Lessons learned from a prediction and postdiction of a shake table test on an unreinforced masonry aggregate

Katrin Beyer, Igor Tomic

Historical centers of Europe and Croatia are often formed by unreinforced masonry building aggregates that developed as the layout of the city or village was densified. In these aggregates, adjacent buildings can share structural walls with an older and a ...

drozBot: Using Ergodic Control to Draw Portraits

Sylvain Calinon

We present drozBot: le robot portraitiste, a robotic system that draws artistic portraits of people. The input images for the portrait are taken interactively by the robot itself. We formulate the problem of drawing portraits as a problem of coverage which ...

Graphical details: the secret life of Christopher Wren's drawing of the weather clock

Ion-Gabriel Mihailescu

Historians have unanimously credited Christopher Wren with having constructed a weather clock (a self-registering instrument) in the early 1660s. This conclusion was based on the account of the French diplomat Balthasar de Monconys, which included a sketch ...

Benchmark for Bimanual Robotic Manipulation of Semi-deformable Objects

Aude Billard, Kunpeng Yao, Farshad Khadivar, Bernardo Fichera, Konstantinos Chatzilygeroudis, Ilaria Lauzana

We propose a new benchmarking protocol to evaluate algorithms for bimanual robotic manipulation semi-deformable objects. The benchmark is inspired from two real-world applications: (a) watchmaking craftsmanship, and (b) belt assembly in automobile engines. ...
