Project Overview

SLTC LETHALBOTS 2025 is the premier robotics battle competition in Sri Lanka, bringing together the brightest minds to compete, learn, and innovate.

About the Competition
SLTC LETHALBOTS 2025 is a dynamic robot battle competition organized by the undergraduates of Sri Lanka Technological Campus (SLTC). Students from all universities across the nation participate in this event which emerged from the shared enthusiasm for innovation and technology with the goal of motivating engineering and robotics interests.
Our Mission
For the lack of hands-on tech engagement among undergraduates, LETHALBOTS 2025 serves as our project to enhance robot design and building experiences through an impressive platform which helps students participate in robot battles for exciting technological innovation.
What to Expect
LETHALBOTS 2025 offers its participants more than competition because it embraces engineering excellence with team spirit through a celebration of Sri Lankan robotic advancement.
