Refurbishing Robot

Posted by Erin, the RobotGrrl on Wednesday, July 21st, 2010

The missing parts to the TECHNOROBOT kit that I got at the explOratorium during the Stanford EPGY AI Program in 2008 have been found! This robot has been transformed many times, the first as an idea/prototype for an emotional line following robot, then a snowplow, and now it will be an XBee messenger robot!

Refurbishing it was OK, it only took 4 hours. The only thing that was drastically broken was the drive axel. To fix it, I used some Lego axels.

The robot now uses an Arduino, and is powered off of USB. The motor is driven with the Adafruit Motor Shield (I plan to add more motors to the robot someday). The motor is powered from an Adafruit mintyboost.

I broadcasted the refurbishment to the Fat Man and Circuit Girl stream, AND took a photo every 5 seconds! You can see the HD timelapse on Vimeo!

The next steps for this robot is rather short:

• Make a battery pack for the Arduino
• Attach XBee
• Mount an ultrasonic sensor, program a simple behaviour
• Transmit messages, listen to messages

Can’t wait to blog more about it!

MANOI-in-a-box

Posted by Erin, the RobotGrrl on Wednesday, March 24th, 2010

Team 229 is heading to a FIRST competition this week- and since I don’t have three tests on one day I can actually go to this one! WOOHOO!

The location of this competition is one of the most awesome ones… APPARENTLY iRobot scouts people there. Meaning, they’re hunting for smart brains to hire during the summer. :XD: Even though I don’t roll with military style robots (they aren’t supposed to be sociable), that’s pretty cool, to be honest.

I figured that it would be awesome to carry MANOI around and just having it wave its arms, with a Team 229 flag (see picture above). I think some High Schoolers may enjoy that.

Transporting MANOI for the past few years has been a hassle… so we finally found a good box with styrofoam stuff in it! The styrofoam is actually really nicely engineered, because it comes cut into rectangles, which means that you can easily customize it. This is how MANOI fits in its new box:

There is room for MANOI’s basic needs in there- the batteries and charger, ping pong balls, USB cables… etc.

The outside needs more stickers, but I have the classic FRAGILE one, and a “Made with LabVIEW” sticker — even though it’s not even relatively made with LV. Hahahaha! I’m thinking of printing out a picture of an Arduino and taping it on there.

The other day, a member of CUARC with a dremel cut a hole in this metal box for me… Can you guess what is on the inside?

IT’S A MINTYBOOST! YAY!

This will provide MANOI’s microcontroller with the power that it needs while cheering on Team 229

I haven’t programmed the motions yet for MANOI, but I can do that in the hotel tonight. I’m thinking that the legs will be stationary, and just have the arms move around. Also thinking of using the Wii nunchuck to control which sensors are being read or something. I will indeed post the code when I make it! =)
