Robotics & Mechatronics Engineer

Key Responsibilities

• Design and tune PID control loops for stability, responsiveness, and robustness across flight conditions.
• Define control objectives and performance metrics tied to safety and spray accuracy.
• Develop control logic that accounts for real-world disturbances, saturation, delays, and sensor noise.
• Support integration of control algorithms into embedded implementations in partnership with firmware teams.
• Build dynamic models of the platform and subsystems (actuators, sensors, airframe responses) to inform control design.
• Perform stability analysis using frequency-domain techniques (e.g., Bode plots) and converge on stable operating regions.
• Develop and validate sensor/estimation assumptions (rate limits, latency, noise characteristics, update timing).
• Use MATLAB or another scripting language to prototype and evaluate control loops and tuning approaches.
• Document modeling assumptions, control architectures, and tuning rationale for repeatable engineering decisions.
• Build and run simulations (including dynamic simulation) to validate control strategies before field deployment.
• Design test plans for tuning and validation, including step responses, frequency sweeps, and disturbance testing.
• Support field testing and iterative tuning under agricultural environments (shock, vibration, wind, dust).
• Analyze test data to identify instabilities, coupling effects, and performance bottlenecks; implement improvements quickly.
• Work closely with Embedded Engineers to ensure real-time constraints, sensor timing, and implementation details match control intent.
• Collaborate with Mechanical and Electrical teams to align actuator/sensor selections and physical constraints with stability needs.
