Ghost Rider – Halloween Omni Wheel Robot. Advanced classes

Ghost Rider is a Halloween robotics project for students aged 11+. In this project, students build and program a Bluetooth-controlled robotic car that carries a small electric ghost candle. The robot uses three omni wheels, allowing it to move forward, backward, rotate, and slide sideways in a way that ordinary wheeled robots cannot.

Students program the robot using the Arduino IDE and Arduino C, giving them direct control over the robot's motors and movement logic. They learn how to define motor pins, write movement functions, control motor direction, and structure their code so the robot can respond to wireless commands from a Bluetooth ring controller.

The robot is built around an ESP32 microcontroller, three DC motors, and motor driver modules. Students explore how a microcontroller sends digital and PWM signals to motor drivers, and how these signals are converted into real movement. They also learn why motor direction, wheel placement, and speed balancing are important for creating smooth omni-wheel motion.

The Bluetooth ring controller makes the project interactive and practical. Students write code that receives wireless commands and translates them into robot behaviour, such as moving forward, reversing, turning, stopping, or sliding sideways. This helps them understand how embedded software connects user input with physical hardware.

For the Halloween theme, the finished robot carries a small plastic electric candle with a ghost face, turning the project into a moving ghost light. The creative theme makes the project fun, while the engineering behind it remains real and technically meaningful.

During the project, students practise circuit building, motor testing, debugging, code organisation, and movement calibration. They learn that a robot rarely works perfectly on the first try, and that good engineering means testing each subsystem, finding mistakes, and improving both the wiring and the software.

By the end of the project, each student will have built and programmed a working Bluetooth-controlled Ghost Rider robot and will understand the core principles of DC motor control, wireless communication, embedded programming, and omni-wheel movement.

By building and programming their own Halloween-themed Ghost Rider robot, students see how electronics, mechanics, wireless communication, and embedded software work together in a complete robotics project.

Over a series of lessons, students will:

• Understand how omni-wheel robots move
• Program a robot using Arduino C
• Control DC motors with motor drivers
• Use PWM to control motor speed
• Build a complete embedded robotics system
• Learn how Bluetooth commands control hardware
• Develop modular movement code
• Debug motor direction and movement behaviour
• Develop engineering and problem-solving skills
• Gain confidence with real robotics hardware
