How to be an autonomous car engineer in India

If you look at the automobile industry it is evident that self-driving technology is cruising into India. But are we on-board?

Self-driving vehicles have been a topic of contention in the world of technology for quite some time now. While the general sentiment in the automotive industry is that autonomous cars are ready to roll into our driveways any moment now, in all their driverless glory, if reports are to be believed then truly autonomous vehicles are quite far away. Given that most people expect the industry to take a few decades to mature, acting now could get you in on the ground floor of an industry that’s sure to skyrocket. After all, people like Elon Musk know a lot more about it than us. But where do you start?

How it comes together

Autonomous vehicles are fairly complicated systems, especially from an academic point of view, with a multitude of areas working together. Even in the industry, the main focus is on developing a problem statement that encompasses all these areas effectively – as in, the biggest question is, how to make all these systems work together effectively and seamlessly to make a flawless autonomous driving system.

For instance, the broadest field that covers most of the areas involved in autonomous driving is mobile robotics. However, there’s also a huge role for mathematics. According to Ankur Pandey, Sr. Data Scientist, HERE Solutions India Pvt. Ltd., “Deep Learning (and Machine Learning in general), Computer Vision/ Image Processing, Sensors, Robotics, IoT, Embedded systems, are the hot skill sets for breaking into self-driving car/vehicle industry. One must (also) have excellent program chops (specifically Python, and C++).”

Even in their initial stages, perfectly autonomous vehicles can transform what it means to drive

Anyone working with autonomous vehicles has to deal with three different modules – a module to accept sensory input, another to calculate the correct outputs, which are sent to a third module – that acts on it to provide accurate guidance to the vehicle. The sensory input module would involve dealing with mechanical, visual, and digital sensors that locate the vehicle, study the surrounding terrain and objects, and pass this information on. The processing module then leverages neural networks to process this information to decide courses of action – accelerating, braking, or turning. The third module uses these decisions as an input, and convert them into mechanical actions upon the physical body of the car to translate them into the actual driving of the car.

Skills needed

According to Ishan Gupta, MD-India, Udacity, the skills that the industry is looking for are:

  • Python and C++
  • TensorFlow
  • Keras
  • OpenCV
  • NumPy
  • Scikit-leam
  • Amazon Web Services
  • Anaconda
  • make.
Udacity’s Self Driving Car Nanodegree is a comprehensive course to prepare yourself
for a career in this industry

Apart from this, familiarity with neural networks, image processing, sensory calibration, object detection and virtual filters, prediction and measurement loops, open and closed- loop controllers, data calibration and fusion, as well as linear quadratic regulators are also skills that make one a better candidate.

Robot OS (ROS)

A good place to start, according to Rajesh Kumar, VP, Strategic initiatives at Tata Elxsi, is the Robot Operating System (ROS). Technically, it is a collection of frameworks for the development of robot software, but it also provides services designed for a heterogeneous computer cluster such as hardware abstraction, low-level device control, message-passing between processes, and package management, making it almost a full-fledged operating system.

ROS: The Linux for Robotics

There are quite a few milestones that ROS has achieved in the autonomous vehicle industry. For instance, Baidu’s open sourced autonomous vehicle platform, Apollo, runs entirely on ROS, and BMW, Bosch, and the recent Delphi-acquired NuTonomy also use it.

Advantages of using ROS include:

  • A lot of code is available
    Algorithms with all the capabilities required for the navigation of wheeled robots have already been created in ROS and self-driving cars can just make use of them.
  • Visualization tools present
    A suite of graphical tools for easy recording and visualization of sensor data to represent the status of the vehicle are already available in ROS.
  • It is relatively simple
    You can start right now with a simple robot equipped with a pair of wheels, a camera, a laser scanner, and the ROS navigation stack, and you will be learning in a few hours tops.

You can download the ROS framework at ros.org, learn basic and advanced concepts at http://dgit.in/RIAROS. Also, check out Turtlesim (http://dgit.in/TurtleSim) which is a tool made for teaching ROS.

Opportunities

You might think India doesn’t have a market for self-driving vehicle technologies, and you’d be partially right. After all, the driving conditions in India are far from predictable.

“We are pretty far from making cars fit to drive in everyday Indian traffic conditions.” says Mr Ankur Pandey, “To progress in this industry we need to design increasingly smarter algorithms (AI), but we also need innovation in sensors/hardware components. Then there’s another angle, which might be to develop 3D maps with ultra-high precision and almost real-time updates, which can be used by a vehicle connected to the cloud. It’s what we’re aiming at achieving at HERE Technologies.”

HERE Solutions is working on an HD Live map that ‘self-heals’ in real time

Autonomous vehicles actually perform better when there are more autonomous vehicles in operation. They’re able to communicate and learn from one another. Of course, we need the required infrastructure and policies, which is something that the Government of India is still working on.

Is it worth it?

Companies like Hi-Tech Robotics and NXP Technologies are investing time and effort to make this a more mature field in India, and at the same time, bringing the workforce to a standard skill level. “Majority of companies are picking up the pace with autonomous vehicle technology and adopting processes that are aligned to the technological evolution,” says Ritukar Vijay, Head of Technology and Strategy, Hi-Tech Robotics, “We at Hi-Tech Robotic Systemz lay huge emphasis on the core knowledge of artificial intelligence and autonomous navigation technology. We aim to provide young aspirants with practical experience in the field of AI and advanced autonomous technology. We happen to work with one of the leaders in self-driving courses online – Udacity.”

CSIRO ICT Centre has trialled its automation technology in large Hot Metal Carriers (HMC), capable of delivering buckets of molten aluminium without human intervention, at Rio Tinto Aluminium’s Bell Bay Smelter in Tasmania.

It’s not just road vehicles that can be autonomous. Industrial logistics, navigating hazardous environments and even military vehicles are perfect use cases that are being worked on by startups and big corporations alike, and there’s big money and a lucrative career in those fields. Now, it is up to you whether you want to board the driverless bus to the future or stick with tried and tested fields. Either way – here’s wishing you a safe (and hands-free) journey.
