Quadruped > awaiting rebuild :)

Let's Make Robots Robots
1

My first attempt to build and run a quadruped. Parts of laser cut acrylic. Powered with an arduino uno and sensorshield. Total of 12 micro- servo's, partially metal geared. It proved very difficult to align the servo's right. It walked, it turned. But was abandoned after I blew up most of the servo's by feeding them 7,4 Volts instead of 5 :P

Anyway, it's pretty much a copy of this one: https://www.robotshop.com/letsmakerobots/node/34412

I had to use 3mm acrylic, because the lasercut firm had no 4 mm available.

Initially run it on a heavy 7,4 V lipo (5000mAh) through a wire because I didnt have a light enough lipo at hand. The voltage regulator ran very hot in the first place.

And yes, I nearly have all the parts at hand to build it again, and will in the near future.

If there are any specific questions, I'll try to answer them, of course.

Thanks for posting - can you

Thanks for posting - can you please provide a little more information on your projects? The pages appears awfully white :slight_smile: Thanks.

It’s about the build process—not the robot!

What were your design considerations, huh?  So many questions yet so little answers…

Primairily I wanted to build

Primairily I wanted to build a multi legged bot, but keep the costs down.

I’m a newbie, so no experience in designing and designing software, no high tech tools to work with, etc etc :slight_smile:

Also no profound knowledge of C, but have done a lot with msx-basic in the old days, so I’m learning on the go, so to speak.
