Love it! That's just excellent, love the way it moves!

Could you give a bit of a description on how it works? e.g. what sensors do you use? How mucah of it's motion is autonomous?

Thanks richiereynolds...

It is fully autonomous !... it makes use of Infrared sensor to sense any blockage ahead (25 cm), if it does, it stops and identifies if the obstruction:

1) has a gap underneath (Task 1)
2) is a slope (Task 2)
3) is a sudden height (Task 3)

it does that using IR sensor which can orientate up and down, it measures distances to identify if it is Task 1, 2 or 3.

And, the whole time it is walking, not only it checks for blockage ahead, but it keeps on checking if the light-sensors (that are located on its feet) senses a 'larger' distance (black + light-ON) when the foot is down ! [it checks for light-sensor value only when each time the foot is down] - if it senses larger distance, that means the surface is Irregular ! (Task 4) - it steps backwards in order to Transform.

Thanks  :)

One of the best things I have seen... Congrats mate :-D

BTW... would you mind sharing the music (the name ;-))

Hey, awesome robot! Great ingenuity and problem solving!

Love the last scene in the video too.  :D

Congratulations!
I think the chauffeur did it.

Thanks man!!!

BTW... The arms servos seem to oscillate a lot, have you considered including slew rate?
Just to do away with inertia!!!  ;)

Thats amazing. Apparently that Axon microcontroller can do alot. I'm just wandering how long it took to program it?

I pulled all my hair out answering your debugging questions, so its good you got a nice robot working there :D :P

You should definitely enter this into my contest. Just have youtube add a pop-up bubble to point out the Axon to qualify:

hi hassan..,
ur project is quite superb, n its a splendid job. its a great work.
is tat a remote operated or fully auotmated? what sensors u have used? how much it costed totally for the project?

That's nice! very clever! I just have one question though: why does it ever use the 4 legged walking mode? It looks really slow and clumsy, not the most effective way of getting around on a shiny floor!

Fantastic work though! :)

Thanks Chris,

It needs to be in 4-legged position as its 'default configuration', so that its IR sensor is in much higher position and can sense what obstruction is ahead of it, so, ANY other configuration would have prevented it from identifying the task.

By the way, its walking gait was suppose to be like animals'.. but i was forced to "reduce 1 servo" from each leg due to its weight and some electrical (power) problems - I was running out of time - that was the only solution I got !

Anyway, "building a robot" was not even a part of my project, I wasn't assessed on that either. I built it to prove my 'research' (design), but mainly for fun !... so pls dont expect it to be 'perfect'. :)

Thanks

this robot is awsome. what did you think of the microcontroler?
really good movement. does it avoid objects like walls?
