SCORBOT Ru4 Encoder Wheel

thingiverse

This encoder wheel replaces a Pittman motor on an SCORBOT RU4 robot. The openings are slightly deeper than those on the actual machine, but it fits perfectly onto the shaft with a press fit. The original encoder wheel is secured to the shaft using a 000 set screw. To ensure accurate readings from the encoder, it needs to be printed in black; otherwise, the slots may not be distinguishable, leading to poor performance. Unfortunately, the encoders used on the robot are no longer available for purchase, making this custom part a vital solution for educators still utilizing these robots. The picture I uploaded shows the completed encoder wheel built using an M3D printer with carbon fiber filament. While it's not aesthetically pleasing, some minor adjustments with a file and razor blade were enough to make it functional. We printed additional units on better printers with superior results, but our workplace lacks black filament, so they would require painting before use.
