4 arms fold out and click on into place and on the top of every you’ll discover plastic rotors. There’s undoubtedly an artwork to opening and shutting these arms, however with my time with the gadget it by no means as soon as felt like I may harm the blades.
The unit itself is constructed from a pearl-coloured white plastic and weighs in at just below 200g with the battery hooked up. The ability button sits on the highest, whereas the underside is house to the battery compartment.
The battery may be unclipped and positioned within the bundled charger for prime up, and filling up takes round an hour. A button on the battery may be pressed to point how a lot juice is left; it’s denoted by a financial institution of 4 inexperienced LEDs.
Additionally on the underside of the unit you’ll discover an optical sensor and ultrasonic wave sensor, each of which assist the drone stabilize itself when used indoors.

Zerotech Dobby – Options
Given the Dobby’s remit as a “selfie” drone, it must be no shock that a lot of its performance revolves round pictures. The 13-megapixel f/2.2 CMOS lens can seize photographs as much as 4,208 x 3,120 pixels in decision, producing pictures of a usually first rate normal.
In contrast to different drones in the marketplace, the Dobby doesn’t include its personal distant management; you’ll want Zerotech’s Do.Enjoyable smartphone utility, which is out there for each Android and iOS.
The app makes use of Wi-Fi to hyperlink itself to the drone, with each 2.4GHz and 5GHz requirements being supported. Single, burst and even time-delayed photographs are doable, and as soon as a photograph is taken it’s saved within the Dobby’s 16GB of inner reminiscence earlier than being downloaded to your handset by way of the Wi-Fi connection.
Video seize is probably a extra spectacular utility for the Dobby drone. 1080p video operating at 30fps is feasible, and Digital Picture Stabilization helps compensate for the slightly jerky motion – one thing that’s exacerbated while you’re piloting the Dobby in a windy location.
Naturally, guide management is somewhat jumpy, however there are a number of computerized flight applications that you need to use to get a smoother shot. One locations the drone in an orbit round a particular location; one other can observe you as you progress round.
Face monitoring can also be supported, however is finest reserved for close-quarters filming. You too can make use of some dramatic monitoring photographs that trigger the Dobby to pan elegantly backwards, recording because it drifts away earlier than returning to its earlier location.

Zerotech Dobby – Performance
Given that it’s a consumer-level drone, the Dobby’s performance is impressive. It’s capable of flying to a height of around 300 meters above sea level and maintaining its position with a remarkable degree of accuracy, even when it’s being buffeted by relatively strong wind.
The on-board Qualcomm Snapdragon processor – combined with Zerotech’s library of algorithms honed over a decade of development – ensure that the Dobby is a stable flyer. On the downside, it’s rather noisy, so don’t expect to use it in public places without being noticed.
When it’s outside, the Dobby uses GPS to track its position, but indoors this isn’t possible so it relies on optical and sonic sensors, which are located on the bottom of the unit. These will keep the drone stable up to a height of around 3 meters; it’s quite impressive how precise the unit is when used in this environment.
However, the lack of side-mounted proximity sensors mean that the Dobby can’t avoid obstacles such as furniture, light fittings or people, so it should be used with caution indoors. Optional rotor guards might be a wise investment, since these will prevent the drone’s blades from becoming damaged – or it damaging something else.
Once you get Dobby up in the air and become accustomed to its controls, it’s possible to take some amazing shots – shots that simply wouldn’t be possible without a drone.
You can see a selection of photos taken on the Dobby Drone below.
While the camera quality might not match that of your smartphone, the fact that you’re able to snap locations from such an elevated point more than makes up for it.
Video recording, too, is excellent – although you’ll almost certainly want to turn on the EIS feature if you’re looking to control the drone manually. This reduces judder on the final video, but be aware that it can result in black areas around the edges of the final video as the EIS “locks” the image to stabilize it.
By far the biggest limitation with Dobby is its stamina. Zerotech quotes around nine minutes of flight time per charge, and as you’d expect, this is being quite generous. If it’s a windy day and the Dobby is having to compensate to maintain its position, you’ll notice that the battery drains much quicker. In addition, activities such as recording HD video and taking photos will naturally consume more power.
The bundled charging dock does top up the 970mAh battery swiftly, but it goes without saying that if you’re serious about making the most of this drone, a spare battery is a must. It might also be a good idea to invest in a large-capacity USB power bank so you can charge Dobby’s expended batteries when you’re out of the house.
