FLL EV3 Robot

This blog post is about our current EV3 robot we're planning to use in the 2023/2024 FLL competition. Some features: 2 large motors for steering. 2 medium motors for attachments.  2 colour sensors for picking up the white and black lines, also used for line squaring. 1 gyro sensor. To enable attachments to be changed as quickly as possible we're using gravity to keep the gears connected, i.e. you don't need to fasten anything to the robot. Every attachment has 2x 12 tooth double bevel gear (part 32270) which comes in contact with the 2x 20 tooth double bevel gears (part 32269) on the robot. The medium motors are horizontally aligned on the robots, but we use 12 tooth double bevel gears to convert that to vertical alignments. These in turn are connected to 20 tooth double bevel gears, and the attachments in turn connect to these 20 tooth double bevel gears with their 12 tooth double bevel gears.  The complete robot is modelled in Bricklink Studio 2 .

Connect from Windows 8.1 to Hyper-V 2012 Server using Hyper-V Manager

Let’s assume you have a HyperV 2012 server available and trying to connect to it from a Windows 8.1 machine. First you need to install the Hyper-V Manager tool. Go to Control Panel – Programs – Programs & Features – Turn Windows features on or off. Expand Hyper-V and select Hyper-V Management Tools. Once installed run Hyper-V Manager and click on Connect to Server… Specify your server name or IP address (in my case it’s HYPERV2012) and click on OK. It will try to connect but give you the following error: Access denied. Unable to establish communication between ‘HYPERV2012’ and ‘WIN81’. To help in setting up a connection there is a nice tool available from https://code.msdn.microsoft.com/windowsdesktop/Hyper-V-Remote-Management-26d127c6 . You need to download hvremote.wsf (it’s a Windows Script File) and run it on both the server & the client. There are various options between server and/or client on a domain, but in this example I’ll assume both ar

Install & configure Hyper-V Server 2012 R2

Hyper-V Server 2012 is a free edition of Server 2012 with fully functional Hyper-V capabilities. It excludes the GUI from the server edition, but you can administer the box from any external computer running Windows 7 or higher. It’s also possible to enable file sharing, implying the server can act as a backup machine. In addition it’s possible to install third party software which will give you a GUI-like experience at no cost.  First you need the Hyper-V 2012 ISO which can be downloaded at https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2012-r2. You’ll need to register before you can download. After downloading you’ll need to write this ISO either to a DVD or USB drive. For both options you can use the Windows USB/DVD download tool available at https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool. Boot your server with this ISO and you’ll get the following screen: Click Next and on Install Now. You’ll have to accept the license terms.
