DO-RA Team is Taking Part in Google’s Project Ara Contest

It's the taking part that counts!

Some time ago Google announced a prize of $100K for the winners of the Project Ara contest for developers of a modular smartphone with replaceable electronic modules in a form of decks united mechanically on the smartphone’s endoskeleton already designed for this purpose. Within the project, all participants are invited to develop their own useful electronic modules of the following dimensions: 20х20х4, 20х40х4, and 40х40 4 mm. The module tendency is penetrating the IoT world step-by-step. Presently, there is a number of devices already available with easy-to-change electronic modules you may order and buy in various e-stores.

The DO-RA team as a part of JSC Intersoft Eurasia (a Skolkovo Resident in Nuclear Technology Cluster), has decided to try its fate and take part in Google’s open international project, experience a cooperation with international design teams, and ensure an additional stream of orders for its future products of its DO-RA.Module line.

The project application process is fast and smooth: a to-be-participant has just to fill in a form at and download design requirements for the device in section for developers, and off we go! The terms seem to be severe, but practicable. Google promised to provide all accredited participants with its Module Developers Kit (MDK) for Android mobile platform and detailed instructions.

JSC Intersoft Eurasia filled in the required forms and entered the project in August, 2014.


DO-RA.Module Function

So, DO-RA.Module function for Ara project is to develop a unique line of ultra-compact dosimeters under single brand DO-RA, based on devices and techniques (patented in Russia, USA, China, and Japan) of silicone detectors production with world class performance under its own brand DoRaSi, including reading electronics with a set of user programs DO-RA.Soft in 23 languages and original branded design.

Presently, we have completed development of a 18х18х4.5 mm device of the DO-RA.Module line based on our proprietary solid-state radiation detector patented in Russia. Within Ara project, our device is required to use signals of i2C lower level protocol, and everything else would be processed by the Ara smartphone processor. All modules will have common power supply (3.5 V).

The range of environment, subjects and food radiation measured with DO-RA.Module depends on modification per Energy range γ-, β- α- and is from 0.05 to 10,000 keV at relative sensitivity of ±10 % within 10–100 s.

Based on results of this work, it is possible to plan production and distribution of radiation indicators featuring the DO-RA dosimeter-radiometer function compatible with Google modular smartphones on Android mobile platform and other OSs (iOS, WP), as well as those controlled by MacOS/Microsoft/Linux. A participation in the Google project provides a solid advertising support and an ability to apply DO-RA.Module items in different devices, including smartphones, pads, laptops, and desktops.

DO-RA.Module modular solutions have positive outlooks of being used in motor cars within navigators and video registers, as well as in home appliances, which are coolers, freezers, boards for food and liquids storage for centralized and personal environmental monitoring. We have received first orders for DO-RA.Module modifications from South Korea, Japan, and China.

Development and deployment of DO-RA.Soft applications have been adapted to Google’s global web-map to monitor environmental radiation conditions, including that in areas where nuclear facilities are based, both in the Russian Federation and abroad; such application may also be used by people in their everyday life and will be helpful in case of accidents involving fissile materials.


How it works

To clarify why DO-RA.Module is necessary in life and to convince the Google’s Project Ara contest board we demonstrated a video provided by Russia Today and shoot for their Technology Update program.

The camera operators shoot our developments last winter, but redundant radiation monitoring is still a pressing issue today and will be in future. Particularly it is true for air travellers, flight attendants, and pilots, since during a flight at a standard route height of 10.5 km above ground level they receive a radiation dose which is 20–30 times higher than the normal ground one. By the way, up to 1 billion people travel by plain during a year, so it is a promising market for gadget with such features.

So we inserted the video from Russia Today in our DO-RA.Module 3D animation prepared specially for the exhibitions in Hong Cong and Seoul arranged by Skolkovo and, frankly speaking, we deem it a comprehensible visual material for Google’s Project Ara contest board which you can find at
