- We are using a Pixhawk as flight controller, IR precision lock for autonomous landing and raspberry pi for autonomous flight. We are using Qi wireless chargers for wireless charging.
If you like this video, you might find my senior thesis interesting. It is on my linkedin.

Cam you provide links for your thesis... The current links are not working
May I suggest a modification,. Instead of Wireless charging pads, make them electrical contact pads. Then apply the charging voltage to the drone via AC voltage, and use a bridge rectifier placed on the drone between the pad contacts and the battery. Then you never have to worry about reverse polarity from landing in the opposite direction. Use the four pads but make those electrical contact pads with four contact points or two contact points on the drone
The downside is that will require extra equipment into the drone to do the charging.
I don't think that landing in a fix direction is hard. The drone has an internal compass.
I would use the pads as DC + and - and RX and TX for communication.
please help me with this one, how can you cut the supply to the motors when it lands and put the supply again when the charging is complete? thank you
the flight controller knows when the drone lands, so you can easily program the drone to stop keeping the motors on when it lands. Theoretically, you can program the drone to turn on the motors again when the battery voltage goes above a certain level after charging (we haven't tried this).
It's called arming and disarming the motors. Most flight controllers have a way to arm and disarm them.
Amazing job guys, I myself have been trying to create the same thing, The landing pad box I thought of as well and the wireless charging pad I have thought of but because of their low output I never thought of using them in parallel as you did, that is a great idea. In my version I am manually landing the drone at its own point and this way it's always ready to launch. So I give you guys a ton of credit. Great job
I had this idea pop up in my head and wondered if someome else had already done it. Now that I know someone has, I need to one-up this concept or expand on it!
All the best!
can please send me the details how wireless charging made by you like how you connected coils to battery and all those things because we are making a drone contains wireless charging . we failed nearly 22 times
5 stars I've been working on a vary similar for a year now only difference is I have 2 power sources as we dont have sun all day and I added lidar with camera to really lock in landing and help stability I was thinking of having an offline but yet autonomous drone to prevent hacking theres a way it's a slow process and I'm alone keep up the good work you guys nailed it
Great concept. Futuristic technology for the aviation industry.
Thats pretty cool, whats that circuit you have between the solar array and the charger? And for the DC converter how much energy did you lose? is that uno connected to the charger ? too many question I know haha but its just pretty interesting!
there's a diagram of the circuit between the solar array and the charger on my thesis if you are interested. I don't think we checked how much energy we lost for the DC converters. I think they are advertised to be at least 90% efficient. The uno is not connected to the chargers. The function of it is to prevent the battery bank from over discharging and damaging itself
Hi guys, this is impressive. Nice idea, suits perfectly into a project in view (few modifications to be added though), are you open for a partnership?
sure, if you have questions message me on linkedin and I will try my best in pointing you the right way.
Great job guys. There are no links in the description though :/
Thanks for pointing it out! We added a few relevant links.
hello guys, excellent work they are doing, but my question is: how do you finish the charging cycle once the battery has been fully charged?
That is a good question. Due to lack of time, we haven't implemented something in our system that tells us that the battery has been completely charged. But I can think the following could be one way this can be implemented:
The drone flight controller, Pixhawk, knows what the battery voltage is. So it could send a signal through a Bluetooth system to the charging station to turn off power to the wireless charger when the battery voltage is at a certain level.
You could use a battery management system in conjunction with the battery, it'll automatically balance the battery cells, and prevent an overcharge or discharge. The base could then just use an ammeter to determine when the battery is done, as once the BMS cuts off charging, the current will also drop off.
This is awesome! what battery and BMS are you using on the drone?
Awesome.. Any training available.. I want to build for myself
How that drone is flying while charging
I want to do this in my dissertation, could you help me ? I have sent you a request on linkedin as well.
looks like a good recon / security perimeter.
Great jobs guys!!!
funnel idea is fantastic
I would like to buy one can you call me
that was good
Good
So basically you built an automatic battery charger but you still have to land on the chargers? Its really not that hard to plug in a battery yourself. Put the solar panel on the drone connected to the drone battery and never land.
Doing something similar for a project; how long does it take for the drone to charge?
It takes about 5-6 hours. You can read my thesis (link in description) if you are looking into charging it faster.
