Novel magnetic carbonaceous bio-char was hydrothermal prepared from microalgae under different loadings of iron and its structures and surface chemistry were characterized with Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and nitrogen adsorption-desorption isotherm (BET). The morphology of bio-char changed from sheet to particle as...
Trajectory prediction plays a very important role in the process of playing table tennis for robot. Its accuracy determines whether the striking action will succeed or not. This paper first analyzes how the spinning influences the flight model and the rebound model for the table tennis robot. Two models are designed for spinning balls. Meantime, it indicates that the offset on y axis is related to...
With two auxiliary lines drawn on the racket pad, the intersections of the auxiliary lines and the pad edge are selected as feature points. A simple pose measurement method is designed based on the feature points. A high efficient image-processing algorithm and a feature points extracting method are proposed according to the characteristics of the pad and the auxiliary lines. The racket pose in the...
