  2. My latest demo robot for a Automation club I belong too, thought people here might get some use out of it too - since I used a Launchpad MSP432 board :-) http://www.instructables.com/id/Obstacle-Avoidance-Robot-Using-TI-Launchpad-MSP432/
  3. Researchers from University of Lincoln published a paper on their 25 quid design, 4 cm mini robots for swarm applications. It looks like comprised of one 168 and one 644 in the design. Video Paper PDF http://cdn.intechopen.com/pdfs-wm/47293.pdf Looks lovely to see them gather around the light source.
  4. I've finally gotten around to documenting the Cardboard Hovercraft build to such a detail that anyone else can build one. Since it has a bluetooth/wireless control component, I'll be documenting it at hackaday.io
  5. Recently finished my first msp430 based robot, a Basic Light seeker! This was a project to get me to learn more about the MSP430 microcontroller. In this project specifically, using multiple ADC inputs and PWMs ( 2 PWMs was a little tricky on the MSP430G2452 but eventually got it ). The robot turns according to the difference between the light values on the left and right, using two Photoresistors/LDRs. The robot is powered my a set of 4 to 5 NiMH 1.2-1.4V batteries which directly power the l293d Motor Driver IC and DC motors, and is also fed into a LP2950-33 3.3V LDO to provide regulated power to the MSP430G2452 IC and Photoresistors/LDRs. Most of my robot designs use a separate power supply for control and motors for stability, but this one has been fine so far and has an abundance of filtering caps. For a better description look at my blog post here: http://emdinventor-blog.tk/light-seeker-robot-with-msp430/ and for the code look at my github repository for the robot's code here: https://github.com/emdarcher/msp430_tank_robot Some pictures of the robot: Fritzing diagram ( missing 0.1uF filtering cap across Vcc and GND on the mcu ):
  6. Just came across this Kickstarter that features the MSP430G2553 LaunchPad and Energia: PicassoBot, the Portrait Sketching Robot Kit. https://www.kickstarter.com/projects/educatedrobot/picassobot-the-portrait-sketching-robot-kit
  7. OK, I'm pretty new to the BBB and my background is in programming not electronics. I would really like to setup the BBB as a robotic arm controller. The arm I'm looking at is the Lynxmotion AL5D 4 Degrees of Freedom Robotic Arm. http://www.robotshop.com/en/lynxmotion-al5d-robot-arm-combo-kit-4-dof.html#Multimedia Is the BBB capable of controlling this 4-axis robot? I would assume I need a cape to do this but can't determine if an existing one would work. Any guidance would be appreciated.
  8. Please see the attached file. Thanks, Dan Harres MSP430 Fast and Fun Robot Car Announcement.ppt
  9. Just found out that Target has a really cool christmas giftcard this year. Between Target and Bestbuy, you can always get nice free stuff. The "Draw and Go" Giftcard at Target is a Line following robot, shaped like a bone car. It has four LR44 batteries (two for 3v to the driver, two for 3v to the motors), two infrared transmit leds and receive leds, a few j3y smd transistors, two metal weights a unlabled 8 pin soic chip (Comparator? MCU?) and two independently geared and controlled motors in a single package. This thing is perfect as a little robot car platform. Or get two or four and bolt them together to make a bigger car. (To get it open, you need to make a hole on the three bottom pegs that cover the screws as you can see in the picture. I stabbed them with a small jewelers screwdriver). You can easily replace the controller with a msp430. And the kicker, it's free. Well, you need to put at least five dollars on the gift card, but you can use it right away. I had to buy some groceries anyway. No limits. They should have them by the registers, or the greeting card aisle. If anything you can always ask them were they are. These are christmas related, so once they run out, they won't restock them. In the last few years, Target has had glowing led cards (wii, and generally very often christmas ones), led and sound (xbox), usb flash drives in credit card shape (speed racer), digital camera and mp3 players (50 dollar gift card required), RC cars, legos, all sorts. Bestbuy has had some of the same, including usb color changing leds, and usb hubs, and you only had to put 1 cent on them. None this year though.
