Path restriction and speed regulation via force feedback-type welding teaching device using magnetorheological brakes

There are two types of bilateral servo mechanisms utilized in force reaction type manipulators. The simple symmetry type has the larger transfer deviation. The force feedback type with the smaller transfer deviation requires troublesome force sensing devices. This paper describes a simple compensation method of transfer deviation on the symmetry-type. We found that transfer deviation of the torque decreases by means of subtracting tachometer generator output through a PD circuit from the driving input of the opposite motor. The system is unstable when the gain constants in compensation circuits are over the limits, which are determined as equivalent mechanical inertia moment and viscous damping factor. The transfer deviation of the compensated symmetry type system is near to that of the force feedback system.

The Impact

For the effective use of modern tools, the inherent visuo-motor transformation needs to be mastered. The successful adjustment to and learning of these transformations crucially depends on practice conditions, particularly on the type of visual feedback during practice. Here, a review about empirical research exploring the influence of continuous and terminal visual feedback during practice on the mastery of visuo-motor transformations is provided. Two studies investigating the impact of the type of visual feedback on either direction-dependent visuo-motor gains or the complex visuo-motor transformation of a virtual two-sided lever are presented in more detail. The findings of these studies indicate that the continuous availability of visual feedback supports performance when closed-loop control is possible, but impairs performance when visual input is no longer available. Different approaches to explain these performance differences due to the type of visual feedback during practice are considered. For example, these differences could reflect a process of re-optimization of motor planning in a novel environment or represent effects of the specificity of practice. Furthermore, differences in the allocation of attention during movements with terminal and continuous visual feedback could account for the observed differences.

Insect Attack

Rattan on frequently attacked by the powder post beetle (Tellu, 2001). The prevention of dry powder attacks is done by preservation. The increasing resistant of rattan from insect attack can be done by an environmentally friendly preservative, the Galam wood vinegar. This research aims to determine the most effective concentration of preservative that shows the lowest attacks level of D. Farb minutus powder. The rattan used is green rattan (Calamus sp.) The concentration of preservative that are used:10%, 40%, 70% and 100%. The testing of dry powder attack used force feedback method. The effectiveness test parameters of wood vinegar to dry powder attacks included degree of protection Dinoderus minutus Farb. powder, reduction percentage of rattan weight and the mortality of dry powder Dinoderus sp for toxicological testing of wood vinegar. The test results showed that the degree of protection powder in rattan growing along with the increased concentration of preservatives. The higher the concentration of wood vinegar, the smaller the reduction of rattan weight and the higher the mortality rate of dry powder. Keywords: resistant of rattan, wood vinegar, Dinoderus minutus.
