Dear colleagues,

We are renewing our invitation for participants in

The Fifth International Summer School on Screw-Theory Based Methods in 

3 -- 11 September 2014

University of Bologna, Bologna, Italy


In the short time since our first call, we have received many 
registrations. A limited number of places is still available, so we urge 
those who wish to participate to register without delay. The deadline is 
June 30, 2014.

For its fifth edition, our summer school on screw theory comes to the 
world's oldest university: Bologna's Alma Mater Studiorum.
The enthusiastic feedback from each of the first four very successful 
Summer Screws events (in Genoa, Italy, in Shanghai, China, again in 
Genoa, and in Florianopolis, Brazil) proves that this initiative 
continues to provide a service that the robotics community values.

Summer Screws 2014 will gather six experts in the robotics applications 
of screw theory and up to 40 participants at the University of Bologna 
from 3 to 11 September.
The School will teach attendees how to apply existing methods and 
empower them to develop new ones in their own research.
The basic theoretical notions will be introduced in a rigorous manner, 
with emphasis on examples, applications, and exercises.

The main topics will be:

1. Basic vector-space properties of twists and wrenches: physical 
interpretation of the linear operations; linear dependence and 
independence, subspaces; bases and coordinates. (Lecturer: Dimiter 

2. Scalar products, dual spaces, reciprocity. Constraint and freedom in 
mechanisms. Constraint analysis, type synthesis of single-loop 
mechanisms, type synthesis of parallel manipulators. (Lecturer: Xianwen 

3. Velocity and singularity analysis of parallel and 
interconnected-chain mechanisms. Derivation of input-output velocity 
equations and singularity conditions. (Lecturers: Matteo Zoppi and 
Dimiter Zlatanov)

4. Mappings between screw spaces, stiffness and inertia. Structure of 
robot compliance. Eigenvalue problems and eigenscrews. Synthesis with 
springs. (Lecturer: Harvey Lipkin)

5. 6D formulation of the dynamics of individual rigid bodies and 
rigid-body systems. Equations of motion. Dynamics algorithms. (Lecturer: 
Roy Featherstone)

6. Basic Lie-group theory, matrix representations of the group of 
rigid-body displacements. Lie algebras as related to screw theory. The 
exponential map and its applications in modern robotics. (Lecturer: Jon 

Marco Carricato will be this year's invited lecturer, with a talk about 
persistent screw systems.

Up to 40 registrations are accepted at the price of 300 Euro, no later 
than 30 June, 2014.

University of Bologna's Summer Screws site.

Summer Screws 2014 is organized by the Group of Robotics and Articular 
Biomechanics (GRAB), at the Department of Industrial Engineering of the 
University of Bologna, Italy, and the Laboratory of Design and 
Measurement for Automation and Robotics (PMAR), at the Department of 
Mechanical, Energy, Industrial, and Transport Engineering of the 
University of Genoa, Italy.
It is endorsed by IFToMM, the Robotics and Automation Society of the 
IEEE, the Italian Robotics and Automation Association (SIRI), the 
Bologna Society of Engineers, and the City of Bologna.
We gratefully acknowledge the financial support of IMA Industries, the 
Department of Industrial Engineering and the School of Engineering and 
Architecture of the University of Bologna, as well as of the IFToMM 
Young Delegates Program.
