EN2533 Robot Design and Competition module in third 🌟 My team and I navigated through a spectrum of challenges, showcasing our technical prowess and innovative solutions.

🏁 Task Highlights:

1. Line Following and Obstacle Avoidance: Our robot seamlessly maneuvered through a predefined path, effortlessly tackling twists and turns while avoiding obstacles.
2. Ramp Navigation & Box Dragging: Witness our robot's prowess as it conquered ramps and cleared paths by intelligently dragging a box, demonstrating adaptability and problem-solving skills.
3. Sound Detection Task: A cutting-edge feature enabled our robot to respond to sound cues, showcasing precision in halting its movements when needed.

🛠️ Fully Equipped Robot:

Our creation boasts an array of sensors and a touch screen interface for seamless control. The incorporation of advanced technologies has rendered our robot powerful, versatile, and ready for any challenge.

1. Sensors

• Aptinex Raykha S8 - Reflective Sensor Array: Utilized for line-following task with eight IR sensors for identifying line, junctions, and checkpoints.
• ST GY-VL53L0XV2 Time of-Flight Distance Sensor: Seven sensors employed for wall-following task and guard robot detection.
• 48 CPR Encoder: Regulates motor's RPM for accurate distance measurement on the ramp.
• TCS34725 RGB Color Recognition Sensor: Used for identifying red or blue color for subtask 4.
• Uxcell Sound Microphone Sensor Detection Module: Incorporated for sound detection in subtask 5.

2. Actuators

• 9.7:1 Metal Gearmotor 25Dx63L mm HP 12V with 48 CPR Encoder
• Continuous Rotation SG90 Servo Motor Plastic Wheel Full Set Normal (360 degrees)
• Standard 6 Volt with Metal Gear Servo Motor - 13kg (CAT.NO: YM2763)

CAD Design of the Robot Arm

• The robot arm consists of a gripper, distance sensor, and color sensor, controlled by two servo motors.
• Gripper operated by metal geared servo motor; larger servo motor controls arm's vertical movement.
• Distance and color sensors positioned at the gripper enhance the robot's capabilities.

3. Batteries

• 3300mAh LiPo

4. Other Components

• TFT Touch Sensitive Display: Integrated for selecting checkpoints.
• 25mm Castor Wheel
• DRV8256E Based Dual Motor Driver
• Buck Down Converter 5V
• Buck Down Converter 10V
• Battery Level Indicator

PCB Development

• Currently developing a shield PCB for Arduino board to minimize wires and simplify mechanism.
