fischertechnik Kits
Fischer makes a lot of fun kit projects. The projects shown here are built from the instructions provided with no modifications, other than the usual fine tuning. More projects are on the way...
I really like the pneumatic kits so let's start there.
This is the sorting machine, built from the Pneumatic Robots kit (part 34948). A photoresistor measures the amount of light reflected from each disk to determine whether it is black or white. Then the "conveyor" advances, and the disk is kicked into the left or right bin by pneumatic actuators. On the left behind the project is the air pump.
This is the machining station with defective part rejection, built from the PneuVac kit (part 500883). The idea is that white disks pass on and get "stamped", but the red and blue ones end up in the reject bin. Unfortunately it wasn't tuned quite right, and it mistakenly stamps one of the red disks. After all the disks in the magazine have been processed, the machine idles in a wait state. At the very end of the video a blue disk is placed back in the magazine, it is detected and the machine starts up again.
