Re: Robot Tipping issues

We did the sideways tipping test last night, our robot has to go to about 45 degrees leaned over before it will tip over.

Still need to do the front and rear tipping tests, unloaded and loaded. Although we kind of have a safety, since the tote stack falls over way too easily.

Re: Robot Tipping issues

We did two things to prevent tipping. We designed as much wait opposite to where we hold the totes/cans as possible. That wasn't enough, so we added weights (dumbbell plates) to the back. We also noticed that if the driver accelerated, or "decelerated" to quickly we could either tip, or lose our stack. So we implemented "ramping" code that limits the acceleration of the bot.

Re: Robot Tipping issues

We're about as tippy this year as we've ever been... it takes about 65 degrees before we'll tip over this year. We've had that number as high as 80 degrees in the past!

Re: Robot Tipping issues

We've designed the top deck of robot with the ability to slide back via a motorized lead screw. When we lift up 3+ totes above the top of our frame, our operator will slide the deck back, moving the C.O.G. with it. It will move forward when we're ready to score.
