the intelligent control of walking of humanoid robots is one of the key research directions in the field of robotics research, but the traditional motion model's constraint on the center of mass makes it difficult for robots to maintain walking stability and simulate human gait at the same time for its excessive attention on stability. Compared withthe traditional deep reinforcement learning algorithm, the DDPG algorithm has the ability to handle continuous action space and high-dimensional state space, and has a wide application prospect in many practical problems. We proposed a bipedal robot control method based on reward function optimization to enable the robot to achieve both stable high-speed movement and human gait imitation. this paper combines the physical characteristics of the bipedal robot to establish a control system based on the DDPG algorithm. At the same time, the reward function is designed to guide the robot to learn the correct walking strategy. through the comparative test, the weight limit ratio of each reward function for the bipedal robot to stably increase the speed is given. the simulation results show that the method proposed in this paper has good practicality and effectiveness.

Depth Completion focuses on creating an accurate, dense, pixel-wise depth from sparse depth. Prior approaches utilized RGB images as guides and applied spatial propagation to refine initial dense depth maps. However, these methods are constrained by limited receptive fields. they require multiple iterations for full image depth propagation. the large number of parameters and iterations hinders practical applications. To overcome these limitations, this paper presents a Multi-scale Convolutional Spatial Propagation Network. this network effectively broadens the iterative refinement's receptive field and introduces an adaptive neighborhood propagation. Firstly, it performs iterative refinement on multi-scaled depth maps, scaling the receptive field accordingly. Secondly, we introduce an innovative neighborhood selection strategy. this strategy reduces the computational complexity associated with expanding neighborhoods. Additionally, this method introduces direction-aware affinity normalization. During the propagation phase, it adaptively adjusts affinity. this preserves object boundary sharpness. Extensive tests conducted on the NYU Depth v2 dataset confirm the effectiveness of our approach. Compared to other SPN-based methods, our approach achieves efficient neighborhood propagation, and requires only three iterations to produce detailed dense depth maps.
