1 Saint-Petersburg State University of Aerospace Instrumentation Robot Phoenix-1 Design Authors:Goncharov A. Miheev A. Jan 2007

2 Introduction : Phoenix Project “Phoenix-1” was started 02/04/05 and was realized by mixed student and engineer team during autumn semester. Backbone of team is formed from students (4221 and 4022 student groups) and engineers of Student Design Center of SUAI. Mobile robot PHOENIX-1 orients in external environment with web-cam and has to follow a white stripe of the arbitrary shape

3 Control System of Robot : Phoenix Left and Right Motor Control Bridges RS-232 Web- camera Laptop Toshiba Controller ASK-Lab Rotation Speed Sensor -1 Rotation Speed Sensor -2 Actors Sensors High level Low level Laptop gets video images from web-camera and processes them. Controller gets data from speed sensors and sends them to laptop by RS-232 using protocol ASK-Bus 3.1. Backwards controller receives control commands from high-level program. Controller converts this control commands into executive signals to actors: PWM left, PWM right, Direction of rotation left, Direction of rotation right.

7 Radio Control : Phoenix Operator sees robot by his own eyesight and control movement of robot by control console by RF channel. 2.Operator’s control commands are transmitted to robot’s controller, where they are converted to executive signal to actors (motors). 3.Video from camera and sensors signals are written to laptop’s HDD. 4.Later, the saved video and sensors information are used to teach neuron.

8 Radio Control : Phoenix Video from camera is compressed and transmitted to operator’s PC by Wi-Fi. Simultaneously, video and sensors signals are written to laptop’s HDD. 2.Operator sees video image and uses joystick to move the robot. 3.Operator’s control commands are transmitted to robot’s laptop and are converted to executive signal for actors (motors). 4.Later, the saved video and sensors information are used to teach neuron.
