There are no mechanical harvesters for the fresh market apple industry commercially available. The absence of automated harvesting technology is a critical problem because of rising production costs and increasing uncertainty about future labor availability. This paper presents the preliminary design of a robotic apple harvester. The approach adopted was to develop a low-cost, ‘undersensed’ system...
The existing simulated mouses are mostly based on the hand tracking technique, which depend on the data gloves, remote controllers or other equipment, leading to high costs and severe user limits. In this paper, we develop a new kind of simulated mouses by employing dynamic hand gesture recognition in which the palm node is detected by a Kinect camera. According to the movements of users in real world,...
How to make mobile manipulator autonomously identify and locate target object in unknown environment, this is a very challenging question. In this paper, a multi-sensor fusion method based on camera and laser range finder (LRF) for mobile manipulations is proposed. Although the camera can acquire rich perceptual information, the image processing is very complex and easily influenced from the change...
CCD image usually has a huge amount of data with high-resolution, therefore it is difficult to capture and browse the image real-timely in real project. In the traditional capture and transportation systems, we usually first capture and store the image into storage medium, then read out the CCD data for browse later, but this method is not good for diagnosis and debugging real-timely. For eliminating...
With the working environments of the spherical robot become increasingly complex and unstructured, we must improve the autonomy of the robot. As a new mobile robot, the reliable navigation system and accurate sensory ability is very important. The paper presents a monocular vision-based path identification algorithm for a spherical robot moving in an unknown environment. The robot explores the environment...
It is vital to calculate the relative position and pose in many important space missions, such as space formation, rendezvous and docking, space capturing and maintenance etc. It is a direction to get the relative position and pose based on computer vision currently all over the world. And this method is also valid for spacecrafts. In this paper, on the basis of the attitude dynamics of spacecrafts...
The development of an in-field plant sensing system for a site-specific application can protect the environment from excessive chemicals and save management cost while maintaining productivity. A multi-spectral imaging sensor has been introduced and widely used for in-field plant sensing. In order for a robust performance of the spectral imaging sensor under changes in ambient illumination, image...
