With the development of technology and the reduction of cost, the field of robot, unmanned aerial vehicle and unmanned driving has become an important application field of LiDAR in the field of laser radar. There are many kinds of sensors in the field of robotics, including cameras, lidar, millimeter-wave radar, ultrasound, infrared and many other sensors. The features and advantages of each sensor are not the same. The sensor sounds iffy, and many co

Introduction to the first chapter 1.1 Uncertainties in roboticsRobots must be able to accept a large number of uncertainties in the objective world. There are many factors that cause the robot to be uncertain:Robot environmentSensorActuator of the robotRobot softwareApproximate algorithm1.2 Probabilistic RoboticsProbabilistic Robotics focuses on the uncertainty of robot perception and behavior. The main id

Label:The Robot Framework provides a variety of library libraries. Where the database library can be used to connect operational databases. 1. Installing the database Library Open the Robot framework website, find the database library, the official website provides Java and Python two version of the database library, here I use the Python version, the address is http://franz-see.github.io/Robotframework-Dat

lambda obtained from 17, the whole sample is used as the training sample. Calculate Ein,eout(2) Answer: Ein = 0.035 eout=0.0219-20: The question of 第19-20(1) Test instructions: 19. Divide the sample into 5 parts, calculate the ECV by the method of cross-validation, calculate the minimum ecv20. Calculate ein,eout with the corresponding lambda value for the minimum ecv obtained by 19(2) Answer: 19. Log=-8, Eval = 0.0320.Ein = 0.015.

the raspberry pie on the processing of images, can also be sent after the computer processing. Since the final requirement of this project is for the robot to run independently, it is recommended that most of the processing be done on the raspberry pie, which should consider performance issues. Although the raspberry pie can use haarcascade face recognition or human body recognition (upper torso), but the performance is not enough, can reach a lower

We're going to go ahead. ROS Learning Series--using URDF to create a robot model in Rviz one of the 3D observation link uses continue to create a two-wheeled trolley with four wheels to rotate. A set of joint that can rotate 1. Change the joint type to "continuous" so front_left relative base_link is a rotating device 2. The position of rotation is defined by the origin, which defines the new origin of the Tyer_front_left, which is the origin of t
