The autonomous trajectory tracking control includes dynamic simulation according to object surface and depth measurement. The robot is equipped with three independent driven omnidirectional wheels and six ultrasonic sensors. The Jacobian between Cartesian space with respect to the joint space is setup for ellipse motion planning so that it not only can autonomously follow the prespecifled trajectory tracking but also avoid obstacles. An architecture is setup to split computation between the remote cloud and the robots so that the robots can interact with the computing cloud. Given this robot/cloud architecture, the stability of the closed loop control system using the predictive control algorithm is guaranteed with satisfactory tracking performance on the cloud during a periodically updated preprocessing phase, and manipulation queries on the robots given changes in the workspace can achieve real time trajectory tracking and obstacle avoidance. Finally, experiments are given to validate the path tracking performance and computational efficiency.","PeriodicalId":282633,"journal":{"name":"2018 International Automatic Control Conference (CACS)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, this paper proposes to apply Reinforcement Learning (RL) to resolve an automated assembly task based on 3D point cloud data. To address this task, the proposed structure is separated into 2 stages including registration stage and assembly path planning stage. Firstly, in the registration stage, one of the objects is matched to an assembled model to determine the transformation between two 3D point clouds by using RANdom Sample Consensus (RANSAC) and Iterative Closet Point (ICP). Secondly, we employ Q-learning method to train a model to make optimal decisions in assemble path planning task. The entire optimized assembly path planning task has been successfully accomplished for typical objects. Finally, the performance of the approach developed in this paper has been validated by experiments.","PeriodicalId":282633,"journal":{"name":"2018 International Automatic Control Conference (CACS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129355074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practice, most servomotors use the encoder to measure the position of the motor and then use the conventional differential algorithm, dividing the displacement between two sampling points by the sampling time, to obtain the velocity for feedback control. However, this way can result in serious noise amplification. In this study, velocity estimators are used to solve this problem. This paper compares three velocity estimators including PI Servo-loop velocity estimator, Levant differentiator, and Kalman filter. First, MATLAB/Simulink are used to simulate these velocity estimation algorithms. For further validation, these velocity estimation algorithms are simulated and tested with the actual motor position signals. In experiments, the estimators are implemented on a digital signal processor (TMS320F28335) from Texas Instruments. As a result, the Kalman filter outperforms the other velocity estimators in velocity control.","PeriodicalId":282633,"journal":{"name":"2018 International Automatic Control Conference (CACS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121216232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are some basic movements to navigate following the wall, such as walking, avoiding obstacles, and following walls or corridors.

The actor-critic reinforcement learning progress is similar to the produce of dopamine in human brain and the mechanism which acts on the motoneuron, which dopamine enhances specific actions by reinforce the synaptic contact of the frontal lobe. As same as artificial intelligence (AI), it means the reward signal of dopamine in the neural network can be used to adjust weights in artificial neural which makes the system find the right way to solve the work. The actor-critic scheme is applied to solve the dynamic programming equation problem, using actor and critic neural networks (NNs) for solving optimal controller and optimal value function, respectively. The weights of actor and critic NNs are updated using policy gradient and recursive least squares temporal-difference learning (RLS-TD) scheme at each sampling instant.

Most of the hardware components used in this system are available off the shelf, and the idea is to develop a cost-effective localization system for mobile robot tests. The embedded vision system computes fiducial feature detecting algorithm and the pose estimation results are sent through pre-synchronized distributed modules to the server. The server then retrieves the object pose by using the proposed observation decision algorithm. A glitch elimination method is applied to deal with the problems of none observation of all cameras or when the current pose data is far from the previous ones.
