What's New in RoboSimL

1.1

September 18, 2026

A redesigned look, and a field that plays fairer. MENUS AND HOME SCREEN • The home screen now puts your robot on a slow turntable, with the menu docked beside it. • A row of chips under each robot's name shows what it's built from at a glance — drive and lift wattage, and its intake or claw. • Menus, buttons and text are drawn in the app's own style, and now fit properly on every screen size. • The Configure Controller screen fits on a phone, with nothing drawn underneath another button. • The drive-direction switch reads "Swap Drive Direction". DRIVING AND THE FIELD • Toggles turn exactly one face per hit, however hard you hit them. They used to spin freely when clipped. • The practice field starts with its goals loaded and its features spread out, so there's more to drive at. • Fixed a scoring bug where a game piece could not always be handed from the floor intake to the scoring intake. ALSO • Settings ▸ Robot ▸ Show Performance Stats puts a live frame rate, memory and thermal readout on screen.

FAQ

What is RoboSimL?

RoboSimL is a driving practice tool for competition robotics teams. It simulates the exact movement and mechanics of your team's custom-built robots using realistic physics.

Can I use my own robot designs in RoboSimL?

Yes, you can send your robot's CAD files (FBX or URDF) to the developers, and they will build it into a drivable robot within the app for you. This process typically takes a few days.

Does RoboSimL work offline?

Yes, RoboSimL works offline. There is no account required, and all your settings are stored locally on your device.

Does RoboSimL have ads?

No, RoboSimL is completely ad-free. The app also has no in-app purchases or subscriptions.

What kind of controls does RoboSimL offer?

RoboSimL features twin on-screen sticks and customizable mechanism buttons. You can resize, reposition, and reassign button functions to suit your preferences.

How realistic is the robot simulation in RoboSimL?

The simulation is highly realistic, with mechanisms like claws and lifts operating through their real travel. Wheel speed is based on the drivetrain's actual free-spin RPM, and robots have real mass affecting their handling.

What devices does RoboSimL support?

RoboSimL is available for iPhone and iPad devices.

How often is RoboSimL updated?

The latest version of RoboSimL is 1.1, which was released on September 18, 2026. Updates are provided to improve the application.
