“INFO ABOUT A DEVICE!”

Can't really grasp your requirement...

But it sounds like a remotely controlled arm to me...V expensive or make your own.

Qs

Range of movement?

Load to be carried?

Positional accuracy/rigidity?

Does it need to grasp?

Does it need to bend or navigate around corners?

x y & z coordinates presumably?

Will the operator be able to observe the device e.g he will provide the feedback.

Does it have to be motorised or can it be 'mandraulic' (joke word for manual).

That's it! I'm sendin' in the dogs! you posted that whilst I was a typin' you scruffy rat catcher you!

Now I gotta put up with all the meatheads that are gonna encourage me "to read before I post" and I gotta go edit my text cuz I aint first anymore.

You are a bit vague as to the device's limiting factors as well as application, but I'll go first [or second, Del Gato].

Do you want to look inside? Do you want to measure distance, temp, surface finish, etc.? Are we dealing with a continuous diameter or does it reduce? Is the ID surface finish susceptible to scratching and/or contamination? Is it bigger than a breadbox? Can you tie a string to a camera and microphone laden gerbil?

How big a diameter are we talking here? 2.54cm is gonna be a very limiting factor. 39.03in not so much. A series of right turns. Are they 90 degrees?

Other limiting factors such as temp, atmosphere (gaseous, aqueous), kosher, etc.

Try a bore scope, fiber optic or video scope. Try fish tape. Try pipeline pig. Build your own.

I, too, think the post is quite vague. GERARD18, please be more specific as to what you are looking for.

Mr. Rummel, are you just teasing Del? You know how much he loves "fish tape".

Just teasing Del.

The medical profession has several device that some like it would do. The camera devices the use to explore with. They will bend with out side controls so that they can be pushed it to the proper branch junction of say an artery. The scope used to view the colon
