Hi, I'm Asrith 👋

Robotics & Embedded Systems Engineer - I build systems that close the gap between simulation and real hardware.

MS Robotics @ Arizona State University. I work across the full stack: ROS 2 middleware, embedded firmware, real-time control loops, and perception pipelines.

📌 Featured Projects

Real-time locomotion control for a humanoid model, with PD controller gains tuned against USD Physics DriveAPI at runtime in NVIDIA Isaac Sim.

  • Stack: NVIDIA Isaac Sim · USD PhysX DriveAPI · Python · ROS 2
  • What it proves: Sim-to-real pipeline, humanoid dynamics, runtime control loop debugging
  • Key challenge solved: High PD stiffness values caused joint oscillation in the PhysX contact solver; diagnosed by logging DriveAPI torque outputs per joint, identified the stiffness/damping ratio was mismatched to the inertia parameters, and retuned gains live without resetting the simulation.

Goal-oriented autonomy on TurtleBot4: an ESP32 IMU module streams positional goals over serial to a ROS 2 node, which feeds the Nav2 stack for real-time obstacle avoidance and SLAM-based navigation.

  • Stack: ROS 2 Humble · Nav2 · SLAM Toolbox · ESP32 · Python · pyserial
  • What it proves: Hardware bring-up, cross-device ROS 2 communication, full nav stack deployment on a physical robot
  • Key challenge solved: ESP32 serial output occasionally dropped or malformed packets under USB load, causing the goal publisher node to crash; added input validation and reconnect logic to the serial parser so the nav stack recovered gracefully without requiring a restart.

Perception-to-motion pipeline for a 6-DOF arm: camera input → YOLOv8 detection → MoveIt trajectory execution.

  • Stack: ROS 2 · MoveIt · OpenCV · YOLOv8 · PyTorch · OMPL · Inverse Kinematics
  • What it proves: End-to-end perception + manipulation, real-time CV integration
  • Key challenge solved: YOLOv8 inference latency on CPU caused the arm to plan trajectories against stale detections, leading to grasp misses; moved inference to a dedicated thread decoupled from the planning loop, cutting end-to-end delay and eliminating the lag-induced misses.

Safety interlock system for an industrial robot cell: EKF state estimator feeds a watchdog relay via Modbus TCP, running IEC 61131-3 Structured Text safety logic on OpenPLC.

  • Stack: Python · Modbus TCP · IEC 61131-3 · Plotly Dash · EKF · Docker
  • What it proves: Industrial protocol knowledge (Modbus/PLC), control system safety design, sensor fusion
  • Key challenge solved: Raw encoder readings fed directly into safety interlocks caused constant false alarms from sensor quantization noise; built an EKF from scratch (numpy only, analytic Jacobians, Joseph-form covariance update) and added NEES chi-squared consistency monitoring, giving statistically grounded filter health checks rather than visual inspection.
