinated and mentored a 5-member team to a successful MVP demonstration, reducing prototyping time by 30%.

Conducted 60+ customer discovery interviews through NSF I-Corps, validating 70% of key hypotheses.

Placed in the top 20 of the SDM CEO Student Business Plan Competition.

Longitudinal pitch control for a fixed-wing aircraft, with state-space modeling and closed-loop stability analysis.

Altitude and full 3D trajectory tracking for a quadrotor, including hover stabilization and line and sinusoidal paths.

Multi-robot coordination: go-to-goal, breadcrumb path following, moving-target tracking, and consensus rendezvous.

Modeled a tubular A-arm with inboard frame bushing mounts and an outboard spherical joint for the upright.

Designed for chromoly steel (AISI 4130) and fabrication by welding or tube bending.

Checked camber control, suspension travel clearance, and steering geometry compatibility.

Assembled the chassis, motors, Mecanum wheels, motor driver, and ultrasonic and IR sensors.

Programmed the control logic to detect obstacles, stop, turn, and continue in a new direction.

Tested in a bounded space with obstacles and tuned sensor position, turning logic, and motor coordination.

Modeled a pinion gear with a splined shaft for torque transfer.

Built a planetary gear assembly with sun, planet, and ring gears.

Created rendered views of the parts and the assembly.

Set up the Sine Wave source block and its signal parameters.

Displayed and checked the output signal with a Scope block.
