Thread: Mantis - Two Tonne Turbo Diesel Hexapod Walking Machine

  1. Mantis - Two Tonne Turbo Diesel Hexapod Walking Machine

    So it may have taken me much longer than I anticipated.. 3.5 years, but here it is.. finally!

    More information and images can be found here:

    www.mantisrobot.com

    *EDIT* People who are interested in the build process and test footage etc, there is plenty of this on the Facebook page above, alos I have just opened up the blog that I kept during the design and build, which is really just a build diary:

    If you like what I've done with this project, please help promote it the usual way.. Like/Tweet/Share/Forward etc

    Well damn. That is some niiice work. Congrats to your team on a job well done. Will there be more footage of it on uneven terrain?

    I'm in awe!

    I looked at mantisrobot.com but apparently it's a parked domain?

    You need the www. for whatever reason.

    Yeah I'll try fix the mantisrobot.com, the www. does work though.

    Small team on this one, which is why it took me so long Just me and one other mechanical engineer worked on the desing and initial build for a year, with lots of the big fabrication outsourced. Then I had another guy help out with the Operator Interface software on the WinCE touch panel you see during power up, the rest has been on my own.

    There is already a bunch of footage and images on the facebook page.

    Currently the only sensors are in the feet, so it is walking blind, hence needing an operator to guide it. I have plans to add non-contact sensors to the legs to detect obstacles, but need to get some feedback on this first to see if I can get funding to take things further.

    More and more giant hexapods on the scene... I like it!

    How hard is it to operate at this stage?

    Easy to operate, power up and power down need a little concentration, but once you know what your doing...

    Could you share the trade-off why you chose hydraulics instead of generator + electric motors?

    When is the last time you saw a purely electrically actuated (de-)construction vehicle other than a crane? Electric motors work really well in enclosed industrial facilities, but not so much outdoors (lots moving parts that are sensitive to humidity and debris that have to be well sealed against intrusion). Hydraulics just tend to be more resilient (built in damping), and cheaper and easier to build and maintain in that sort of environment. Also...

    I was thinking the Lego Power Builder ride, but you're right: that's indoors!

    I drive an electric car, and I have a friend who's designed a hybrid diesel-electric drivetrain that uses a diesel turbine to generate electricity to drive delivery trucks, so clearly the electric motor thing *can* be made to work in a rugged environment.
