Micro Quadcopter - does that count as a robot? :-p

Not sure if a quadrotor count as a robot, but that's somethting i have been working on and I would like to share with you guys.

There is quite a lot of stuff to learn and take in, in order to build a quadcopter from scratch: buying parts of your favourite choice, select a multicopter software, build the frame yourself, assemble the parts, PID gain tuning, countless test flights and crashes, and finally improving your fly skills :-)

A flying machine doesn't has to be huge. It can be smaller enough to fly in your room. It's now winter and it rains a lot in England, so I definitely wouldn't be able to spend too much time outdoor. Flying a quadcopter in my room would be a perfect spare time activity. 

This micro quadcopter I built is 19cm x 19cm, and the weight is 230g with battery, flight time is about 10 mins. 

Because I have never built a quadcopter this small before, I bought everything from Hobbyking including the frame to make sure everything is working, before I do any crazy customization. Although it might cost more, but by saving money on something that doesn't work, doesn't sound like a good deal to me either. Later on I DIY a much lighter frame using fibre glass rods and styrene sheets, so I have more room to carry a FPV system and GPS module in the future.

I built this quad at about £80. Parts I used:

• Flight controller: Arduino Nano + GY80 (and sometimes KK2.0)
• Prop: 5030
• Motor: 18-11 2000kv Brushless Outrunner (10g)
• ESC: TURNIGY Plush 6A
• Battery: 950mah 2S

I will keep updating my project post on my blog.
