A 3D printer creates objects by precisely depositing melted plastic or other materials in thin layers until the final shape is formed. The process begins with a 3D model from CAD software, converted into G-code instructions. Widely used in engineering, education, product design, and medical fields for rapid prototyping.

Equipped with sensors and GPS, this drone performs tasks like surveillance or delivery, then autonomously returns to a custom charging station. The station uses landing detection and charging contacts for hands-off recharging, combining flight control, automation, and power management.

Inspired by Greek mythology, this table uses stepper motors and magnets controlled by a microcontroller to move a metal ball that creates evolving sand designs. Blends engineering and art into an automated kinetic sculpture.

This UAV performs autonomous navigation, environmental monitoring, payload delivery, and data collection using GPS and onboard sensors. Suitable for agriculture, disaster response, and surveillance with programmable route following or real-time adaptation.

Uses IR sensors to detect a line (typically black on white) and follows it via microcontroller commands to DC motors. Components include Arduino, L298N motor driver, and IR sensors. Demonstrates basic robotics and sensor integration.

Uses ultrasonic sensors (HC-SR04) to detect objects and an Arduino to control motors for collision avoidance. The sensor measures sound wave reflection time to determine distance, triggering evasive maneuvers.

Uses ultrasonic sensors or cameras to maintain a fixed distance from a human. The microcontroller processes sensor data to adjust movement via motors, enabling persistent tracking for applications like luggage carriers.

Remote-controlled robot with high-torque motors and weapons (e.g., blades, lifters) for competitions. Features durable metal chassis and emphasizes mechanical design, control systems, and safety in adversarial scenarios.

Lightweight foam/balsa plane with electric motor and servo-controlled surfaces (rudder, elevator, ailerons). Teaches aerodynamics and radio communication, usable for hobby flying or as an automation platform.

Uses IR/camera sensors to track a ball, navigate the field, and kick toward a goal. Combines computer vision, motor control, and strategy for dynamic competition environments.

Glides on an air cushion created by lift fans, enabling movement over land/water. Demonstrates fluid dynamics and unconventional locomotion using thrust motors/rudders for control.

Interconnected triangle design distributes loads efficiently in bridges, towers, or robotic arms. Teaches physics and mechanical design principles for stress-resistant structures.
