I know I can use a worm gear to solve this problem but wanted to see if there were any other solutions before redesigning the attachment. Without knowing the full details of your design, it would be a bit difficult to recommend anything very specific. Is your motion of the motor limited in direction? If so, a ratchet system can be extremely effective, even ...

According to the official documentation you could use hold() which Stops the motor and actively holds it at its current angle. Note: My assumption here is that you are referring to this as "large motor". If you are using a PF Large Motor: then this advice is useless, as those can't be controlled with such precision due to the lack of an ...

The ultrasonic sensor is useful for navigation. This robot design has a nice skirt and positioning the ultrasonic sensor should not interfere with that skirt. Also the ultrasonic sensor is excellent at detecting right angles like the floor meeting a wall. So, I'd recommend positioning the sensor on either a side (for following along a wall) or the back (...

You'll be able to control the 9V motor as an unregulated motor with the similar named motor block, you'll be able to set the speed approximately, but any accurate RPM control is out of the question as there is no feedback pulse signal from the motor to the EV3 telling it how fast it is going. Also there are some programming quirks with this cable and an EV3, ...

MIT App Inventor is a popular way to make simple Android apps that can communicate with an EV3. It has special blocks just for EV3.

I don't think an .rbf file is ever generated, the microPython engine installed on the flash disk interprets and executes the .py file directly. .rbf files were executable files generated by the EV3 software, i.e. either the graphic programming language in the old version (with blocks you needed to draw) or the scratch based new software. I think you should ...
