Weird legged PCB Robot


This is one of my weird robots build with Veroboards.
It has two legs that they push the entire robot, which is standing on two free running wheeles.
Characteristics
  • CPU: Basic Stamp 2. Board of Education
  • Motion: Two legs with 3 degrees of freedom each (Each leg looks like a PUMA manipulator, without the end effector tool). Two free running wheels are used at the frontend (no extra motors). The legs are pushing the robot like a cart.
  • Motors: Six small servomotors (1.5 Kg). Three motors on each leg.
  • Sensors:
    • Eyes: Two infrared transceivers at the front, for object avoidance.
    • Ears: Two microphones. Capability to detect sound direction.

Soccer and Sumo Robot...


OK, this is a new design I am working on. It's a small robot with a kicking mechanism, a grip and a lot of other cool stuff (e.g. BlueTooth and the ability to control it with an Android app, the ability to charge it to a charging base and much more). This is the prototype and I built it for the tests. Curently I am working on the new improved PCB's
It is Arduino based
I have also some thoughts of implementing a txtzyme style language or a visual style programming using Blockly (or maybe I will combine tose two techniques)

Pluto

This is the best photo of the planet Pluto we have untill now. At least until NASA's new horizon mission arrives to Pluto in July 2015.
Pluto was the most distant planet in our solar system, until astronomers discoverd new Kuiper belt objects. Officially Pluto lost the "title" of a planet and now is considered as a dwarf planet (and generally is a Kuiper belt object).


We practically know nothing about Pluto. We know it has one big moon (for its size) which is called Charon (it's the small spot you see on the top right of the photo) and four smaller ones (Nix, Hydra,Kerberos and Styx). This particular photo was taken by the space telescope Hubble at 21 February of 1994, when the distance of the planet from Earth was 4,4 billion km. The photo is very clear in comparison to those surface telescopes and we can see the two objects perfectly separated
