Assembly Tutorials

Step-by-step guides for assembling common FTC robot components and subsystems.

Basic Chassis Assembly

  1. Cut or obtain aluminum extrusion for frame (typically 12"x12" base)
  2. Assemble frame using corner brackets and M4 bolts
  3. Attach motor mounts to frame using T-slot nuts
  4. Mount motors to frame with appropriate spacing
  5. Install wheels on motor shafts
  6. Add bearing blocks for wheel support
  7. Connect motors to Control Hub with cables

Linear Slide Assembly

Materials: REV Linear Slides, aluminum frame, motor, lead screw

  1. Assemble slide rails according to REV instructions
  2. Attach motor to carriage using motor bracket
  3. Connect motor output to lead screw
  4. Mount rails to robot chassis using L-brackets
  5. Apply lubricant to slide rails and lead screw
  6. Test smooth motion before final assembly

Servo-Driven Mechanism

Example: Claw Mechanism

  1. Design or 3D print claw arms
  2. Attach servo to robot frame using servo bracket
  3. Connect servo arms to claw linkages
  4. Test range of motion (0-180 degrees)
  5. Adjust servo zero position as needed
  6. Connect servo cable to Control Hub port
  7. Verify smooth operation without binding

Sensor Installation

Color Sensor

Mount on robot facing downward to detect field elements or elements on ground.

Distance Sensor

Mount on front or sides for obstacle detection. Ensure clear line-of-sight to target.

Camera

Mount on front with clear view. Secure cables to prevent accidental disconnection.

IMU

Mount on robot body (Control Hub location). Ensure not subject to vibration.

Electrical Assembly

  1. Connect battery to power switch using XT30 connectors
  2. Connect power switch output to Control Hub
  3. Connect motors to motor ports (matching software configuration)
  4. Connect servos to servo ports
  5. Connect sensors to I2C/analog ports
  6. Route cables through cable management
  7. Label all connections for easy troubleshooting
  8. Test power delivery to all components

Assembly Best Practices

  • Always use lock washers on critical fasteners
  • Don't over-tighten bolts (strip aluminum easily)
  • Leave room for future modifications
  • Label components and cables during assembly
  • Test each subsystem before full integration
  • Keep spare fasteners and components
  • Document your assembly process with photos
  • Perform load testing before competition

Common Assembly Mistakes

  • Misaligning wheels causing uneven traction
  • Loose connections leading to dropped motors
  • Forgetting cable strain relief
  • Over-tightening fasteners and cracking components
  • Poor cable routing causing tangles
  • Inadequate support for heavy mechanisms
