Robotics – Motors & Mechanical Assembly

Objective: Assemble the physical “body” of the robot and understand the mechanics of motion.

Presentation:

SC_3_Auto Directional Robot by Infinite Engineers

1. Understanding the “Muscles”: BO Motors

The BO (Battery Operated) Motors are the primary actuators for your robot.

  • Gearbox: These motors have internal gears that reduce speed but increase torque (turning force), allowing the robot to carry the weight of the batteries and electronics.
  • RPM (Revolutions Per Minute): Your kit uses 150 RPM motors, which provide a good balance between speed and control.
  • Soldering: Ensure the wires are securely soldered to the motor terminals before mounting to prevent loose connections during movement.

2. Mechanical Components Identification

Before assembly, identify these structural parts from your materials list:

  • Acrylic Chassis: The 2-layer frame that holds everything together.
  • Castor Wheel: The “third wheel” that provides 360-degree balance.
  • Wheels (65mm): The high-grip rubber wheels that fit onto the motor shafts.
  • Spacers (50mm & 30mm): Used to create the “second floor” for the ESP32 and sensors.

3. Step-by-Step Mechanical Assembly

Step A: Motor Mounting

  1. Align the BO Motors with the slots on the bottom layer of the acrylic chassis.
  2. Use the Motor Brackets and 3x30mm Bolts to sandwich the motor against the chassis.
  3. Secure them firmly with 3mm Nuts.

Step B: The Support System

  1. Attach the Castor Wheel to the front of the bottom plate using 3x10mm Bolts.
  2. Slide the 65mm Wheels onto the white shafts of the BO motors.

Step C: Creating the Second Layer

  1. Screw the 50mm or 30mm Spacers into the four corners of the bottom plate.
  2. Place the top layer of the chassis over the spacers and secure it with the remaining bolts.

Learning Outcome

By the end of this session, students will have built a sturdy, rolling mechanical base. They will understand how mechanical parts (bolts, spacers, chassis) and motors work together to form a robot’s physical structure.
