Aiming at the problems of poor passing capacity machines and low cleaning rate seed strip during wheat no-tillage sowing in annual double cropping areas North China, a spiral discharge anti-blocking row-sorting device (SDARD) was designed is reported this paper. After straw cut chopped by high-velocity rotating no-till knife group (NAKG), thrown into discharging mechanism (SDM) behind NAKG. The...

We discuss a speed controller for a hopping robot with a pneumatically powered leg. The controller uses a neural network to model the neutral point as a function of running speed and hopping height. The network is trained off-line using training data taken from a simulated hopper that is manually controlled by a human. Simulation experiments of hopping in the sagittal plane show improved perfor...

Particle algorithms are becoming a standard tool for the dynamical simulation of granular flows. An overview of the standard techniques is given along with a discussion of their suitability for multi-processor machines of the vector or scaler type. In particular, the issues surrounding efficiency and load-balancing are discussed. Furthermore, two examples illustrating the potential uses of such...
