I just got an email from Studica, which I have used to buy software. Now they are selling their own branded robotics kit, which looks to be a mix of omni- and mecanum wheels and beams I have seen elsewhere. Of course they promise they are the "best", just like everyone else. There are so many kits and systems and controllers and languages that it's getting hard to keep up. Mostly a good problem to have, I suppose. Educational toys have been selling like wildfire during the pandemic.
