  • Page 12: Remote Control Setup

    Remote Control Setup Your TETRIX PRIME robot is controlled by a standard 2.4 GHz remote controller and an accompanying receiver mounted to the robot. Transmitters are connected to specific receivers, allowing multiple transceiver combinations to be used in the same area.

  • Page 13: Continuous Run Servo Assembly

    Continuous Run Servo Assembly In order to facilitate ease of construction, the servo motors require preassembly. Locate the continuous run servo kit, which can be identified using the label attached to the servo. You will need the continuous run servo with screw, the servo mount with screws, a servo shaft hub, and a setscrew. You will also need Phillips-head and socket-head screwdrivers.
  • Page 14 Step 1 Step 2 Step 3...

  • Page 15: Standard Servo Assembly

    Standard Servo Assembly Locate the standard servo kit, which can be identified using the label attached to the servo. You will need the standard servo with screw, the servo mount with screws, a servo shaft hub, and a setscrew. You will also need Phillips-head and socket-head screwdrivers. Assemble the standard servo as indicated in the illustrations.
  • Page 16 Step 1 Step 2 Before attaching the servo hub, you must make Step 3 sure the server is in the neutral position. To do this, connect both the servo and the battery to the receiver and turn on the power to the remote transmitter.
  • Page 17 Step 4 Step 5 Step 6 Using the remote transmitter, verify the operation of the servo. If the servo operates properly, disconnect the battery from the receiver and the servo. Your servos are ready for use.

  • Page 18: Gripper Assembly

    Gripper Assembly Locate the gripper assembly parts bag. The gripper assembly must be assembled and properly adjusted to function. This part should not be disassembled by students in the normal operation in this activity. Use the four longer screws to attach the servo to the gripper plate. Use only the shorter, self-tapping screws included in the gripper assembly package.
  • Page 19 Step 5 Step 6 Align the left and right gripper gear arms to be parallel, align the gears to mesh, and place the gear onto the pivot. Install the washer and screw to hold the left gear in place. Before continuing the assembly process, remove the power from the servo.
  • Page 20 Step 11 Step 12 Step 13 Step 14 Step 15 Step 16...
  • Page 21 Step 17 Step 18 After completing the assembly, verify the operation of the gripper. Connect the servo to a battery and receiver and operate the controller to fully open and close the pincers. The pincers should move parallel to each other and close completely. If necessary, adjust the position of the gripper gear arms for correct operation.

  • Page 22: Construction Tips

    Construction Tips Connectors fit inside beams and come in straight, 90-degree, tee, and corner designs.
  • Page 23 Quick rivets and pegs are a quick option to use when securing connectors. Press the rivet in place on the beam and use the peg to spread the rivet to secure the connection. Using quick rivets on two sides of the connection will make it more stable.
  • Page 24 Joints can be made more permanent by using a thumbscrew and wing nut to secure the beams and connectors.
  • Page 25 Brackets can also be used to connect beams. Brackets are available for a tee connection, 60-degree connection, or 90-degree connection. Brackets should be used in pairs, with two brackets on opposite sides of a beam. Brackets are secured using quick rivets and pegs or thumbscrews and wing nuts.
  • Page 26 End connectors, straight, and 90-degree cross block connectors are secured using a thumbscrew through the beam and into the connector.
  • Page 27 After the thumbscrew is used to secure the end of the connector, a quick rivet and peg or a thumbscrew and wing nut are used to secure the intersecting beam.
  • Page 28 Anytime an axle is used, it should be supported at two points. Place a bronze bushing on opposite sides of a beam and place the axle through the bushings. Secure the axle to a stop collar, wheel, gear, or hub.
