I have built a 150 lb robot base and want to have a telescoping camera mount for filming football games . I would like it to be tall enough to view through the goal post
[...] and be retractable so it can change locations during the game.
I'm sure the goal post is 10' high at the crossbar. I would like to keep the base stack at about 4' in height
I will provide a link to my site below and you can view the robot base at its present state

I would like to keep the base stack at about 4' in height Haha, told you I'm not a football guy Apparently, I have no idea what part of a goal is the "post", whether it's translucent (which it'll have to be to film through it I guess), or what this crossbar might be. Measures like 10' and 4' are more "real" to me.Going from a collapsed less-than-4' to 10' shouldn't be that tough with a scissor lift, but the more "X"-es needed, the harder it is to get it smooth acting and stable at the same time, so the length of each link will matter. I wouldn't drive it around with a camera 10' up though, as it would probably sway some.Another thing to note is the vertical shift in the center of gravity - if you place something heavy up there, make sure it won't topple before mounting the camera.
Since his rig is 150lbs, the scissor lift crossbars could be 2 feet long
which then when cranked to an angle of 45 degrees would provide 2.8 feet of vertical height. If he added four more "Xs" then it would go up to 11 feet. This should be stable enough for the camera and probably no problem for the robot due to its weight. He could always add out-riggers if necessary.
No offense taken but You think my motor controls are Rube Goldbergesque...
...anyway 28 in diameter so I can get through a doorway and in the living room as well as behind the goal post that big post looking thing at the end of the football field...

[...] but anyway 28 in diameter so I can get through a doorwayand in the living room as well as behind the goal post that big post looking thing at the end of the football field they have one at each end of the field most have a single post about 10' high with a horizontal pipe about 16' wide and 2 upright pipes pointing up about 10' on the outside of the horizontal pipe And sometimes the players of football kick through those uprights at various distances to score points I want my camera to be there in between those uprights.
I'm trying to get myself out of the box you guys are the reason for that I like the scissor lift seems to be proven for weight with full stabilizers how much weight can I lift to 11 feet with my 28" helmet?Tom
whats up Soeren
