Cover Story: Human handwriting is an everyday task performed regularly by most people. In robotic painting, multiple calligraphy machines exist that were built to replicate some aspects of human artistic writing; however, most projects are limited to a specific style of handwriting. Our method allows industrial robots to write text in arbitrary typefaces and scripts using paintbrushes. We extract brushstrokes from glyphs and optimize the trajectories using a brush model. Our model computes brush pressure and accounts for brush lag. The model is automatically acquired from calibration strokes. Our method generates trajectories for text in any given typeface, which, when executed by a robotic arm, results in legible written text. We can render most writing systems, excluding emoji and ligatures, in which arbitrary texts can be written. View this paper

Non-Commutative Logic for Collective Decision-Making with Perception Bias

  • Evgeny Kagan,
  • Alexander Novoselsky,
  • Daria Ramon and
  • Alexander Rybalov

In this paper, we suggest an implementation of non-commutative logic and apply its operators for decision-making in a group of autonomous agents. The suggested operators extend the uninorm and absorbing norm aggregators and use an additional asymmetr...
