Title: Locking mechanism
Post by: prashant on January 24, 2011, 11:14:46 AM
Hi ,
 Can any anyone suggest a mechanism to lock two bots together while on the move and work as a unison and also to disengage as per will??
 No restriction on size !!!

make them large enough to have their own gravity (think planet sized) and then put huge rocket boosters on them to separate at will.


Just kidding. =) Have you looked at something as simple as a trailer hitch? Just get a ball and cuff and put a servo on the little flip piece to lock the ball in. Loop and hook? How about putting a large screw on the end of a motor shaft and a nut on the other robot? Electro magnets? Permanent magnets with an ejection piston?

What kind of hold strength do they need? Does a com bus need to be established over this physical link or will it communicate wirelessly all the time? Will they always be on flat terrain, will there be obstacles?

you can use a servo that turns a twisted aluminum bracket into a slot of the other robot...
another one could be electromagnets,
then there are also this way that you can kind of build a housing for robot into the other robot, and first robot can reside inside the cavity and move out at the right point etc. ;D
