Many of MIRO's user-serviceable parts are under the body shell, being the large white plastic part covering the main body. This page documents how to remove the shell to gain access to these parts.
Body shell release
In order to remove MIRO's body shell, the head needs to be in the down position, i.e. with the neck member at the front end of the neck slot. MIRO has a special mode called "shell release" mode in which the head is moved to this position. There are two ways to engage this mode, described below—choose one or the other.
Turn MIRO upside-down, supporting him between your thighs, as shown above. Switch MIRO on. After a few seconds, shell release mode will engage and the head will move slowly to the down position. Switch MIRO off before proceeding.
(2) Palm touch
With MIRO the right way up, switch on. Immediately after this, place the whole palm of your hand across MIRO's back, as shown above, to contact all four touch sensors. Hold this position for a few seconds until shell release mode is engaged, and the head will move to the down position. Switch MIRO off before proceeding.
Turn MIRO upside-down, supporting him between your thighs, as shown above. There are six screws on MIRO's underside securing the body shell. They can easily be confused with the neighbouring screws which hold MIRO's base together. The body shell securing screws are marked red in the image—remove only these six screws.
Now, being careful to support the body shell which is now detached from MIRO, turn MIRO back the right way up. You can now withdraw the shell carefully, lifting the rear edge first and then sliding the front edge up and back so that the neck slot clears the neck member. Release the shell from the flexible slot cover that fits into the channel on the underside of the body shell. Finally, unplug the connector for the body shell touch sensors from its socket at UC1:J3, noting its location for refitting.
Refitting is the reverse of removal, but note the following points before you start.
Then, proceed as follows:
- Reconnect the body shell touch sensor board to UC1:J3, as shown in the image to the right.
- Engage the flexible slot cover with the channel in the underside of the body shell.
- Engage the neck slot in the body shell with the neck member.
- Starting at the front edge, refit the body shell, using firm but careful pressure to mate all six pillars (this step requires a little imagination, but becomes easier with practice).
- Flip MIRO over, holding the shell in place, and reinsert the securing screws, massaging the shell as necessary to engage the screws.
