I've put so many hours into this project. The grey foam and everything in it is new but it's also the most interesting part of it all. There is an FPV pan/tilt/roll gimbal on the front of it which stabilizes the main camera on top. In the back there is a second camera that I can use as a reverse camera. On the left is the control board which staibilizes the front camera gimbal and under it is a camera switch and receiver. On the right side is the video transmitter mounted under a fan to keep it at a safe temperature. It is powered by 3 different batteries. One 2s lipo powers the fan, another drives the wheels and gimbal rig, and a separate 3s lipo powers the transmitter and cameras. It may seem like a complex system, but I'm finding it to be a simple one. My biggest problems with the system are that the wheels are pretty weakly held to their servos and the wire management in this thing is a nightmare. Now I have a set of 4 bright LEDs mounted to the front of it to help me see in dark areas.
