Robot orientation with histograms on MSL

One of the most important tasks on robot soccer is localization. The team robots should self-localize on the 18 x 12 meters soccer field. Since a few years ago the soccer field has increased and the corner posts were removed and that increased the localization task complexity. One important aspect to take care for a proper localization is to find out the robot orientation. This paper proposes a new technique to...

Vision-based hand segmentation techniques for human-robot interaction for real-...

One of the most important tasks in hand recognition applications for human-robot interaction is hand segmen-tation. This work presents a method that uses a Microsoft Kinect camera, for hand localization and segmenta-tion. One important aspect for robot control besides hand localization is hand orientation, which is used in this work to control robot heading direction (left or right) and linear velocity. The sys...

Catadioptric system optimisation for omnidirectional Robocup MSL robots

Omnidirectional Robocup MSL robots often use catadioptric vision systems in order to enable 360º of field view. It comprises an upright camera facing a convex mirror, commonly spherical, parabolic or hyperbolic, that reflects the entire space around the robot. This technique is being used for more than a decade and in a similar way by most teams. Teams upgrade their cameras in order to obtain more and better in...

A golf ball picking robot design and development

The golf ball picking task is a daily that requires human intensive labor. This document presents the hardware developing process of an autonomous golf ball picking robot which aims to efficiently perform this task. It has a maintenance capacity of a 25,000 m2 practice field. Compared to a similar device in the market this robot has twice the maximum speed and three times more container capacity.

Bot’n roll robotic kit as a learning tool for youngsters

Activities involving robotics, projecting assembling and programming robots are in essence hands-on and inquiry-based activities leading to an effective learning of different aspects of science and technology among others. Different approaches have being used to introduce robotics in the education of young children. In this communication we will present an approach that in an inquiry based science education, IB...
