Abstract For industrial applications, truss robots can perform mutipleoperations, such as transporting objects and handling tools independently, but face the challenges of inconvenient disassembly non-recyclability. Therefore, a robot load-bearing module based on spatial bar structure is designed, which consists bars connectors. Ansys Workbench used for static analysis beam. The results show th...

Sorghum seedling transplanting is an essential agricultural activity in Sub-Saharan Africa. However, conventional manual of sorghum a time-consuming, labour-intensive, costly with low rate, uneven plant distribution, and degree accuracy. In order to realize rapid precise seedlings transplanting, duckbill-type mechanism has been designed. This five-bar linkage consisting two crankshafts, connect...

The availability of new accurate radio flux densities of Jupiter in and around the λ1.3 cm ammonia absorption band, one from groundbased radio data and five from the WMAP satellite, permits reexamination of the structure of the Jovian upper troposphere. These flux densities, with accuracies of 1–3%, indicate that the Jovian atmospheric ammonia is globally subsaturated within and above the ammon...

This paper presents the design and analysis of a reduced degree-of-freedom Robotic Modular Leg (RML) mechanism used to construct a quadruped robot. This mechanism enables the robot to perform forward and steering locomotion with fewer actuators than conventional quadruped robots. The RML is composed of a double four-bar mechanism that maintains foot orientation parallel to the base and decouple...

This paper presents a new formulation of the artificial potential approach to the obstacle avoidance problem for a mobile robot or a manipulator in a known environment. Previous formulations of artificial potentials, for obstacle avoidance, have exhibited local minima in a cluttered environment. To build an artificial potential field, we use harmonic functions which completely eliminate local m...

mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some...

We propose a new horizontal locomotion model to describe the motion of an eight-legged bio-inspired miniature robot. The model does not include compliance, and can capture the kinematics of the observed locomotion behavior that corresponds to an alternating tetrapod gait. We exploit symmetries and synergies to reduce the eight-legged robot to a mechanism that is composed by two switching four-b...
