Job Description

robotic control systems

Core Technical Responsibilities-

Robotics Kinematics & Dynamics

  • Forward and inverse kinematics (serial/parallel manipulators, mobile platforms)
  • DenavitHartenberg (D-H) parameterization, transformation matrices, SE(3) frames
  • Inverse dynamics using Newton-Euler and Lagrangian methods
  • Multi-body dynamics modeling, Jacobian computation, singularity handling
  • Constraint resolution for underactuated or redundant robotic systems
  • Dynamics compensation for payload variation and external disturbances

Control Systems Design

  • PID, cascaded PID, feedforward + feedback hybrid control
  • Linear state-space modeling, controllability and observability analysis
  • LQR, pole placement, and optimal trajectory stabilization
  • Model Predictive Control (MPC) basics for path tracking
  • Sensor feedback loop integration (encoder, IMU, force-torque sensors)
  • Saturation, anti-windup, slew rate limiting, and safety interlocks

Estimation & Sensor Fusion

  • IMU + magnetometer + GPS fusion using complementary filters or Kalman filters (EKF/UKF)
  • Dead-reckoning, drift compensation, and heading estimation
  • Odometry tracking for differential drive, Ackermann steering, and holonomic bases
  • Sensor latency calibration and outlier rejection filters
  • Covariance propagation and uncertainty bounding
  • SLAM or VIO pipeline understanding (bonus)

Math Tools & Simulation

  • Proficient in

    Eigen

    for linear algebra (matrices, quaternions, decompositions)
  • Use of MATLAB/Simulink, Python (NumPy/SciPy), or C++ math libraries
  • Simulation using Gazebo, Isaac Sim, Webots, or custom physics engines
  • Motion planning algorithms: A*, RRT, potential fields, trajectory smoothing
  • Testing with synthetic sensor injection and disturbance modeling

System Integration

  • Interface with embedded firmware teams for control loop integration
  • Tuning control loops for real-world timing, actuator limits, and environmental response
  • Coordinate frame management (NED, ENU, body-fixed, camera frames)
  • Deployment onto real-time OS or Linux-based compute nodes (ROS 1/2 stack)
  • Real-world calibration procedures: encoder zeroing, IMU alignment, gain tuning

Tools & Frameworks

  • ROS 1/2 (navigation, tf, control, message transport)
  • RViz or 3D visualization tools for debugging
  • Git, CMake, and CI pipelines for code validation
  • Logging, playback, and telemetry analysis (e.g., rosbag, custom log viewers)

Preferred Qualifications

  • B.Tech / M.Tech / Ph.D. in Robotics, Control Systems, Mechatronics, or Applied Mechanics
  • 3–7+ years of robotics control and estimation experience
  • Strong background in applied mathematics and physical modeling
  • Experience with robotic arms, mobile robots, UAVs, or hybrid autonomous platforms
  • Publications or project contributions in control, planning, or estimation domains
