Clawbot Build Instructions

Assembly Steps

Step 1: Chassis Assembly

Begin by constructing the base frame of the robot. Take two of the longer metal beams (e.g., 1x 276-6009-001 or similar). Attach two wheels to each side of these beams using the provided axles and nuts. Ensure the wheels are securely fastened but can still rotate freely. This forms the basic rolling chassis.

Step 2: Adding Structural Support

Attach shorter metal beams perpendicular to the main chassis beams to create a more rigid structure. Use 8-32 nuts and bolts (e.g., 30x 8-32 Nut and 30x 8-32 x 0.375 in) to connect these pieces. Refer to the diagrams for precise placement, ensuring a stable foundation for the rest of the robot.

Step 2a: Alternative Chassis Configuration

For an alternative chassis setup, connect two beams of equal length using cross-members. Secure these with 8-32 nuts and bolts. This configuration provides a different base for mounting components.

Step 3: Mounting the Control System

Attach the VEX V5 Control System (e.g., 1x 276-4810) to the chassis. Use appropriate mounting brackets or beams to secure it firmly in the center of the robot. Ensure all ports are accessible.

Step 4: Building the Claw Mechanism

Construct the claw assembly. This typically involves using gears (e.g., 1x 84T 276-3438-331, 1x 12T 276-6010-011, 1x 12T Pinion 276-2250-008) to create a gear train that will drive the claw's opening and closing motion. Mount the claw motor (often a V5 Smart Motor, e.g., 1x 276-4840) and connect it to the gear train. Attach the claw itself to the output shaft of the gear train.

Step 5: Attaching the Arm/Lift Mechanism

Assemble the arm that will hold the claw. This usually involves connecting several metal beams together to form a sturdy arm. Mount a motor (e.g., 1x 276-4840) to power the arm's lifting and lowering movement. Connect this motor to the arm structure, often using gears or direct drive.

Step 6: Connecting the Arm to the Chassis

Mount the completed arm assembly onto the robot's chassis. Ensure it is securely attached and can pivot or lift smoothly. Connect the arm motor to the V5 Control System using the provided smart cables (e.g., 1x 180 mm 276-4817-100, 3x 300 mm 276-4860-020, 1x 600 mm 276-4860-030, 1x 900 mm 276-4861-010).

Step 7: Connecting the Claw to the Arm

Attach the claw mechanism to the end of the arm. Connect the claw motor to the V5 Control System using another smart cable. Ensure the claw can move freely and is positioned correctly on the arm.

Step 8: Wiring and Final Checks

Connect all motors and sensors to the V5 Control System. Double-check all connections and ensure all parts are securely fastened. Verify that all components are correctly oriented and that there are no loose parts. The robot is now assembled and ready for programming.
