Antaeus (also Antaios) (Ἀνταῖος) in Greek and Berber mythology was a half-giant, the son of Poseidon and Gaia.

He would challenge all passers-by to wrestling matches, kill them, and collect their skulls, so that he might one day build out of them a temple to his father Poseidon. He was indefatigably strong as long as he remained in contact with the ground (his mother earth), but once lifted into the air he became as weak as other men.

--------

This was my first ever project back in 2005ish when I was 19yrs old. Unfortunately, Antaeus was never fully completed due to life circumstances and ended up collecting dust in a storage unit for many, many years until recently, when I pulled him out of Hades and brought him forth into the light of day.

Originally designed to be a treaded bot, Antaeus sports a wireless nightvision webcam mounted on a servo, with a front-facing ultrasound sensor and IR rangefinding built-in to the Co-processor board. I used the Tamiya track set to construct his locomotion attached to two continuous rotation servos from Parallax.

His frame is constructed of sturdy 6mm Expanded PVC. He's quite the fatty--er---"heavy" lightweight. Antaeus weighs in I believe under 2lbs, fully loaded.

My original plan was to add on a GPS module (with an antennae wired above in the pole), along with an accelerometer and magnetic compass (Parallax version). As of the date of construction he features a BASIC Stamp 2e microcontroller mounted in a Lynxmotion Mini Bot Board II, connected to the Libby Board co-processor--an original creation by Harry W. Lewis of Blue Bell Designs (http://www.bluebelldesign.com). At the time (and still, in my opinion) a really nifty board made for BASIC Stamps and similar.

The Libby Board also features built-in IR rangefinding.

 

I was going to attach some (HUGE) RF serial modules that I found at a local electronics store to wirelessly control/program Antaeus, but along with the rest of the project i never got around to it. He will now be consumed by the Robot Gods and used for parts in other future projects to come.

Herein lies the final effigies of Antaeus, once formidable and mighty. May he rest in peace, amen.

Braiiiiiiinnnnnnnnsssssssssss. Basic Stamp 2e. I was going to switch it out for a BX-24 that I had purchased back in the day...

Yes, that is dirt/dust. He was a dirty, dirty robot :(.

 

Three cheers for Antaeus!

thank you for sharing antaeus!  i really like his style, and your write up also... it is very interesting :)

can you give any more info on the wireless web cam and the power system?  I am currently trying to find a small tiny little wireless camera system... and am not having much luck aside from the AI-ball for about $99 at the cheapest (but it is an IP wifi camera running on coin batteries)

I used something similar to this. Hacked the backing off and mounted it to a custom made servo bracket (just two pieces of wirewrapping style prototype board). It's powered by a 9v battery onboard with built-in switch on the leads for on/off.

The base station receiver uses a standard RCA jack (mine didn't have audio unlike the one listed above), which I then plugged into the computer using a Digital video recorder like this: http://www.amazon.com/EasyCAP-DC60-Creator-Capture-High-quality/dp/B002H3BSCM/ref=sr_1_2?s=pc&ie=UTF8&qid=1342316887&sr=1-2&keywords=rca+video+capture

You want to make sure to find one with IR LED's instead of the cheaper ones that use visible LED's for the nightvision :)

And viola! EZ wireless webcam for your bot.

 

As a side note, they also sell the tiny black pinhole cameras on ebay; they might use less power and smaller space, I think some are wireless too. And even cheaper.

Before you tear it apart, FPV that sucker! :D
