ABSTRACT:
Getting a driver’s license marks a milestone for most teenagers on their journey into adulthood. As a matter of speaking, robotics technology has also matured over the past three decades to the point where it too is ready to claim a driver’s license. Significant recent advances in information processing, machine vision, control theory, and signal processing— in both hardware and software—increase the capability to represent, analyze, perceive, and respond to dynamic road conditions. In this issue, we feature the latest developments in ground-based unmanned autonomous vehicles . The architectures for those mechanisms are also given. How the vehicles can communicate with the other vehicles?, how the vehicles can detect the road conditions(eg: speed brakers), obstacles(eg: trees) and the environmental conditions (like smog) ?are discussed.
Unmanned ground vehicle technology has evolved in fits and starts. Researchers are considering unmanned vehicle technology for many applications. Ever-increasing personnel costs are prompting consideration of the technology for agricultural, demining , rescue ,and other dangerous applications. There would be a decrease in the number of individuals put at risk and an increase in operational efficiency if a vehicle could move autonomously , plant seeds , enter minefields ,or perform dangerous missions. All these are the advantages of the autonomous vehicles. This clears the need of autonomous vehicles or unmanned vehicles.
Now, we move to the implementation part of these vehicles-Early research focused on providing advanced assistance for drivers, the success of which has led to the bolder vision of complete autonomy.Initially a custom architecture in which SIMD paradigm had used. Later SIMD with extension for the image and sound processing has used. At those times they had faced the problems of integrating the various teams or methods.To prevent the integration chaos typical of large, disjoint teams standardized Joint Architecture for Unmanned Systems component systems and messaging framework has developed. JAUS aims at creating plug-and-play unmanned systems, where sensors from one vendor can seamlessly be swapped with those from another..,This new method will include those detections also using the image processing techniques. This is the overall thing about this topic.
