Ive done a four bar lifter in 50mm. Almost anything can be done, youve just got to work out how to do it

25cm is a little on the small side, maybe up 80-100mm

was your bot still invertable with the 4 bar? and was it powerful enough to turn other 12kg bots with ease?

Yes. Yes (well the arrangement of the bars was more refined for lifting as opposed to turning over - calculating the geometry of the four bar lifter you want is a fine art).

ewan what dia are your drill motors? with 75 mm wheels i would only have 49 to 53 mm inside the armor depending on material thikness. what did u use to build the 4 bar?

I would kill to make a 4 bar system , but alas it seems to complicated for me , lol

The stripped body of drills will easily fit into a 50mm body height (stripped diameter being slightly less, though dont have specifics off the top of my head). Its just a case of finding mounts suitable for such an inner body height.

I used a load of aluminum, some iron angle, a hacksaw, jigsaw, pillar drill and file.

well if u only got a low profile bot its gunna make all weaponary harder to design.
remember that test frame i put this flipper in? it was only running at 60psi thats like what ? 4 bar or sumthing i dunno i suck at this stuff.

well i ordered some motor mounts from james baker hes helped me out alot understanding stuff and how stuffs worked out.

edit: think polycarb sides on frame would work for a 4 bar ?

was it the action bot that will has now that had the 4 bar in?
if i was to go with this do you still know what the specs of the 4 bar was?

Tom, might I make a suggestion?

Put all of your questions down on a piece of paper and put one or two posts on the forum each day. It becomes difficult to follow what you are asking and difficult to answer your questions.

Got nearly everything ordered now i just need stuff from ewan and sum sort of a pneumatic system.
anyone got any old pneumatic stuff or know where theres sum going cheap?
then i just have to think of a chassis/body design and what to build it from.
