W artykule przedstawiono program badawczy mający na celu wstępne określenie potencjału technologii iPAD-LiDAR w inwentaryzacji obiektów budowlanych.
Autorzy skupili się na wykorzystaniu komercyjnie dostępnych urządzeń (telefonów komórkowych
i tabletów) wyposażonych w sensor LiDAR. Urządzenia takie można potraktować jako nisko kosztowe aparaty pomiarowe i zastosować do pomiarów inżynierskich. Pierwszym możliwym obszarem wykorzystania omawianych urządzeń są szeroko rozumiane inwentaryzacje budowlane, które przy wykonywaniu ich tradycyjnymi metodami zawsze wiążą się z dużym
nakładem pracy. Automatyzacja tego procesu oraz jakość i ilość danych pozyskanych przy
wykonywaniu inwentaryzacji tworzy zupełnie nową rzeczywistość techniczną i związane z tym
możliwości pomiarowo-diagnostyczne.

Extremely Modular System (EMS) is a relatively new concept introduced a few years ago. It represents a new approach to the design of engineering structures and architectural objects where assembly of congruent units allows for the creation of free-form shapes. The main difference from the traditional modular systems used in engineering, is the emphasis of the minimal diversity of types of modules, ideally - just one. This is why these system are called "extremely" modular. One of the most natural areas for use of EMSs are deployable structures. This paper presents rigid body folding mechanisms for two selected EMSs: Pipe-Z - a parametric system comprised of one type of module allowing for creation of three-dimensional knots, and Truss-Z - a modular system for creating free-form ramps and ramp networks among any number of terminals.

Extremely Modular System (EMS for short) is a relatively new concept introduced by the
author a few years ago. It represents a new approach to the design of engineering
structures and architectural objects where assembly of congruent units allows for the
creation of free-form shapes.
The main difference from the traditional modular systems used in engineering, is the
emphasis of the minimal diversity of types of modules, ideally - just one. This is why these
system are extremely modular.

These are six basic advantages of EMSs:
1. Economical - as they are suitable for mass fabrication, thus lowering the cost so they
can be broadly applied;
2. Functional - as they allow for reconfiguration, expansion, reduction;
3. Robust - since every module which failed can be easily replaced with an identical but functional one;
4. Discrete - as they are suitable for intelligent mathematical modeling, and their configurations can be subjected to discrete (multi-objective) optimization using efficient search algorithms;
5. Uniform - this feature is advantageous for rapid deployment and automated assembly.
6. Sustainable - as the entire modules can be reused.

One of the most advantageous areas for implementation of EMSs are deployable structures.
Moreover, it is crucial that the individual modules and entire structure are rigid.
This paper presents folding mechanisms for two selected EMSs: Pipe-Z - a parametric system
comprised of one type of module allowing for creation of three-dimensional knots, and Truss-Z -
a modular system for creating free-form ramps and ramp networks among any number of
terminals.
