INTRO
The attachment of the two Y-frames (left, right), the central torso brace and the lower crank motor braces was shown in the previous page (4).
The items to attach here are located approximately where the arrow is indicating below.
When completed it will look like this:
PARTS
List of components presented in this page:
- Hip, left (#20)
- Hip, right (#21)
- Belly rod (#22)
- M3 socket screws, 20mm (x4)
- M3 socket screws, 12mm (x1)
- M4 nut (x2)
- M3 nuts (3)
- M3 washers (6)
- black cable ties (4)
Labelled exploded view below…
The new 3D printed parts are shown below:
The hips, left (20) & right (21) are attached to the lower crank assembly motor lugs with two 20mm M3 socket screws and washers (arrows below; Nb nuts should already be in the recessed cavities on the inside motor holders from a previous page).
Nb the lower screw and nut (yellow arrow above) on each side should not yet be fully tightened because further components needed to be added (see page 6).
Note that some cable ties have been used to tidy up the wires from the motors (4).
The belly rod (22) with M3 nuts embedded in the cavities (as shown further above) are attached with two M3 x 10mm socket screws plus a washer, to the two lugs at the front (red arrows below):
An M3 socket screw x 12mm with nut is used at the other end of the belly rod (green arrow below), but is not secured as other components are needed first (this actually does not get done until page 10, so you can tighten it to give the device more rigidity):
Note, the rear legs (see page 9) will attach to the upper lugs. On the reverse of the frontwards-facing one is a recess for an M4 nut (yellow arrow below):
Place an M4 nut in the recess (yellow arrow below) as there will not be space to add one later.
Next is to build up the ‘belly space-frame’ using components that connect from the motor holders to the belly rod. This will be done on page 6.
