HylianSavior 37 Posted June 30, 2014 Share Posted June 30, 2014 http://youtu.be/I0JuGvbfIIE http://boosterbot.in https://github.com/Hylian/BoosterBot http://hackaday.io/project/1845-BoosterBot Here's a BoosterPack that @@szhao, jwp071, and I are working on. It's a BoosterPack that turns a 40-pin Launchpad into a fully functional robot. It has two Micro Metal Gearmotors from Pololu driven by a DRV8833 motor driver IC and has five QRE1113 reflectance sensors from Fairchild for line tracking. It also has breakouts for a Sharp IR distance sensor and a servo. For power, a 3xAAA battery holder fits between the LP headers, which powers the 3.3V and 5V pins, as well as 9V for the motors. No pictures yet, as I'm in the middle of routing the board. I'll post updates as they come. Edit 6/30: A picture of the board in progress: https://dl.dropboxusercontent.com/u/538662/robot-boosterpack.png You can see the motor mounts at the far end. Edit 7/1: Quick update: https://dl.dropboxus...oosterpack2.png The five sensors up at the front are reflectance sensors on the bottom of the board for line tracking and maze solving. The middle three are for PID line following, and the two at the edges are for recognizing splits in the track bluehash and Automate 2 Quote Link to post Share on other sites

This will make a good starter pack. Anyway we could help in terms of parts or boards? Quote Link to post Share on other sites

I'm concerned that some of the tall tantalum caps and inductors will scrape the ground, as they're on the bottom of the board. I'll have to flip them to the top if there isn't enough margin.

zlalanne 37 Posted July 3, 2014 Share Posted July 3, 2014 The BoosterPack looks cool! I enjoy seeing robotics projects simply because they are very tangible and make for a great demo. What sort of chassis are you using to mount the board/motors to? I recently developed a BoosterPack that goes with SparkFun Magician Chassis that has been working great for me. Here is the 43oh thread about the BoosterPack http://forum.43oh.com/topic/5558-redbot-boosterpack/ Quote Link to post Share on other sites

Here is the 43oh thread about the BoosterPack http://forum.43oh.com/topic/5558-redbot-boosterpack/ The idea is that everything mounts straight onto the BoosterPack so the board itself is the chassis. You can see that the motors are mounted straight onto the BoosterPack in the back of the image. This is for the Intern Design Contest so keep an eye out for it! Your BoosterPack looks really nice as well. I've used the Magician Chassis before and it's great. Quote Link to post Share on other sites

This is for the Intern Design Contest so keep an eye out for it! Neat idea, mounting to the BoosterPack makes it simpler. I'm guessing M1/M2 is where you plug in the motors? What are you using for the front to keep it balanced? Some sort of caster? Quote Link to post Share on other sites

HylianSavior 37 Posted July 7, 2014 Author Share Posted July 7, 2014 Board routing is pretty much complete! Still need to add in ground planes and do a DRC. Also, the hole for the ball caster in the middle is made of three overlapping drill hits at the moment, which isn't supported by the fab. I'll have to change it to a cutout, which I'm not feeling too great about. Quote Link to post Share on other sites
szhao 17 Posted July 7, 2014 Share Posted July 7, 2014 I have also created a prototype of this boosterpack using the LaunchPad box as the chassis. Check it out here. Quote Link to post Share on other sites
HylianSavior 37 Posted July 8, 2014 Author Share Posted July 8, 2014 Design is finished and sent to the fab! It's now been christened as "BoosterBot". GeekDoc, bluehash, adrianF and 1 other 4 Quote Link to post Share on other sites

HylianSavior 37 Posted July 25, 2014 Author Share Posted July 25, 2014 Board all soldered up and working! Hopefully we'll have some demo videos out soon. bluehash, zeke, oPossum and 2 others 5 Quote Link to post Share on other sites
jwp071 0 Posted July 25, 2014 Share Posted July 25, 2014 Looks great! Nice job with the soldering, Edward! Quote Link to post Share on other sites
adrianF 43 Posted July 31, 2014 Share Posted July 31, 2014 Super cool! Can't wait to see someone stack the CC110L SubGHz RF BoosterPack on top of it to enable it to be wireless-ly controlled! Nice work guys! Quote Link to post Share on other sites
