Portrait of Ashwin Narayan

Hello, I am Ashwin! I am a roboticist, amateur photographer and writer based in Singapore. I work as a Research Fellow in the Biorobotics Lab at NUS, building and testing rehabilitation and industrial exoskeletons. My expertise spans exoskeleton control, machine learning, biomechanics, and embedded systems. I graduated with a PhD in Biomedical Engineering from the National University of Singapore during which I worked on control of lower limb rehabilitation exoskeletons.

I like to take photographs in my spare time. I lean towards sunlit landscapes and interesting architecture and have a special interest in film photography. I am also an aspiring science fiction writer. Having been inspired by science fiction writers like Isaac Asimov and Arthur C. Clarke, I feel that the world needs more positive, inspiring stories that lay out a vision of where technology can take humanity.

On Coffee

A few words on what coffee means to me. It's more than just a beverage.

By Ashwin Narayan ·

It was 2016, my first year as a PhD student, and I was sitting in my corner of the lab. The post-lunch haze was starting to set in, and it was about the time I'd usually reach for a sachet of freeze-dried instant coffee from the stash in the rolling drawer cabinet under my desk.

Not today, though. My friend had just returned from his holiday in Vietnam with a small bag of dark, chocolatey Vietnamese coffee powder, and a little aluminum Phin filter. We extracted an inky, astringent brew on our first attempt, and I vaguely remember us talking about buying condensed milk so we could drink it the way the Vietnamese do.

After that, my coffee never came out of a sachet again (except for emergencies). That first cup set me off on a quest through most of the usual suspects (a French press, a Moka pot, an Aeropress, a Chemex) before I finally found stability in a modest Japanese brewer: the Hario V60.

Around the Hario v60, I built routines that have stuck with me through the better part of the last decade. Even today, nearly every morning, I prepare a light breakfast, brew a pour-over from fresh, hand-ground beans before sitting down at my table to reflect on, write about and plan out the rest of my day. This routine played an essential part in keeping me sane during chaotic times, especially during a year half of on and off lockdowns and other restrictions caused by the global pandemic. To me, coffee is a small island of peace — a few moments of calm thought before I head out into the chaos that is the world outside.

But that's not all of it. As anyone who drinks it regularly knows, coffee isn't only a solitary ritual. Many of the best conversations I've had at work happened not in meetings but over a steaming cup. The humble Phin filter kickstarted one friendship; my daily post-lunch brew has started many more, and more than a few research ideas began their journey mid-sip.

I still have the Phin filter lying around somewhere. I don't use it anymore, but I can't forget the journey it started. Over the years, my post-lunch coffee has gathered many people around it. I still share a brew with some of them from time to time. Some them of them are far away now. Colleagues may come and colleagues may go, but the coffee goes on forever.

These days, I brew two cups in the morning instead of one: one for me and one for my wife. I find myself looking forward to the brews I'll share in the next decade.

The Rest of the Face

Watercolour ·

Earlier this year, my wife and I traveled to Penang where we visited the Peranakan Mansion. It was beautiful, and we bought a notebook with a charming cover design at the gift shop there. I was practicing my watercolor skills at the time, and the cover caught my eye. I wondered what the rest of the face looked like, so I tried to paint it.

Probably one of my better works in watercolor. I'm still new to the medium, and it's tricky to work with, but I really like the delicate colors and soft, fuzzy edges it lends itself to.

My Attempt at Following a Bob Ross Tutorial

By Ashwin Narayan ·

So after getting my new iPad, I tried to work through one of Bob Ross’s videos as soon as I could. Here’s my attempt at the one from season 14 episode 1.

In the spirit of Bob’s technique, I tried making up stories about the things in my painting.

In the picture

  1. 1. The boat. The empty boat was used by a traveler to cross the water body. But he didn’t secure it well enough. Now he has to walk for several hours to get home.

  2. 2. The sky diver. The sky diver opened his parachute too late (he did not account for the mountain’s elevation) and will probably crash into the mountain too fast. Hopefully, the snow will cushion his fall.

  3. 3. The hiker. There’s a lone hiker on the mountain. He misjudged the slope. Shortly after the moment captured by the painting, he slips and slides all the way down. Let’s hope he’s able to call for help using his radio.

  4. 4. The mountain goat. The mountain goat is enjoying the fabulous day.

  5. 5. The SR-71. An SR-71 Blackbird is flying by at greater than Mach 3. Its sonic boom might trigger a minor avalanche.
