For the front, I used an extension cube to mound a servo with a ping sensor, and I also have an IR sensor pointed down to prevent Roli from driving down the stairs attached to the bottom of hte servo (that is what the zip tie is for. None of the types of glue I have tried so far would hold the sensor to the bottom of the servo. You could use an extension block instead of or along with one or more extension cubes to add more front connectors.
i try al rotation servo's i had also the new ones but they always heat up,
even with new calibration,thats why i take a chorter arm.
your roli looks very technical,very neat build.
yes there chould be more female connector on the body roli.
The photo is in the resting position.
the heating starts by the first move they make.
so i move them forwarts and one less.if there where two slots more ,forwart.
that would be great.and some neat holes undernead to pull the wires thru.
something like this:
