(...) So, what exactly is a gravity tube? Maybe you mean something like: Empty Full Half-full | | |o| | | | | |o| | | | | |o| |o| | |___ |o|___ |o|___ |_____ |o____ |o____ Hence, when a ball comes in (from bottom right of the tube), it pushes a ball (...)

Hi Rob, (...) I tried a similar mechanism (a large inclined plane with a width reduction in the end), the problem is that LEGO balls are somewhat rough, and they tend to form a locked arch above width shrinking. I even tried to add a stirring (...) (20 years ago, 8-Dec-04, to lugnet.technic, lugnet.robotics)

(...) Looks fun ;o) One of my goals when building Bob's clock was to get my feet wet in ball moving... One foreseeable issue: if an upstream unit has more throughput than a downstream one, we shall get ball overflows! Philo (20 years ago, 9-Dec-04, to lugnet.technic, lugnet.robotics)

(...) There will be a minimum throuhgput to solve that. Right now, we're testing with 1 ball/second. So, the very first module will be regulated to run somewhere just below that speed. As long as everyone else can meet the minimum, there will be no (...) (20 years ago, 9-Dec-04, to lugnet.technic, lugnet.robotics)
