Builder · Founder & CEO of Eka
14, in Grade 10, building robots and offline AI from Indore. Most of it works. The rest is being debugged.

(01) Hello
note: “serious” is relative. The robots still occasionally drive into walls.
I like problems you can hold: a robot that has to follow a line faster than the one in the next lane, a box that has to answer a question with the Wi-Fi switched off. I started in competition robotics and never really left. Somewhere along the way the projects got serious enough to need a company, so I started one. It’s called Eka, and it ships two products.

(03) The company
Eka (एक) — Sanskrit for “one”. One company, two products. Both designed, engineered and shipped by me.

Eka builds AI that works where you are — on your desk, in your bag, on your own computer — instead of somewhere far away on a server you’ll never see.
If it can run on the device, it runs on the device. The internet is an option, not a dependency.
Shortcuts, push-to-talk buttons and plain answers. Not dashboards.
From the 3D-printed case to the last keyboard shortcut, everything is designed and built in-house — which is to say, by the founder.
(04) Product 01 · by Eka
The study companion that never goes online.
Buddie is a small white box with a screen, a camera and a push-to-talk button. Ask it a question and it answers — with every byte of the thinking happening inside the box.
(05) Product 02 · by Eka
Command your PC. An AI pet for Windows.
Demo · scripted replies · nothing runs on your PC
Talk or type. Gullu opens apps, finds files and gets it done. Press Ctrl Alt Space from any app. It even works with the Wi-Fi off.
Gullu is a one-eyed egg with an antenna and a slightly judgemental stare. He calls you “boss”.

Team site: rudrax-nrl.in
Checkpoint · 2025
4 medals at the WSRO Nationals, then the World Finals in Dubai: 8th in the world.
Checkpoint · 2024
2nd place as team captain, plus more medals as a team member.
Checkpoint · Multi-year
Won across several seasons of the International Robotics Championship.

engineering note: downforce means it can take corners at speeds that would otherwise end in a wall.

(07) How anything here gets made
The unglamorous loop that makes everything on this page.
Start with the smallest thing that could possibly work. Usually a breadboard, a Python script, and too many jumper wires.
Run it until it breaks. Measure where. Write the number down, because “feels faster” is not a benchmark.
It fails. Of course it fails. The interesting part is finding out exactly why.
Change one thing. Repeat. Ship the version that survives.
(08) Contact
Collaborations, competitions, questions about Buddie or Gullu, or just to say the line-follower was cool — email is the fastest way to reach me. (I don’t have a phone line, so email it is.)
