EV3-PD Protocol Droid

[MajorAlvega]

This was one of those crazy ideas we have when are discussing with other LUG fellows.

This guy from PLUG defied me to show a LEGO robot that translates conversation, much like the C3PO protocol droid from Star Wars. As usual, he wasn't really expecting ti could be possible with LEGO.

I only had a couple of hours so I decided to copy a Raspsberry Pi approach of using “the Cloud”. Google offers a one year free trial so I registered and tried a few examples on my Ubuntu laptop, amazing what one can do with just a few curl commands!

 

I wrote a sort of short tutorial. It is now obsolete but helps showing the way for further attempts.

I used an USB microphone because I assumed there was no LEGO microphones. But there is - the LEGOCam (MINDSTORMS RCX Vision) has an embedded mic, sound quality isn't great but might (big might) be used - that would make a 100% LEGO hardware solution.

By that time I had problems with initial authentication times - it took almost a minute before I can start using the Google services and it needed to be renewed after an hour.  EV3 CPU is slow but probably not the only reason here so one of these days I might try it again. Of course, using a Raspberry Pi and a BrickPi would give much better results.

Interesting. Thanks for posting.

I will take a closer look tomorrow

I stumbled upon RoboMaker on AWS today. Well, a friend sent it to me.

Edit: Created a separate topic for AWS RoboMaker and ROS
