DroneVolt’s Janus VR Bot is a 360 camera rig on a remote control dolly. I don’t know much about it except that it seems to use a Freedom 360 rig which uses six GoPro cameras for up to 8K resolution.
B&H Photo has the Janus VR Bot listed at $14,350 without any specifications yet. I’m not sure if the VR Bot includes the Freedom 360 rig and/or the GoPros for it.
In the meantime, B&H also has the Janus 360 drone for two Freedom 360 rigs, for about the same price (the price excludes the cost of the Freedom 360 rigs) You can check out a sample video from the Janus 360 in this previous post.
