This paper deals with control system of skid steered robotic vehicle. Skid steering offers very simple way to achieve good traction on rough terrain. On the other hand it is difficult to precisely control the speed and the position of the vehicle. The presented solution uses modern approaches to control drives of the robotic vehicle such as visual odometry with stereo camera in combination with precise...
An omnidirectional Mecanum base allows for more flexible mobile manipulation. However, slipping of the Mecanum wheels results in poor dead-reckoning estimates from wheel encoders, limiting the accuracy and overall utility of this type of base. We present a system with a downward-facing camera and light ring to provide robust visual odometry estimates. We mounted the system under the robot which allows...
The design and novel features of a reconfigurable modular robot, called iMobot, with four controllable degrees of freedom is presented in this paper. iMobot, which is designed for search and rescue operations as well as other applications such as research and teaching, has versatile locomotion, including a unique feature of driving as though with wheels and lifting itself into a camera platform. Future...
Nowadays, due to the involved complex issues, teaching robotics is demanding new methodologies. One of the complex issues regarding robotics is the use of computer vision for a proper robot guiding control. At the University of Brasilia an educational robotic workstation around a Rhino XR4 robot was built. Students can perform experiences on kinematics, trajectory generation and motion control. A...
