Automation Robots Set — High Bay Storage Rack Fixes

The high bay storage rack from the Robo TX Automation Robots set is an amazing piece of engineering.

However, it requires a precision of less than 1 mm, close to fischertechnik system limits. Some axis are too tight, some parts require manual adjustment. 

Here are the modifications I brought to the initial design in order to improve the reliability of the model.

Please refer to the manual for the parts list corresponding to the mentioned steps.

Step 4

The X-axis is too tight.
  • Omit 37679 close to 37858 + 35112
37679
37858 + 35112
  • Place two 37679 close to 32064 and 35031 + 31021 + 31058
37679
32064
35031 + 31021 + 31058

Step 8

The Y-axis is too tight.

  • Omit 38246

Step 20

The Y-axis motor collides with the 32870.

  • Keep some space on the 32870
32870
Cables mess with the linear translator.

  • Place the 2x 38216 on a 35049
38216
35049
  • Place the combined result on the other face

Step 22

The BOM doesn't supply enough 31061. 31330 is recommended for better stability.

  • Replace 2x 31061 by 2x 31330
31061
31330
The Z-axis is too tight.

  • Remove the small pins on the 36334
36334
  • Place the special 36334 on the end of the Z axis
36334

Step 23

The position of the head needs to be manually adjusted to be just in front of the input/output area and the storage areas.

  • Turn the vertical 32879 by 90°
36879
  • Use a 31982 instead of 31060 for adjustment on the X axis
31982
36879
  • Adjust manually the head on the X axis
