View Full Version : Robot With Arm

11-17-2008, 12:24 AM
Just got done the other day testing out my new robot. It is made mostly from wood and cardboard to cover the plywood. It is a good design for people like me who don't have the big tools like mills etc. It stand a little over 5 ft. and can lift up to a 2 lb object from the floor to 45 inches in the air. Here is a link of it picking up a vase http://www.youtube.com/v/4U5sAa6NJlI and a ball http://www.youtube.com/v/6Jzo814u96E For now I control it by decoding the signal from a "VEX" transmitter (they are so cheap from ebay). I built 1/2 H bridges (is that a S bridge ?) to run the DC motors. The robot is light enough to lift and carry with one hand.

nice robot. I especially like your creative use of materials, and how strong it seams to be. Is your robot automatable?

I always seam to get in trouble for asking, but would this qualify as a junkbot? (http://forums.trossenrobotics.com/showthread.php?t=2472)

In anycase, cool robot.

Thanks 4mem8 & darkback2. Is it a junkbot? It more of a "kitchen sink" bot. The cardboard is from cereal boxes. The pads on the fingers are from sponges. The small fingers are made from paint stirrer (strong wood for it thickness). The axles from nails, etc & etc.

It's not autonomous yet but it was built with that in mind.

By junkbot I mean did it cost you less than $100 to build, and is it eligable for a robogames 2009 event. The junkbot challange is an informal contest of sorts. We build robots on the cheap, and then people vote on which one is the best. The prize this round is $50 streight up cash! I'll make a link to your post on the junkbot challenge thread...if it was more than $100 then I'll take it off.

Hi darkback2: Yes, it cost more than $100 to build.
