This project is to develop a robot to explore the version 3 performance over previous versions of survey robot because robots explore version before there is a problem. The story of signal control signal display animation. The command control signals relay logic relay collision occurs, the command prompt does not follow the error control and can not save an image on the display screen. Design and structural changes, new exploration robot, go up the stairs. The control range is farther up the ramp is tilted more than 25 degrees, more camera views. Fixed the error of command robots, before using the Arduino board version of the survey, which is a microcontroller to control the robot and makes exploring the images saved transmitter display screen.
