Atommann, Awesome. I always thought that opensource means I can study the source code. The Chinese commands do really work via Bluetooth? Way cool.
More of that, I like it :=) :=) Matthias PS: hmm. There are languages that use a right-to-left direction for ... symbols (IIRC Arab). A nice challenge, now ;) Am Dienstag, den 20.10.2015, 11:15 +0800 schrieb Atommann: > Hi, > > About two weeks ago I met a pretty lady in our office, she told me > there is a Hackathon hold by their company and Shenzhen Graduate > School of HIT [link 2]. > > At the first moment I have no idea to build what. > > Me: "What's the topic?" > The pretty lady: "Robots" > Me: "Good topic!
