Hi,
When you say mana cat - were you using the bionacle "manas" parts? Or
was it just a name? I had some fun trying to incorporate them into a
robot as extra powered motors for the RCX.
The joints are all posable with worm gears arent they? I had a thought
last night on a "compliant" worm gear based joint - which involved
fixing the gear onto an axle, and allowing a housing assembly around
the axle to move a little with a technic suspension - thus giving a
joint a little compliance, which still springs back to the desired
position when the force comes off. The alternative I had (which is a
great deal more "human") was to use elastic-band tendons, and then
have a set of two (or four using long pins) technic pulleys - either
side of 2 pins - so a contraction would mean reeling in (winding up)
the elastic band between the pulleys. The pulleys would probably be
best driven by a high reduction system with a worm gear, and maybe a
clutch to ensure that the thing stops before the band snaps. I may
design an arm - and later a whole mech based on that...
The prop housings - the yellow parts are most definately from the
yellow technic sub - I have a couple. I have seen them in red too.
Take a look here http://www.peeron.com/inv/parts/2745 - they are
available in grey from the X-Wing fighter.
Is the ball joint one of these : http://www.peeron.com/inv/parts/44359?
I think the socket on Mr Jeeves is http://www.peeron.com/inv/parts/44358.
I am always interested in socket/ball joints - and larger ones more
so. Maybe we will see more of these in the coming lego mech series.
Anyway - I think it looks good, thanks for posting them eric.
