As the working environment for intelligent mobile robot is complex and changeful, there is a higher requirement for the obstacle avoidance ability of the robot. With the Enhanced Vector Field Histogram method (VFH+), it does not consider the change of obstacle’s position and direction and robot’s real-time speed. For this reason, an improved method, called Mobile and Static Vector field method (MSV),...
The whole model of household mobile robot is designed according to the actual requirements. It includes three subsystems: remote human-computer interactive subsystem, PC server subsystem and semi-autonomous decision-making mobile robot subsystem. The motion model of semi-autonomous decision-making mobile robot is constructed. Low performance DC motor and low resolution code disk can cause inaccurate...
The driving speed of mobile robot is always inaccurate driven by low performance DC motor and low resolution encoder in PWM way. For this reason, the event-driven dual-driving-wheel synchronization control model is established based on Petri net. The forward and inverse formulas of the azimuth for dual-wheel-driving mobile robot in discrete form are deduced. The specific realization algorithm is given...
A wireless communication: Bluetooth technology-based mobile robot is introduced. It can steer clear of obstacles automatically, download route programs online and transmit image data real-time to the central computer through Bluetooth communication. It has the function of remote control. The control of the motors adopts double closed-loop and the control commands are processed by the embedded operating...
