I recently watched a sUAV real estate video for a 6 million dollar house. The exterior video was great but as they carried the uav through the house you could see every step they took. I thought I could make a rolling dolly to carry a xstar to smooth out the video. It had to be easy to turn so I used 5" swivel casters . I mounted the tablet at eye level so I could watch the video stream. I made a handle to pivot it and push with. The first video looked better than I hoped for. I see some improvements in stability can be made to the base and I am going to change out the bungee cords to some Velcro and rods to reduce swinging. Right now I have $33 invested. When I finish the upgrades I will post them and some video. Let me know what you think of the attached videos
