Frequently Asked Questions
I can confirm ZANO will come complete with a 5 megapixel HD video camera upon launch!
Due to size and weight restrictions, ZANO's camera is fixed at this stage. However, ZANO supports "windowing", which through software, allows a user to pan and tilt the captured image to get the desired angle and frame.
We are currently in discussions with our camera supplier to source the same camera with a fish eye lens, which will allow for a wider field of view and subsequently allow the "windowing" to greater degrees of freedom!
Any zoom on a camera this size will be digital.
Due to WiFi bandwidth restrictions the video resolution will be restricted to 720p, the camera itself is actually 1080p 60 fps. In future software updates we hope to get closer to 1080p, however, for right now we will be sticking to 720p!
ZANO is small. Physics has a way of making things difficult. Because ZANO weighs less than 60grams, you don't have a great deal of inertia to deal with turbulence.
So what did we do about this?
ZANO firmware has 200% throttle control for each motor and ZANO hardware allows motors to be driven forward or backwards and can change from nearly 100,000rpm one direction to nearly 100,000rpm the other direction in less than 200ms or less than a fifth of a second.
This allows ZANO unlike any other UAV (that we know of), to reverse a motor or motors if stability requires it.
We will post a video shortly showing the speed of ZANO's ability to completely reverse the motors.
What does all this do for you? It makes ZANO much more capable of handling wind and gusts than any other UAV of this size and possibly much better than much larger UAV's.
Can we quantify an actual wind figure? Not yet simply because everything we have done is with our pre-production units. As the weight of the prototype and the production units are different and the production unit has more powerful motors, there will be significant improvements in the production units ability to fight the weather. We cannot give an actual wind gust figure at this stage. To help with stabilisation is another reason to make use of our HPC (Supercomputer) to post process and stabilise video content.
Due to ZANO’s ability to reverse it's motors from full speed one direction to full speed the other direction is less than 200ms (fifth of a second). It also has a good power to weight ratio and some pretty neat stabilisation algorithms so it well outperforms anything else we have seen of it's size and actually quite a bit larger. An actual gust figure will be published when we test the first production versions.Last updated:
Whilst we do not advise flying ZANO in any rain. If you get caught unexpectedly in a patch of light rain, this shouldn't cause any major issue. Especially if ZANO is flying. During flight, the flow of air over the shell of ZANO and through the propellors creates almost an air shield so light rain would be pulled away.Last updated:
One fully-charged battery will give ZANO 10 - 15 minutes of intelligent flight time, obviously this is weather dependent. 80% of power is pulled by ZANO's motors, constant filming or taking photos throughout the flight will have very little impact on battery life!Last updated:
All pledge rewards above and including £139 will come complete with a spare battery!! That means you will receive two (2) batteries when your ZANO is shipped.Last updated:
ZANO comes as standard with an entire set of spare propellors. In the event of motor failure, absolutely they are replaceable.
All spares, including additional spare batteries will be available at www.flyzano.com after the Kickstarter campaign finishes.Last updated:
ZANO is small, it weighs less than 60 grams and as such, the inertia is small. As such, ZANO tends to just bounce rather than crash. Many months back, we were doing some test flying outside our office and to test how tough ZANO was, at 15m altitude, we simply turned off the motors.
ZANO tumbled and hit the car park. Now we wouldn't suggest anyone try this, in fact the software fail safes won't allow this to happen.
ZANO is small and it tumbled, and the impact with the car park outside our office only damaged one propellor. ZANO apart from a few scratches was unscathed.Last updated:
The ZANO app will always be free, bug fixes will also be free for ZANO, after 12 months, because ZANO supports customisation, if we release a function that you want, it will be available as 'In App' purchase. We may release functions you don't want. You only buy the ones you want. These function updates will always be a small cost.
From a product point of view, that is how we continue to be profitable. We sell ZANO which has a huge amount of technology in it, we provide the HPC facility free of charge and our core business beyond building and selling ZANO is adding new functions.Last updated:
The SDK will come in two parts, one will be a library that exposes all the core functionality. This will be available on iOS, Android, Windows etc. The second part will be a prebuilt set of functions added to the raw exposed interface. This would be ideal for connecting ZANO to a web server. The ZANO SDK libraries will take the hard work out of communicating with ZANO, as mentioned previously, these will be in every major programming language from C sharp, Visual Basic, Java, PHP, Objective C, Swift etc. These libraries will expose all the functions and capabilities of ZANO from setting waypoints to retrieving video frames to playing back audio through ZANO's on board speaker.
In the SDK documentation, it will explain how you can make ZANO connect to your own WIFI router and then how you can task many ZANO's all over your own WIFI network or over the Internet. ZANO is not just a one device to one controller, you could with our SDK build augmented reality games, do robotics research, or many other really cool things.
ZANO listens on TCP port 10000 and will attempt to establish communication using its native binary language whenever a connection attempt is made to this port.
The on screen controls are the way our ZANO app works but with the SDK, you can build an interface for a VR headset (We don't want to mention names but there are a few really cool pieces of tech out there that could be easily interfaced for augmented reality projects etc) or an attached phone in a headset like you mentioned. All very possible.
If you’re on a Raspberry Pi, yes, the SDK will support this. If your coding on a windows variant, yes, the SDK will support this, same with iOS and Android. Simple functions such as 'launch' and to your chosen altitude exist. Eg Launch to 1m.
Upon receiving the command, ZANO will launch and hold position until you send another command. All the smarts of ZANO are built into the firmware so the SDK just has to expose all the functions that are available. As we do capability updates, the SDK will grow to expose those new functions too.
As part of the SDK and developer support, there will be ways for developers and users to sign up and make use of the HPC directly through their own code so long as it is related to ZANO content. The HPC sits between a multitude of security measures and every user is sandboxed. This means no way of leakage of one users data to another account, it is all part of the architecture we have designed.
The SDK will be available even if we don't reach the stretch goal. It will simply take us longer to release it.
A ZANO app store will also be launched in which developers can upload their “Apps” for public download.Last updated:
At this stage our intention is to launch ZANO for iOS and Android operating systems. With a view of developing for Windows as demand dictates.Last updated:
The camera we are currently using is an OV5640 5MP camera. This camera is not finalised as part of the production build, the OV5670 is a higher spec camera but it's inclusion will depend on cost at production volumes. The OV5640 5MP camera, itself is easily capable of 720P 60fps and 1080p 30fps. We are looking into other camera modules, as previously mentioned, with higher specifications but that has not been decided yet. We can confirm the camera will shoot initially 720p 30fps and we will then work on 1080p 30fps and 720p 60fps through functionality updates as mentioned previously.
We are working on the optimal angle for the camera and suspect 15 degrees down from straight ahead is about ideal. As ZANO flies forward, for example following you down hill skiing, ZANO would tilt further forward anyway.
The format of the photos taken will be JPEG (JPG) and the videos currently are MPG.Last updated:
