This kit equips you with front-facing TCRT5000 IR sensors to lock onto an adversary and rear sensors to detect the white perimeter line, mimicking real competition behavior. Whether you're preparing for a school tech fest or tinkering at home, you'll have a robot that reacts, retreats, and charges again entirely on its own.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou assemble a compact robot on a sturdy chassis, powered by dual TT gear motors and controlled by an Arduino Uno R3. Four TCRT5000 IR modules do the heavy lifting - two in the nose to spot opponents and two at the tail to constantly monitor the ring edge. When the front sensors trigger, the robot lunges forward; the moment a rear sensor sees the white boundary, the robot immediately reverses, spins, and resumes its hunt. By the end, you have a mini sumo contender that understands its environment without a single line of remote control code.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCalibrate TCRT5000 IR sensors to distinguish between a dark sumo ring surface and a white boundary line\u003c\/li\u003e\n  \u003cli\u003eInterface an L298N motor driver with Arduino to control bidirectional motion of two DC gear motors\u003c\/li\u003e\n  \u003cli\u003eWrite decision logic that switches between search, attack, and edge-avoidance behaviors in milliseconds\u003c\/li\u003e\n  \u003cli\u003eTroubleshoot sensor noise and power distribution - skills directly transferable to line followers and maze solvers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTCRT5000 IR Module\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eL298N Motor Driver\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTT Gear Motor\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2WD Chassis\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e18650 Cell\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e18650 Holder\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
