Hi SHUBHAMIITR,

It depends upon the type of the object you are planning to grab. If you can collect the object using some other mechanism, for example magnets, then you can use a single motor for lifting but I guess using two motors would be better.

hi shashwat,,,,

i hav to pick up wooden blocks actually............

can;t it b done wid single motor......

i feel that u can use a single motor for both grabbing and lifting by using the hydraulic mechanism and by using th appropriate gears(ie)worm and spur gears...

i built a hammer mechanism in a robot and i want to know the connections to be given for the 6v relay...

how do i show the difference between the two unary operators(ie)++a,a++ using a c++ language program...?

Two are to the coil. They're interchangable. Apply and remove power across these to switch the output.

One is output common. One is output normally-closed. One is output normally-open. When power is not applied to the coil, common is connected to normally-closed. When power is applied, common is connected to normally-open.

As far as which pin is which: The relay may have come with a small diagram labelling the pins, or the may be labels on the relay itself (often just a letter or two -- NC, NO, and so on), If not, you can figure it out with a bit of experimentation... or, if the case is transparent, you can often figure it out by inspection.
