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
If you wish to copy an entire hard drive to another hard drive (i.e. clone) you can use the standard "dd" program available on almost any Linux distribution. A good reason for cloning would be to move all data from a spinning disk to an SSD disk, but in theory it could be anything that acts as a block device, even a file (e.g. allowing you to write all contents from a disk to a single file, and vice versa). I'm usually using SliTaz because it's a lightweight Linux distribution allowing for fast boot times, normally under 5 seconds when you use the SliTaz base Live option. So here is the steps I'm following: Connect both hard drives to the same PC. Boot from SliTaz USB drive & choose the SliTaz base Live option. Login as root with password root. Execute "dmesg | grep sd" to see all hard drives connected to the system. You'll need to verify the source & destination disk. Once you've identified the source disk (input file) and de
