  • Wifi Video Streaming Mars Runt Rover (inspection Bot)

    Thank you! Regarding video quality, That was a steep learning curve. Higher quality cameras and units got horrible lag. It turns out that the lower resolution webcam units are better because they send data thru WIFI so much quicker (smaller pictures upload nearly instantly) Where as the newer units wont adjust to any resolution below 720p HD. The wifi lag is much higher and thus makes it harder to drive the unit remotely. When selecting the camera, You want to ideally use 720p or less to stream your video. Actually the smaller the video quality, the faster it will stream and the less video lag you will experience. You sorta trade picture quality for speed.I know the 1080p webcam I have is literally undrivable. It has a 2 to 3 second video lag meaning I can move my car, an...

You sorta trade picture quality for speed.I know the 1080p webcam I have is literally undrivable. It has a 2 to 3 second video lag meaning I can move my car, and it wont show up in video that it moved for 3 seconds. I usually have already ran into a wall in that time and cant tell till the video catches up. High res cameras are useless like that.I also found that driving the unit from a Ethernet connected computer gives a great reduction in video lag as well.I can only assume that its because the video is traveling only one direction from the car to the router, then from the router it is routed into ethernet. When I drive the car from my laptop, I experience much more video lag I believe to be a result of the video coming from the car in WIFI, to the router, where the router then has to route the video across WIFI a second time to my Laptop. So there is a load sharing process going on with laptops vs ethernet connected devices.
