This work presents the design of a wheeled mobile robot (WMR) using an Ackerman configuration. Its design uses the extruded aluminum profile widely used in industry, facilitating the assembly of new robotics projects. The design is carried out using CAD software and shows some of the various benefits of these tools. The environmental impact values for a bar of extruded aluminum profile throughout...
The Robot@Factory competition was recently included in Robotica, the main Portuguese Robotics Competition. This robot competition takes place in an emulated factory plant, where automatic guided vehicles (AGVs) must cooperate to perform tasks. To accomplish their goals, the AGVs must deal with localization, navigation, scheduling, and cooperation problems that must be solved autonomously. This robot...
A vision-based autonomous vehicle tracking robot platform has been designed and developed where a video camera mounted in front and on top of the robot is used to capture the environment to provide real-time monitoring and tracking. The image processing is done in MATLAB where the output decision is used to guide the robot's navigation. A differential drive mechanism implemented using two DC motors...
Autonomous vehicle navigation requires the integration of many technologies such as path tracking. In path tracking design, we must take into account the dynamic of actuators in order to reduce overshoots appearing for small displacements. It permits the generation of an optimal movement reference-input giving a minimum path completion time, taking into consideration the maximum velocity, acceleration...
The inverted pendulum problem is well-known as a good application for control engineering. An autonomous robot can use the principle of the inverted pendulum for its design. A two-wheeled robot has both static and dynamic design considerations when using the inverted pendulum principle. This paper investigates the effect of varying mass characteristics on the step response of a self-balancing materials...
Aerial robotics provides many practical applications in fields such as search and rescue and surveying. In order to advance the research in aerial robotics, an inexpensive test platform is required. Our four-rotor platform provides researchers with a inexpensive, fully scalable test platform for future studies. Its completely on-board processing removes the need for a virtual tether in the form of...
