Kurs Programmirovaniya Lego Mindstorms Ev3 Robota V Srede Ev3

• In this model, we will read the Accelrometer on-board Sense HAT. We will determine the motor speeds for the EV3 robot by using the acceleration data read from the Sense HAT Accelrometer. A network connection would be setup between the Raspberry Pi device and the EV3 robot for data exchange. • In this model, we would use the communication blocks of LEGO MINDSTORMS EV3 to recieve the data sent by Raspberry Pi. The data received will be used to drive the motors of the EV3 robot. This example would help you learn the following. Working Principle of Robot movement control In this section, we will discuss how the acceleration data can be used to control the movement of the robot.

The 'pitch' and 'roll' value corresponding to a given position of Sense HAT can be mathematically determined from the accelaration measured from the Accelerometer on-board Sense HAT. We map the 'pitch' and 'roll' movement of the Sense HAT to the movement of the EV3 robot. The 'pitch' would represent the forward and reverse movement of the motor whereas the 'roll' would represent the sideward movement of the robot. The mathematical equations required to convert the 'pitch' and 'roll' values to linear speed of the robot are realized using a MATLAB function block in the Simulink model for configured for Raspberry Pi. A communication link for data exchange is set up between Raspberry Pi and the EV3 brick. The linear motor speed derived from the pitch and roll values is sent over UDP from Raspberry Pi to EV3.

EV3 will receive this data and use it as input to drive the two motors. Task 1 - Familiarize with Controlling EV3 using Host model example shows usage of Dashboard widgets in a Simulink model running on a Host machine to control the movement of a EV3 robot. The communication between EV3 and the Host is over UDP. Complete this example to get familiarity with setting up a communication link between EV3 and a Host model for data exchange. Task 2 - Install Simulink Support Package for Raspberry Pi You need Simulink Support Package for Raspberry Pi to run Simulink model on Raspberry Pi hardware.

Install Simulink Support Package for Raspberry Pi. Click the link to 2. Complete the example in Simulink Support Package for Raspberry Pi you just installed. Task 3 - Familiarize with Sense HAT Accelerometer example shows usage of the Accelerometer on the Raspberry Pi Sense HAT. The acceleration data is used to auto-rotate an image displayed on the LED matrix of Sense HAT.

Complete this example to get familiarity with the usage of Accelerometer. Task 4 - Set up LEGO MINDSTORMS EV3 robot In this task, we will build a EV3 robot and connect the EV3 brick to the same network as the Host PC. Build a two-wheeled robot. You can build a robot similar to the one described in the printed building instructions in the education core set. Set up a connection between EV3 brick and your host machine. Please refer to Task 1 and 2 in example.

Programma rascheta objema zhidkosti v emkosti. Reminds me of the Nazis: The Jews are the evil capitalist bankers, AND, they are the Russian communists!

Here is a plain side view: Here is a picture from above of the bolt/reciever: Here is near the end of the barrel, where the bayonett attaches: A closeup of the bolt/surrounding area: Here is the Mauser logo that is on top of the reciever, right where the bolt slides into the barrel: This is the left-hand side of the reciever, right behind the rear-sight. You can see the eagle/swastika, but it is a bit worn. Alright, here are the pictures with descriptions! EDIT: I can post pics if needed. Mauser serial numbers k98. There is also a weird 'u' type logo, and I fuzzed out part of the serial number: This is also on the left-hand side of the reciever, down from where the Mauser logo is.

Task 4 - Configure Network Connection In this task, you will set up network connection between Raspberry Pi board and LEGO MINDSTORMS EV3. The communication protocol used in this example is UDP. Connect Raspberry Pi board to the network with Ethernet cable through Ethernet port. Make sure that both the Raspberry Pi board, Host PC and the EV3 robot are connected to the same network. Verify the connection between your Raspberry Pi board and LEGO MINDSTORMS EV3.
