Origin Story

In Grade 6, I challenged my friend Sam that I'd build a robot that acts like him. I didn't know anything about robotics — but a challenge was a challenge. I loved watching robotics videos anyway, so I went to Thamel, bought the chassis of a 4WD robot, and built an obstacle-avoiding robot. It was basic, but people liked it. I loved it too.

Samrat Bot 2.0 is the better version of that. A palm-sized personality robot with multiple behavior modes — he chases people, runs away, bumps into walls, or avoids them. Depends on his mood. He's cute too.

Line following is also on the roadmap. The goal is to make him small enough to fit in your palm, or shaped like a big mouse.

How It Works

01

Mood Engine — The robot cycles through personality states: curious, shy, playful, sleepy.

02

Sensors — Ultrasonic distance sensor for obstacle detection + IR for line following.

03

Behavior Logic — Each mood state determines how the robot reacts to sensor input.

04

Movement — Two-micro metal gearmotors for quiet, responsive movement.
