I've got my basic bot up and running (check sig for link to project).
I added an HC-SR04 to keep the bot from bumping into things. However, it has some limitations. Since it is mounted in the middle of the bot, it sometimes misses smaller objects (chair legs) that may not be directly in front of the robot, but will catch a wheel.
Can I use two (or more) HC-SR04s together? Or should I be looking at some other kind of sensor?
I noticed the DFRobot platform came with these three brackets that look like they would fit these nicely: http://www.dfrobot.com/index.php?route=product/product&path=36_55&product_id=114#.UeWTG40qaSJ
Should I add those to the ultrasonic to give it a larger sensing area?
I am going to play around with it of course. Just wanted to hear your thoughts/what you did.
