Imagine a robot sitting on the upper left hand corner of an nxn grid the robot can only move in two directions ctions: right and down how many possible paths are there for the robot? A robot can only go down or to the right in the upper left corner of a nxn square. How many paths are there in the lower right corner?

The algorithm of industrial robot is divided into perceptual algorithm and control algorithm, further subdivided into environment-aware algorithm, path planning and Behavior decision algorithm (AI), motion control algorithm, and the latter two can be collectively referred to as control algorithm Environment-aware algorithm obtains the environment various data (robot vision and image recognition), locates t

"Deyang-made" water intelligent cleaning robot in the work. Zhou photo -Wang Shanshan newspaper reporter Rei On the morning of December 19, near the Deyang Deyang, a giant "goldfish" is slowly swimming to swim, the nearby aquatic waste is constantly eaten by it. Originally, this is a "Deyang-made" water intelligent cleaning robot. That morning, experts from the National Ministry of Water resources were id

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
