MindWave "cracked" .. or mostly so..

GroG's picture

So Ale, this is the contents of the file you sent me...  I was looking at the MindWave parsing stuff.  They have a "Dummy" data generator for testing - which is very nice.  Looking at that I thought I could figure out what to expect from the MindWave device. 

PIR - we will make it WORKY!

Alright - finally got my PIR connected - big delay was finding correct jumpers for it.

This is an Arduino Uno connected on digital pin 7 with just an Arduino service

Works as I expect it would - 3 second delay after a signal .. goes back to low if not triggered again..

If you don't get this far, we need to find out why...

Well this is exciting Gareth is Clang Clang Clang at adding another micro-controller to the MRL BORG !

Mysterious Moving Issue Solved (I think)

Gael described a problematic issue where omoplates and other parts failed to reset themselves after a "rest" command.  It was difficult because it did not seem consistent.  Problems which always fail 100% are usually easy to solve. This one wasn't.  But I think I've got it....


Torso - reloaded

i01 = Runtime.createAndStart("i01","InMoov")
torso = i01.startTorso("COM16")
torso.topStom.setMinMax(60, 120);
torso.midStom.setMinMax(0, 180);
torso.lowStom.setMinMax(0, 180);
i01.moveTorso(50, 90, 73)

Torso script work-around

Torso work around in script .. until I have time to get back to it ...

Challenge for Alessandruino

This is a promotional video .. well made .. but not "for real"...
Will happen sometime.. I think weight and power limitations are the biggest hurdles (not to mention local legal restrictions) .. regardless would be fun ;)

Thanks Adolph for this great find !



I have thought many times in the past, that most of the walking bots are way too stiff.. Besides boston dynamics I saw a cockroach video where metal leaf springs were incorporated - what a big difference in gate !
