Pose-Constrained Path Optimization for Manipulators with Contact Feedback from Sparse Waypoints
RoboticsConventional robot motion teaching methods are time-consuming and place a significant burden on operators, especially when trajectory modification is required after contact with the environment.

Comparing the paths of Hedgehog release in artificial and natural settings
FEBS Letters, EarlyView.Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

Path Generation, Control, and Monitoring
, 2020 A critical issue in additive manufacturing (AM) is the control of the printer actuators such that the deposition of material (or a few different materials) takes place in an organized way. Typically, the actuators are connected with a low-level controller that can receive computer numerical control (CNC) instruction. A 3D printer controller is, usually,

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Path Generation for Industrial Robots
, 2003 Path generation in Cartesian space is discussed and the idea of using lines and arcs to create general paths is presented. To make smooth paths in Cartesian space zones are introduced and two different ways to interpolate zones are given.
