Need an idea for automatic self-levelling..!

[Greatbuddy]

Dear buddies,
I need an idea or directly any circuit which the circuit can automatically self level it position in X and Y direction..

I have a laser transmitter which i must calibrate it to ground level such that the beam must go and hit the reciever with out any deviation..

Let me know if further classification needed,,

Regards.

Self Leveling Range : may be ± 4 º

You have to invent a new kind of beam

 

[Greatbuddy]

New beam??

Beam will be the same, I think u havent get my point. I will attach a note for u all. Just click the link below..

Self levelling image.. and Datasheet..

Check the datasheets and and image too.

IIRC this is the third time you have posted the same question, didn't any of the previous replies help you at all.!

 

[Greatbuddy]

i have given round mark for that..

 

[Greatbuddy]

Previous replies helped me most. But its the different question not deals with the same ERIC..

If u have any idea then suggest me now. But i havent asked the same question in all my previous replies. Check my posts if u want if i have posted this type of thread then u can delete right now.. ok

hi GB,
I am always interested in laser type questions.

I need an idea or directly any circuit which the circuit can automatically self level it position in X and Y direction..

Do you mean the 'platform' has to be horizontal to the earths surface and remain that way even though the 'platforms' supports are moved.?

 

[Greatbuddy]

Yeah, u got my point ERIC,
The plaatform must be horizental referenced to ground level if its moved my natural calamities and it must adjust to that automatically buddy.

Do u have any suggestions for that.?

Eric,
Can u explain how did u catch that point from the post.

hi,
If the scanning laser is using a prism or mirror to deflect the transmitted beam from the vertical to the horizontal, then the standard way is to change the tilt of the prism/mirror rather than change the tilt of the complete laser head.

The prism/mirror having a small mass enables it to positioned by a small motor that controlled by a tilt sensor drive.

EDIT: note the amount you can level this way is +/- 3deg, refer your specifications.

hi rahulan,
I have been working with lasers for surveying since 1980, so I realised what GB was trying to say.

Can u explain how did u catch that point from the post.

 

[Greatbuddy]

Can u keep ur idea more brief in the form of any circuit Mr.Eric?

Iam really in need of it. Could u help me out?

 

[Greatbuddy]

Sorry, i cant get u ERIC if u give the scrap idea. I cannot catch that since iam not that much expert in this field but things could help me to learn me out more. Thanks once again.

hi,
The design of a automatic laser levelling system is quite complex and IMHO far to difficult to realise by using a forum.

These are some links showing some of the level sensor types available.
This first one is interesting, he has taken out sensors from a hand held wii controller.
