Technical characteristics of the wheeled robot SRX1




Autonomous wheeled robot SRX1 able to make auto travel on the programmed route without human intervention. The robot is made to move along the paths, which ensures reliable tire grip with the surface. It may be asphalt, concrete, gravel or dry soil. The robot is not intended for movement on highways of General use. Best speed and reliability of movement is achieved in unpopulated areas. Its operation is difficult, and sometimes impossible during the regular movement of people and vehicles.

Autonomous ground wheeled robots have great prospects of use in people’s daily life. They become reliable assistants in the performance of professional and household tasks. In contrast to the anthropomorphic humanoid robots, wheeled robot has an affordable price. This price makes it worthwhile, cost-effective use of them now. The secret to the effectiveness of wheeled robots in the subspecialty solve the robot tasks and the use of generic robotic platforms.


Automatic control of the movement of the robot day and night:

Automatic control of the movement of the robot along the route is based on the recognition of images with onboard cameras. In the daytime wheeled robot focuses on the visible landmarks in the field of view of two cameras aimed forward and backward. This method gives good results in areas with numerous buildings and other man-made structures. However, it is of little use in open spaces where there are no objects with precise geometry. In this case, the optimal route planning of robot motion on the walkways. Contrast color cover tracks from other surfaces allows you to obtain information sufficient to correct the path. In combination with satellite navigation system this method allows you to make high-precision drives.

When the automatic driving at night, and the route was lit by street lights. For reliable navigation enough illumination adopted for pedestrian walkways in the city – 10 lx. If any section of the route required illumination can not be obtained, will require the installation of night markers. You can place them on poles or walls of buildings.

The obstacles in the path of movement of the robot, are detected built-in stereo cameras. The algorithm of processing of stereo images allows to calculate the distance to the obstacle and to choose the optimal path of the detour. In the case of traffic obstruction, causing considerable deviation from the assigned route of movement, wheeled the robot will automatically stop. The stereo camera of the robot, specify the path of travel while moving along a curb or a solid fence.

For reliable operation of the system of detection of obstacles at night wheeled robot equipped with a headlamp. Headlight turns on automatically at dusk or when the local low light footage of the upcoming movement.


Remote monitoring and motion control of the robot:

The selection control routes of the robot is implemented with a tablet computer running the Android OS. For this purpose developed software application, “Multi-Robot”. The connection between the mobile computer and the robot are in motion, and is carried out through Wi-Fi. The software user interface allows to control several mobile robots on a single object. Interruptions in the wireless communication channel do not affect the movement of the mobile robot. Once in the insecure area of the network WiFi robot sooner or later will leave her alone and restore the transmission data stream of the image.


Programming the path of motion of the wheeled robot:

Robot teaching route is carried out with the installation of robots on the object of exploitation. On the basis of Google Maps or Yandex Maps the electronic map of the paths of the driveways. Along the route markers are placed in increments of 50 meters. Using the remote control or a tablet computer, the installer holds the robot in all possible paths or driveways in the manual control mode. Wheeled robot learns the trajectory of motion, transfers it to an electronic map and links to her visual landmarks along the way. The operator has the possibility to adjust the route to manoeuvres, destination and priority targets. Then the robot runs on a route in automatic mode, with the aim of accumulating information about the visible landmarks in various lighting conditions.

The best results are achieved when the training passages in the light throughout the day with variable cloudiness. Over the next several days, the robot travels the route in the test operation mode. In this case, the markers remain in place, but are in the off position. If time and reliability of route sufficient tokens are removed and the robot is ready for operation. In terms of seasonal changes in the surrounding landscape may require re-training in a similar way.
