What is a Triopod ?A tripod is a portable three-legged frame, used as a platform for supporting the weight and maintaining the stability of some other object. A tripod provides stability against downward forces and horizontal forces and movements about horizontal axes. The positioning of the three feet away from the vertical center allows the tripod better leverage for resisting lateral forces.

Problem Statement / Aim :To Design a collapsible tripod kind of system, that can be positioned on the road side, and can go up to a height of about 20-25 feet, from where a camera can record the tra�c movement additional features a battery source at the bottom, ability to adjust the camera direction from below etc. and itis also useful other places also.

Objectives:1.To solve Problems related to tra�c signal security2.To record tra�c movement at tra�c junctions3.To record tra�c movement at 360 degree angle

User Questionaire :

User Response:

Analysis from Survey:Q1: Is Videography your hobby? As per analysis we can note that for half of the users videography is an hobby and there is chance of using a tripod while taking a video.

Q2: How often you go out for taking videos?

From the analysis we see that even though videography is not an hobby one would like to shoot a video according to his/ her needs so there is chance using a tripod to complete his/ her work

Analysis from Survey:Q3: Are you interested in doing �eld studies?

In this category there is a chance of �nding maximum number of users because most of the empolyees and students go out for �nd studies and they often use tripods for taking photos and recording videos

Q4: How often you travel in a week?Here most of the users travel depending on there work

Analysis from Survey:

Q5: Did you ever get struck in tra�c?Most of the users got struck in the tra�c at least once and their security is been put in to question. So to provide them a better security we need to have video recording system to keep track on the tra�c moment.

Q6: Is there a need for improvement in the security system at tra�c signal lights and shopping malls?

Most of the users say that there is a need to for improvement in the security system that is there in the croweded areas.

Dimensions of the Design:“H” pattern wooden legs were used to make tripod legs, because they o�er optimum rigidy, just like the steel beams used in construction. The lags of tripod has 40x25mm oak for the ‘|’ og the ‘H’ (40 for outer leg and 25 for the center extendable leg): again, precise measurements is not paramount, it just needs to be ‘wider’ than the center srtip. The wider the strip, the sti�er the tripod.The plastic extenable tripod head used has two circular section. Smaller ectenable circular section is about 12feet and can go up to height of 10 feet. The larger extendable circular section is about 14feets and can go upto 12 feet height. The extendable legs has length of 5feet which can be extendable up to 3 feet length and the legs are of normal height. The small section has the radius of 6cm and the bigger circle has radius of 8cm.The extendable tripod head is the most di�cult piece to make. The shape of the tray doesnot matter much it can be a triangle or a circle , as you like it. But the three outside pegs have to be at your best 1200 angle. They have to be close to the widht of the extendable legs as possible, again to for stability sake. There you have two options(�gure2): either you have board thick enough to drill through it, or you have a thin board, and place a thick piece of wood under to drive the bolt through it.
