Printing Techniques

As 3D printing technology becomes more ubiquitous and pervasive, printed robot structures are likely to become popular. However, these 3D printed structures have inherent flexibility which causes link deflections and vibrations that lead to difficulties in maintaining gait and produce instabilities during motion. In this paper a biped robot, realized with 3D printing techniques, was modeled and its gait was simulated under position control. Spring and damper elements are used within powered joints to model the link flexibility. Servos were placed at the joints and an open-loop gait trajectory was executed by posing the robot through a series of servo angles. The gait of the printed robot was designed using the model. The printed robot’s stability and accelerations during the motion were characterized with 3-axis accelerometers and gyroscopes mounted on the robot. The acceleration measurements from the printed robot are then compared with the model behavior.

Abstract Bayesian decision theory provides a simple formal elucidation of some of the ways that representation and representational abstraction are involved with, and exploit, both prediction and its rather distant cousin, predictive coding. Both model-free and model-based methods are involved.

The extracellular matrix (ECM) plays a critical role in directing cell behaviour and morphogenesis by regulating gene expression and nuclear organization. Using non-malignant (S1) human mammary epithelial cells (HMECs), it was previously shown that ECM-induced morphogenesis is accompanied by the redistribution of nuclear mitotic apparatus (NuMA) protein from a diffuse pattern in proliferating cells, to a multi-focal pattern as HMECs growth arrested and completed morphogenesis . A process taking 10 to 14 days.To further investigate the link between NuMA distribution and the growth stage of HMECs, we have investigated the distribution of NuMA in non-malignant S1 cells and their malignant, T4, counter-part using a novel model-based image analysis technique. This technique, based on a multi-scale Gaussian blur analysis (Figure 1), quantifies the size of punctate features in an image. Cells were cultured in the presence and absence of a reconstituted basement membrane (rBM) and imaged in 3D using confocal microscopy, for fluorescently labeled monoclonal antibodies to NuMA (fαNuMA) and fluorescently labeled total DNA.
