At the Massachusetts Institute of technology have developed roboscooter Bashny.Net

The development of automatic systems of control car doing now many companies, both foreign and domestic. Such systems can be fully automatic — such developments Google is doing so and in part (the digital assistants of different types). By the way, the digital assistant is Autopilot Tesla Motors. It's not autopilot in the full sense of the term. The developers of mit (Massachusetts Institute of Technology, MIT) have decided to create another, and a robotic scooter. The project was developed in cooperation with organizations such as the national University of Singapore and CSAIL (Artificial Intelligence Laboratory).



Earlier, the same team of researchers has been studying the possibility of creating automatic Golf carts. For them developed a special software platform that with some changes and additions and used in the new project. Scooters with automatic control system, according to developers, can be used, for example, those people who are unable for any reason to walk independently. Such systems can be useful to private users and companies.

Now developers check the performance of the algorithms of the software platform inside the building, although it all works, and on the streets. Work scooter has already been tested in some areas of the Institute MIT, where a rather intricate system of corridors, which causes complexity not only of the automatic control systems of vehicles, but also in humans. "One of the places we've tested is the "infinite corridor" at MIT, navigating which can be a real challenge, since it is a long passage with a number of obstacles. You can easily get lost up here. But our algorithms showed good performance in the new environment," said Scott camp Pendleton, one of the participants of the project. The transfer length is not large — a total of 251 meter.

The software platform consists of several layers. The first layer is a low — level algorithms, which allow the scooter to navigate in a dynamic environment, avoiding, for example, along the way people. The second layer is the algorithms that control the direction of movement. The third layer algorithms that allow the system to identify your location. In addition, the developers have developed algorithms that, analyzing the situation around, Carteret area.

Developers MIT believe that it is necessary to use a unified platform to control the movement of scooters, Golf cars and city cars: "If you have a single system that runs the same algorithms, the complexity of such a system is much lower than in the case that all systems are different". In particular, unification allows to transmit data collected by one vehicle to other vehicles and scooters. All these vehicles will be able to work with a single database, in contrast to situations where different vehicles operate with different software platforms. Data transfer from one Golf cart to another were tested by the developers in Singapore.

Software platform, which is equipped with scooters and cars, is a self-learning system. Constant interaction with the environment improves the accuracy of algorithms.
 



Another advantage of working with a unified platform — monitor-free vehicles without the need for an integrated single monitoring program in the software platform of different type. Vacated cars or scooters themselves declare their availability, and this information is displayed on the user device.

Developers at MIT have managed to create a scooter with automatic control in just two months. Of course, as mentioned above, the software part for vehicles has already been created and work, it remained only to adapt to a new type of vehicles.

Autonomous scooters were experienced by the volunteers. The desire to test the system was expressed by about a hundred people. Directly before testing and after these people were asked to assess the safety devices on a scale of 1 to 5, where 5 is the feeling of maximum security. The average rating has increased from 3.6 points (to testing) to 4.6 (right after them). According to the authors, this suggests that, in General, the development was successful.

The results of their work, the participants of the project presented at the international conference of the IEEE in intelligent transportation systems ( IEEE International Conference on Intelligent Transportation Systems), which was held last week in Rio de Janeiro, Brazil. published
