Low Rider Otto Hp Module + ORIGINAL MODEL

                                       :english version:

This extension transforms your Otto HP robot into a Low Rider with articulated suspension.

• It uses 8 servo motors:

  • 4 servos for the wheels, inserted into the side holes of the chassis.

  • 4 servos for the articulated arms, allowing the robot to lower or raise its body.

• The arms create a mechanical articulation:

  • Each arm is mounted on a servo, enabling dynamic movement and lowering the robot until its underside touches the ground.

  • This gives the robot a true “low rider” stance.

• Parts to 3D print:

• 4× arm

• 2× arm support

Once assembled, the robot can squat, tilt, or lie flat — perfect for expressive movement or terrain adaptation.

        :how to assemble:

1 — Prepare all the parts you need

Make sure you have everything ready before starting:

• 8× micro servos

• 4× M2.0 screws (for securing the arm supports)

• The already‑assembled Otto HP body

• 4× Arm pieces (3D printed)

• 2× Arm Support pieces (3D printed)

2 — Flip the body upside down

Turn the Otto HP body so the underside is facing up.
This gives you access to all the servo mounting holes.

3 — Insert the arm supports into the arm pieces

• Slide each Arm Support into its matching Arm.

• Make sure the fit is tight and aligned.

• These will hold the servos in place later.

4 — Insert the servos into the designed holes

• Place one servo into each hole designed for it on the body.

• Make sure the servo shaft is oriented correctly.

• Push the servos fully into the openings.

5 — Screw the servos in place

• Use the M2.0 screws to secure the servos.

• Tightening the servos will also lock the Arm Supports firmly in position.

• Ensure everything is stable and aligned.

6 — Attach the full assembly to the Otto HP body

• Once the servos and supports are installed, place the entire assembly onto the Otto HP body.

• Press gently until everything fits into place.
