One of the problems has been how to sufficiently agitate balls in the hopper to keep them from jamming en route to the shooter.  Team members have consulted with mentors and looked at various examples of mixers and agitators in evaluating what might work in their case.  They’ve considered everything from static mixer designs to paint mixer concepts, looked at how

A team member employing Google Sketch-up was able to model,  fairly accurately,  the behavior of balls  moving through hoppers of various configurations and using different types of agitators, to help team members better visualize the physics at play.

Between puzzling over design problems and cheesecake breaks, team members also finished work on their new banner,  a breath-taking work of duct tape art!  Hopefully our mid-week meeting will bring some equally dazzling resolution on the robot build.
