John Smith asked What kind of remote control system is used in this, I wonder?
I watched this video just now and I am quite surprised. ----------------------------------- http://www.youtube.com/watch?v=on4DRTUvst0 ----------------------------------- To me, this new delivery system looks so cool and I want to make that kind of robot someday. It's a quite surprising fact that you can control the robot in such a long distance, so I begin to wonder what kind of remote control system was used for that robot. I want to control my one at least 5~10km from where I am so I guess I need to study a high-end technology...? Please borrow your wisdom for a bit everyone! Correct me if I have a wrong idea! And If possible, I want to know about the power source too... thank you in advance!
And got the following answer:
This is shot entirely for show. The system used is a standard spread-spectrum (spektrum) radio with a best case scenario LOS (line-of-sight) range of 3-4 mi (5 ~ 6.5 km) which is slightly better than standard RC radios. the exact radio used is listed in the sources below. If you need long range radio control without video checkout http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/point-multipoint-rfmodules/xstream-module these are what I use for my business and projects. They require some electrical engineering knowledge as well as a good programming know-how. But this or something similar is likely your best bet for the range you are looking for. (20mi or 32km bestcase LOS) The video inflight is all recorded in-situ (in place not transmitted) on a GoPro. transmitting decent video is actually one of the hardest things to do at distance. In my personal experience I've found it more difficult to transmit quality HD video at distance without major interruption than to get a drone to fly autonomously. If you are not traveling outside cell range one of the more clever things I've seen done is to actually mount a cell phone inside a plane and use a custom app and streaming plugin to control your craft over the cellular network. Haven't tried it myself yet but I will soon it looks promising. the problems with streaming over a call network is delayed video and relayed commands (by several seconds) which for a non fully autonomous craft is surely fatal. and potentially spotty coverage also fatal to non fully autonomous craft. This octocopter has eight high speed brushless dc motors. With all eight of those running, and a payload like that pizza, even with good lithium polymer packs you would be doing really good to get in a 10 minute flight. DIY drones are a lot of fun but so much more difficult and labor intensive than one would have thought.
