EV3 Simple Remote

A Precision Tool for LEGO Mindstorms EV3 Motor Control

The EV3 Simple Remote is a focused, no-frills utility for anyone who builds with LEGO Mindstorms EV3 and wants direct, tactile control over their robotic creations. This is not a game or a simulation—it is a functional remote control application designed to interface with the physical EV3 brick via Bluetooth. Developed by Ferdinand Stueckler, the app strips away unnecessary complexity to deliver a straightforward motor management experience.

At its core, the app provides independent control over motors connected to ports A, B, C, and D. The interface is built around a simple button layout that allows you to select and drive specific motor combinations—using dedicated keys like AB, BC, and CD for paired control. A notable feature is the reverse function, which instantly inverts the direction of all connected motors with a single tap. This is particularly useful when you need to change the movement direction of a robot or mechanism without reprogramming the EV3 brick itself.

The standout addition is the Sense Mode, which introduces a more nuanced interaction. In this mode, the app responds to press-and-release actions, allowing for precise incremental movements. A dedicated red button enables fine rotation control, giving you the ability to make micro-adjustments to motor position. This is a significant upgrade over basic on/off controls, as it allows for careful positioning of arms, grippers, or wheels during testing or operation.

The app is remarkably lightweight and compatible with Android devices running as far back as version 2.1. It requires no additional software on the EV3 brick—just a standard Bluetooth pairing. The developer has tested it on Nexus 4 and Nexus 7 devices, ensuring reliable performance on older hardware. There is no bloatware, no unnecessary animations, and no advertisements within the app, making it a clean tool for focused work.

• Direct motor control: Manage ports A, B, C, and D with dedicated button combinations like AB, BC, and CD for quick selection.
• Reverse function: Instantly invert all motor directions with a single tap for rapid directional changes.
• Sense Mode precision: Use press-and-release and a red button for fine rotation control, enabling accurate positioning.
