In some instances, you may need to replace your robot's SD card. This article will walk you through the necessary steps.

Please note that there are separate instructions for the OT-2 and OT-2R within this article. Both robots follow similar workflows for replacing the SD card, but the location and arrangement of hardware is slightly different.

Instructions for the OT-2 are shown first, followed by the OT-2R.

If you are unsure which robot you are working with, please see our article that highlights the differences between the OT-2 and OT-2R before getting started.

Instructions for OT-2

Materials needed:

  • Allen key set provided with your robot (specifically, the 2.5mm hex driver)

  • Tweezers

  • New Micro SD card

  • Step stool (if your robot is placed on a tall bench)

Procedure:

1. Power off your robot and disconnect from any cables.

2. Turn your robot around so that you can access the back electronics enclosure panel.

3. Using your 2.5mm hex driver, remove the 4 screws which fasten the top acrylic panel and remove the panel by sliding and lifting.

4. Now with your 2.5mm hex driver, remove the following screws to loosen the electronics enclosure cover. Once you reach the last two screws, place your hand on the top of the robot to remove the casing.

5. With one hand, wedge the electronics enclosure open to access the Raspberry Pi (green circuit board on left) and notice the Micro SD card at the top.

6. With your other hand, take your tweezers and remove the Micro SD card.

Important: Notice the orientation of the SD card for when you replace it to ensure it is properly inserted.

7. Insert the new Micro SD card into the Raspberry Pi.

8. Re-fasten the electronics enclosure cover and top acrylic. Power on the robot and it should automatically home. You will now need to factory reset your robot’s deck.


Instructions for OT-2R

Materials needed:

  • T10 Torx (star) driver provided with your robot

  • Tweezers

  • New Micro SD card

  • Step stool (if your robot is placed on a tall bench)

Procedure:

1. Power off your robot and disconnect from any cables.

2. Turn your robot around so that you can access the back electronics enclosure panel.

3. Now with your T10 Torx driver, remove the four corner screws shown below to open up the electronics enclosure cover.

4. With the panel removed, you can now access the Raspberry Pi (green circuit board on left). Notice where the Micro SD card goes: It slides into the top of the Raspberry Pi.

Update: The gray grounding strap is now located in the upper right (previously upper left as shown in this image).

5. Take your tweezers and remove the Micro SD card.

Important: Notice the orientation of the SD card for when you replace it to ensure it is properly inserted.

Below shows a closer view of removing the SD card:

6. Note the orientation and insert the new Micro SD card into the Raspberry Pi.

Important: Before putting the metal panel back on, notice that the inside of the panel is partially unpainted. This is to establish a solid electrical connection from the panel to the gray grounding strap cable (located in the upper right within the enclosure). When putting the panel back on, it is important to ensure that the gray grounding strap cable is sandwiched between two pieces of metal when it is fastened.

7. Re-fasten the electronics enclosure while ensuring that the gray grounding strap cable is sandwiched between two pieces of metal. Power on the robot and it should automatically home. You will now need to factory reset your robot’s deck.
