A dream. This must be...
It look incredible Matt. Very well done. I'm really looking forward to see it doing some body movements and walking.

Fantastic!

Where did you learn enough about hydraulics to put this together?

Thanks for sharing.

Well I had done a small amount of hydraulics control back in 1997, but nothing as complex as this, nor indeed had I ever had to make a diesel powered hydraulic power pack, so I learned during this project. Naturally knowing what I know now there are changes that I would like to make..

Well here is the official Promo video for the Mantis:




If you're looking for technical stuff, there is a facebook page here: http://www.facebook.com/mantisrobot with lots of images and video taking during the build, I will slowly upload these videos to YouTube.

Also more tech. data on the website: http://www.mantisrobot.com

And if tech. stuff is really your thing, I have just opened up my blog page: http://mantisrobot.blogspot.com This was really a build diary for the project with many pictures and text describing various issues and achievements throughout the three year design/build.

If you like what I've done with this project, please help support it by liking the facebook page and share with your friends :)

I'm absolutely speechless, this is over-the-top impressive. Looking forward to hear more about the software driving this machine, and which safety measures, that have been built in.

I've been asked for more technical information, particularly by Rick Lehrbaum for this Linuxgizmos article:

So here is the Mantis Hexapod control system architecture / overview:

Image

Also this may be of interest, this is part of the H&S document for Bestival 2012, showing the working envelope and operational guide lines:

Image

When the machine is powered up, the following applies:

RED: (No Go Area)
When the machine is powered up, under no circumstances should any personnel enter the Red area. Only when the machine is powered off or in a low power state can trained personnel enter this area.

ORANGE: (Leg Operational Area)
During normal walking operation the legs should stay within the orange area, but can be over-ridden under manual control by the operator to reach within the yellow area.

YELLOW: (Leg Reach Area)
The yellow area is the personnel clearance distance during operation. This represents a 3000mm radius from the leg coxa/hip joint that places personnel outside the maximum reach of a leg.

When the machine is powered off, all areas are safe, however, if the machine is supported above the ground by its own legs and without any prop stands, NO personnel should go underneath the body!

Here is another video shot in 2012 during field tests. Includes footage at the end of how I transport the Mantis.
