This is 4B's first 3d model prototype. The main parts consists from a base, 4 coxa linkages, 4 femuer linkages and 4 tibia linkages. The base and femuer linkages houses the HK-5320 micro servomotor.

Most of the robot's weight is positioned at the centre. This includes the battery, pcb and four out of the twelve servo motors. This low centre of gravity will give the robot more stability.

Thank you for your suggestion and cool project :) The 16340 looks a little big for this design as I only have a 25x25mm area space in the middle. I'm planning to use a 180/240mah lipo battery that also weight less than 6grams.

I wonder if putting a 16340 battery in the middle of the robot wouldn't work better in this case? I switched to those batteries for #SpiderWing and was quite happy with them. They have quite large capacity (but not nearly the 2500mAh that is advertised) and the shape of CR123A batteries. It seems like it could fit in the middle, and if not this, then other cyllindrical battery.
