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 . You can download the rob
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 are not part of a domain. The
only requirement is that you need to have the same user account on both the
server and client, plus I’m going to assume the passwords match on both
systems.
On the
server (Hyper-V 2012):
Execute
“cscript hvremote.wsf /add:accountname” (replace accountnamewith you account
name).
On the
client (Windows 8.1) you need to run a command prompt as Administrator, then
execute
cscript
hvremote.wsf /anondcom:grant
Once done
go back to Hyper-V Manager, right-click on the server and choose Refresh. It
should now be able to connect to the server.
