Elektro

Interacts with human beings

***Update 05/05/2012***

Elektro's brain under construction. The main power supply is in the moment a 7.2 V/4600 mAh NiMh battery. I have soldered Li-Po-battery connectors to the battery and main ON/OFF switch, so can change easily to a Li-Po-battery later.

A couple of diodes are used to drop the voltage to approx. 6 V for the servos. 3 low drop voltage regulators (LP 2954) power the main brain (in the moment an Arduino Mega 2560), sensors, amplifiers etc.

rmp3 is still not working with the Arduino Mega 2560, I have to figure out later.

This is my newest robot project: Elektro. I named him like this as a homage on Elektro; a robot built by the Westinghouse Electric Corporation in its Mansfield, Ohio facility between 1937 and 1938. As his predecessor, Elektro is made from aluminium sheet. I have used aluminium sheet with a thickness of 1 and 1.5 mm and some simple tools like tinsnips, a cordless Dremel and drill, a file, sanding paper and two squared timbers and clamps to bent the aluminium sheet.

Elektro's tasks are in the moment

  • Speech (MP3-player)
  • Speech recognition
  • Grasping simple objects
  • Playing with objects
  • Expressing feelings like joy and anger
  • Following people
  • Learning

So far his mechanical construction is done, shown in pictures below. Next step will be to build all the electronic sub-systems.

I hope you like it. I'll update this page as I make progress.

Ok, separated is ok, in case you want to exchange the µC later. 

Fair enough, bring him when he is ready :-) 

I dig the look of this little guy, kind of how I dig the look of a praying mantis!

I really like the metal work on it. What tools did you use in the creation of the aluminium parts?

Wow! How come I've missed it? It looks so much as my MiniEric robot! Nicely done! Can't wait for more action! I am waiting for my 3D printer to arrive to make new parts for mine so I can upgrade it, change a few broken servos and fix the servo jerks at startup. Then again, programming the mapping stuff, arrrgh!

Cheers!
