AUTONOMOUS LEAD | MOTION PLANNING AND CONTROLS, DEEP ORANGE 10
Deep Orange is hands-on project-based learning focused on systems integration and innovation sponsored by Ford Motor Company. As the Motion Planning and Controls lead for the project, my responsibilities include but are not limited to:-
•Perception, Planning & Control Development - Leading development of autonomous software stack for L4 Autonomous Vehicle, towards Lane Keeping, user selected Autonomous Parking, parking spot detection, and planning in any orientation. Integration with Powertrain, Human Machine Interface, and Vehicle Dynamics teams.
​
• Motion Planning & Control Software - Developed motion planning pipeline in C++/Python implementing Mission Planner, modular Behavior Tree, Hybrid State Astar and S-curve based Trajectory generation, and Stanley/Pure-Pursuit based hybrid lateral control. Simulated on Gazebo, followed by Golf cart testing and DO-10 vehicle testing.
​
• Autonomous Systems Integration - Sensor and hardware integration with NVIDIA DrivePX2, Velodyne LIDAR's, Cameras, GPS, IMU's and dSPACE MicroAutoBox II on ROS framework utilizing CAN and Ethernet communications.
Jul 2015 - June 2017
SENIOR ENGINEER - CONTROL STRATEGIES, BAJAJ AUTO LTD.
Bajaj Auto Ltd is one of the biggest two wheelers and three wheelers OEM in the world. As part of the Control Strategies team working on developing in-house Automated Manual Transmission, I worked on a lot of algorithmic and hardware testing, including:
​
• Algorithm Validation and Diagnostics - Responsible for developing algorithms in C to validate and diagnose Automated Manual Transmission's control strategies and associated hardware having production level variations. Post processed the data using MATLAB to plot trends and come up with thresholds for maintenance and performance vitality.
​
• Electronic Throttle Control's (ETC) Development - Tuned and improved the ETC feedback map using diagnostics data. Co-developed the ETC feedback-feedforward control algorithm for improved steady state and transient control.
PROFICIENCY
ALGORITHM DEVELOPMENT AND TESTING
C++, C, Python & MATLAB
With experience in programming from undergrad to writing production-ready diagnostics code in C at work for two years, and finally to masters where the coding skill expanded to C++, Python, and MATLAB for various projects.
CONTROLS
Classical, Modern and Optimal
The theoretical underpinnings in classical, Modern and Optimal Control are fortified with my work at BAJAJ tuning the throttle control, dealing with system inaccuracies, developing and testing control algorithms. Also, implemented Model Predictive control for various projects at CU-ICAR.
SYSTEMS INTEGRATION
Worked in Cross functional teams
The systems approach to learning and working was introduced to me at undergraduate Formula Student team and was further refined at Deep Orange where I led the Autonomous Driving Team and integrated with other teams like Human Machine Interface, Powertrain, Vehicle Dynamics. The know-how of how to thrive in a team environment, and the influence of communication.
