conVERSE biped

Autonomous roaming using bipedal movement and 6-servos

This is a biped robot named conVERSE. This is a modified BRAT kit from Lynxmotion. A truly fun build, by the way. The Basic Atom Pro mounted onto a Bot Board is perfect for this sort of application and the robotic platform affords awesome stability and durability. The higher the servo torque, the better the movement.  the servos used for this bot are Hitec 422s.  The vids show conVERSE with a slow steady gait. I made some modifications to this bot, including the custom tailoring of a leisure suit for those special times when conVERSE steps out on the town in botSTYLE. He roams autonomously using a Sharp I.R. sensor and employs a small remote camera so the creator may view the world through conVERSE's eyes. Or should I say 'eye'.  Anyway, some of the vids may not be suitable for younger viewers since I included his early walking clips. You will note conVERSE had no clothes back then. There's plenty of code out there and the BRAT community has grown dramatically so there's lots of secondary research and data to rely upon when playing with this little fella.

Finally, his name came from one of my son's beat up sneakers.  I found one of the kid's Converse id tags lying on the floor and found it mounted nicely just under the I.R. sensor.  The result...this biped's name forever more will be conVERSE.

This is pretty cool! I'm planyng to build something like this over the Summer break... I think I'll be using an arduino as the brains of the robot and "6" 6v. servos. I'm only 13.... "Hope it turns out fine...  :( "

For your first biped, consider a 4 servo walker.  It's easier to program and less expensive to build.  The Arduino is a good choice I think.  Do a web search for 4 servo biped robots and see what you come up with.  Check YouTube out for a vid.  I think you can find detail on such a build on the Lynxmotion website.  Research and planning is half the fun when building a biped or any other robot platform, for that matter.  Good luck.  Thanks for the comment.


Some diagrams I drew...

This is great schematic of your vision for a biped.  Consider the code compexity as it relates to leg geometry.  Also consider the servo torque that will be necessary to insure stability of movement.  The more servos, the more degrees of freedom...the more complex the code and higher the cost.  That being said...make no small plans.  Jump in with both feet if you wish. That's the beauty of robotics.  It's spectacular when you finally get your critter to move as intended.  I would suggest you start small during your prototyping phase.  Begin with 4 servos on your way to six.  Perhaps you'll want to design one leg at a time.  Gain an understanding of your creation. Seek information throug research as you go.  Learn from others on your way to your own innovation.   I have a feeling you'll do just fine. 

Thank you for all your help! Can't wait to get started!

Haha, i like the idea with the clothes...can not remember another dressed robot here :-D

Custom duds for robots...what a concept.  Thanks for your comment.

Yeah cool, we could run a competition who has the best dressed bot on LMR :-)

Latest video reminds me of Wallace and Grommit in The Wrong Trousers.
