Let's Make Robots!


July 7, 2013 I started to build the first prototype of Cosma. Cosma is basically a robot astronaut. The primary goal of this robot project is to send a small … Read more

US English editor needed

For my current project Cosma I need to develope phrases in proper US English, let's say in a range from 1 to 5 (1= acceptable condition, 5 = unbearable):

1. Pain triggered by pressure on skin or muscles

2. Temperature (coldness)

3. Vertical positive acceleration

4. Vertical negative acceleration

5. Pitch, Roll, Yaw

6. Noise

7. Brightness

Here is what I came up:

COSMA's brain

Attached you find the Rev. 0 schematic of COSMA's brain (Eagle). This board connects directly to a FTDI  board. As I need MOSI, MISO and SCK also for the micro SD card, I added solder jumpers, so those pins are not connected to the SD card/voltage level shifter while burning the bootloader on the chip.

The board mainly contains:

- ATMEGA2560

COSMA - Update 2

For the first protoype of COSMA I decided to build stackable proto shields for the Arduino Mega. Later I will layout a single PCB, including all.

Proto shield one

Proto shield two

COSMA - Update 1

In the meantime I named the robot astronaut Cosma, a maiden name, ancient Greek for Cosmos. Below you'll find a more specific design study. I think I will 3-D print the main body and the head. I've furthermore tested a FSR (force sensing resistor) as a kind of pain receptor and the ArduEye.

Robots in space.. and no Windows!

Ha, I just read this article, and thought I'd share:


Apart from the fun no-more-windows-part, I think the robot part is quite interesting - some new challenges there, zero gravity.. Hmm .. hard to test at home :)


10 pts to whoever gets the title reference.

I was perusing all the amateur DIY near-space balloon flights that have been gaining popularity lately, and a thought hit me.

Would it be possible to have a two stage flight; first stage would be the balloon and payload reaching a certain altitude. The second stage, when this specific altitude is reached, a ROCKET is fired from within the payload, taking it further into space (hopefully reaching escape velocity.

Emits bright light and loud noises =D
Around the end of February every year there's a 'Chinese Lantern Festival' that happens in my city. Lots of junk to buy, cool lanterns, interesting food, and most … Read more
