Abstract The transmission error characteristics of a stepping motor drive timing belt system are investigated theoretically and experimentally for the fixed and the automatic tensioner. It is found that the amplitude of the transmission error θe due to the pulley eccentricity and θm due to the stepping motor torque variation decrease as the belt tension increases and the applied torque load increases. Also, θe can be reduced by using the automatic tensioner, while θm shows almost same magnitude for both tensioners. The theoretical results based on the bondgraph model are in good accordance with the experimental results.

Automated storage and retrieval warehouse systems (ASRS) have been implemented in industrial for few decades. This kind of combination of project has become common in current industry field. Refer to Pa. Pittsburgh, the enhancement of ASRS has helped to improve optimal stock capacity in limited space and minimize process flow time. The purpose of this project is to design a hardware prototype that can fulfill the concept of ASRS and can be implemented at electronic components store that requires store management. This is to improve the process in stock checking and also store or retrieve item. Furthermore, there have several major parts that can be considered to use this hardware such as method of store and retrieve, storage structure, movement of the machine and machine travelling system. The timing belt system is implemented on this hardware for performing linear X-Y-Z motions. Besides, the concept of pallets supported rack had been implemented in storage structure design. Last but not least, the concept of an automated guided machine travels to the desired location on rack is selected as a store and retrieve method for this hardware.

The introduction of automated L5 driving technologies will revolutionise the design of vehicle interiors and seating configurations, improving occupant comfort and experience. It is foreseen that pre-crash emergency braking and swerving manoeuvres will affect occupant posture, which could lead to an interaction with a deploying airbag. This research addresses the urgent safety need of defining the occupant’s kinematics envelope during that pre-crash phase, considering rotated seat arrangements and different seatbelt configurations. The research used two different sets of volunteer tests experiencing L5 vehicle manoeuvres, based in the first instance on 22 50th percentile fit males wearing a lap-belt (OM4IS), while the other dataset is based on 87 volunteers with a BMI range of 19 to 67 kg/m2 wearing a 3-point belt (UMTRI). Unique biomechanics kinematics corridors were then defined, as a function of belt configuration and vehicle manoeuvre, to calibrate an Active Human Model (AHM) using a multi-objective optimisation coupled with a Correlation and Analysis (CORA) rating. The research improved the AHM omnidirectional kinematics response over current state of the art in a generic lap-belted environment. The AHM was then tested in a rotated seating arrangement under extreme braking, highlighting that maximum lateral and frontal motions are comparable, independent of the belt system, while the asymmetry of the 3-point belt increased the occupant’s motion towards the seatbelt buckle. It was observed that the frontal occupant kinematics decrease by 200 mm compared to a lap-belted configuration. This improved omnidirectional AHM is the first step towards designing safer future L5 vehicle interiors.

Abstract Inspired by gecko’s adhesive feet, a wheeled wall climbing robot is designed in this paper with the synchronized gears and belt system acting as the wheels by considering both motion efficiency and adhesive capability. Adhesion of wheels is obtained by the bio-inspired adhesive material wrapping on the outer surface of wheels. A ducted fan mounted on the back of the robot supplies thrust force for the adhesive material to generate normal and shear adhesion force whilemoving on vertical surfaces. Experimental verification of robot climbing on vertical flat surface was carried out. The stability and the effect of structure design parameters were analyzed.

Over Time

Net pasture production has been monitored over time on an on-going Pinus radiata-pasture agroforestry experiment located at Carngham, Victoria. Established in 1983 by thinning a 2-year-old plantation, the study contains five treatments (systems): open pasture (no trees), 60 trees/ha, 200 trees/ha wide-spaced, 200 trees/ha 5-row belt and 1360 trees/ha. Net pasture production was only weakly affected by the proximity of trees in the 60 trees/ha and 200 trees/ha wide-spaced systems. However, in the 200 trees/ha 5-row belt system, pasture production was often significantly less within the tree zone and at 1.5 m from the tree edge compared with production at 10.5 m from the tree edge. While there was a trend for greater pasture production at 10.5 m and 18 m from the tree line than occurred in the open pasture system, the width of pasture adjacent to the 5-row belts was too narrow (36 m) to demonstrate any shelter benefit on pasture production. From 1990 to 1992, pasture production (kg ha-1) for each system was similar, although production tended to decrease with increasing tree stocking. Following the cessation of pruning (1992), pasture production was significantly reduced by increased tree stocking, such that pasture production in the 200 trees/ha wide-spaced and 200 trees/ha 5-row belt systems was 60% and 69% and 23% and 67% of open pasture in 1993 and 1994 respectively.
