In order to shoot a good tracking shot on your video camera, few things add more value to the shot. When camera is on wheels, and moves around, you will be able to shoot a quality picture.

It is possible to shoot movies with the help of a single lens reflex camera, and you require a single tiny dolly. CineSkates system is used in this case, but we heard something called Pico Flex Dolly recently.
Design
Unlike the CineSkates that includes 3 wheels to the feet of GorillaPod tripod, Pico Flex is similar to that of the regular real Dolly. The simple dolly is built on a 4-wheeled aluminum camera platform. Both the urethane wheels can be locked and can be moved in one position.

If users prefer to use their own friction arm, cam can be mounted on the platform. You can also mount the camera on various positions. An optional 11-inch arm can be supported to the dolly. You can find total three mounting points on platform, so few additional arms holding lights or lens flags can also be added.
