Machine vision implementation for control of parallel mechanism
Zábrša, Tomáš ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
The topic of this bachelor thesis covers issues of parallel robotics. It is focused on challenges of one particular type of parallel robot – delta robot. In this thesis it is described history of parallel robotics, kinematical calculations and machine vision. In the last part of this thesis is description of practical programming of delta robot and palletisation task using machine vision. Parallel robots have, compared to serial robots, certain advantages, but also disadvantages. Parallel robots are more stable, lower mass and they have higher accelerations and can do more work cycles. Using machine vision they can be used for sorting tasks, for example to put product into crates or sorting of machine parts.
Stewart platform – model
Těšický, Lukáš ; Vetiška, Jan (referee) ; Březina, Lukáš (advisor)
The bachelor thesis deals with the creation of a multi-body mechatronic model of a Stewart platform in MSC Adams. There are also analyzed possibilities of utilization of the Stewart platform and other parallel manipulators in the industry.
AC electric linear drive for paralell kinematics structures of robots
Nejedlý, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Design of linear actuator for parallel kinematic structure is described in this master´s thesis. The parallel kinematic structure is described in the first part. Open kinematics structure and close kinematics structure are compared. Their benefits and disadvantages are also mentioned. Construction of some parallel robots is illustrated. Linear actuators of different company are described. Mechanical parameters and construction of linear actuator are compared. Design of linear actuator is described in practical part of master´s thesis. A few variation of linear actuator are introduced. Individual variants are evaluated by Multicriteria Decisional Analysis and a final conception is selected. Final conception of linear actuator is elaborated. Reasons for selection of every part of linear actuator are given and basic mechanical calculation design part is made. FEA analysis of the structural part of linear actuator is made. Design of linear actuator is evaluated in the final part.
The mechanical model of five-bar linkage robot.
Večeřa, Václav ; Chromý, Adam (referee) ; Burian, František (advisor)
This work presents the problem of designing a planar pantograph for the required dimensions of the working space and the subsequent follow-up methods to design the length of the arms, which will ensure this range. According to these requirements, a mechanical model is created. For which is calculated and measured accuracy and precision of reaching the required position dependent on the setting error of the RX-64 servomotors and error in the length of arms due to method of manufacturing.
