I have been looking at the hercules 4WD platform and was wondering if there was a way to replace the encoders with something more accurate. I’m working on a school project for algorithms and want to be able to track the position of the bot more precisely. One of the concerns I had with just replacing them was limited space in the bot. Any feedback or suggestions would be very helpful.
Unfortunately not - at least nothing from the manufacturer. You would need to see if an encoder from another manufacturer might fit the rear physically, as well as the shaft. You might try adding an IMU for improved positioning.
