Control system architectures for distributed manipulators and modular robots

Thatcher, Terence W. January 1987 (has links)
This thesis outlines the evolution of computer hardware and software architectures which are suitable for the programming and control of modular robots and distributed manipulators. Fundamental aspects of automating manufacturing functions are considered and the use of flexible machines, constructed from components of a family of mechanical modules and associated control system elements, are proposed. Many of the features of these flexible machines can be identified with those of conventional industrial robots. However a broader class of manufacturing machine is represented in as much as the industrial user defines the kinematics and dynamics of the manipulator. Such flexible machines can be referred to as "modular robots" or, where the mechanical modules are arranged in concurrently operating but mechanically decoupled groups, as "distributed manipulators". The main body of the work reported centred on the design of a family of computer control system elements which can serve a range of distributed manipulator and modular robot forms. These control system elements, whose cost is commensurate with the size and complexity of the manipulator's mechanical configuration, necessarily have many of the features found in robot controllers but also require properties of reconfigurability, programmability, and control system performance for the considerable array of manipulator configurations which can be constructed.

Celokovový letoun kategorie UL a LSA s aplikací moderních avionických, řídících a kontrolních systémů / The all-metal aeroplane UL and LSA category with instalation of modern avionics, control and test systems

Kadlčík, Jiří January 2011 (has links)
This thesis is focused on a project of all metal aircraft by UL-2 and LSA rules. The background research of aircrafts in existing category has been made in the market. The concept, with whom this thesis deals with, has been projected thanks to this analysis. The second part of the thesis is focused on avionics equipments of aircrafts. Market analysis has been made and the way of medernizing small sports airfts' equipment in categories UL and LSA has been projected.

Návrh a analýza vlastností hydraulického servomechanismu řízení malého a rychlého letounu / Design and analysis of the properties of the hydraulic servo control of a small and speedy aircraft

Cäsar, Tomáš January 2017 (has links)
Target of this thesis was to design servo-mechanism suitable for control system of small and speedy aircraft, such as business jets and light multi-purpose attack aircraft. Main task was to use suggested characteristics for computer analysis and determine impact of their changes on servo-mechanism properties. Further on, experimental way of determining these parameters.
