In their words
Pishnam is an autonomous robot built for the RoboCupJunior Rescue Line challenge and engineered with minimal reliance on ready-made modules. Every electronic board was custom-designed in Altium Designer, and every structural and mechanical part was modelled from scratch in SolidWorks and produced by FDM 3D printing, covering the full path from design to fabrication. The control software is written in C++ for deterministic speed and reliability. The robot follows the line, detects intersections and the evacuation zone reflective silver using an array of 39 infrared sensor pairs in addition to 4 pairs that assist in detecting victims and obstacles, recognizes green intersection markers and the evacuation point colors with three APDS-9960 color sensors, measures wall clearance and obstacles with VL53L1X time-of-flight sensors, and maintains orientation with a CMPS14 inertial compass. Motion and rescue actions are driven by ten Dynamixel servo motors — six XC430 and four XL330 — coordinated by an ESP32-S3-WROOM-1 microcontroller, with all sensors and actuators integrated across ten team-designed circuit boards. What sets Pishnam apart is the depth of its custom integration: the mechanical, electronic, and software subsystems were each designed in-house and tuned together, yielding a compact, robust platform that performs reliably across the line-following, victim-rescue, and evacuation tasks.
