RoboSimL

Drive your own custom robot

Free · Designed for iPad. Not verified for macOS.

Drive the robot before you build it. Send your team's 3D model and get it back as a machine you can actually drive — real joints, real weight, real drivetrain. A driving practice tool for competition robotics teams. Every robot in the app began as a team's own CAD. Each one is rebuilt part by part — real joints, real pivots, real drivetrain geometry — so what you drive on your phone moves the way the machine on the field moves. DRIVE Twin on-screen sticks and a set of mechanism buttons. Pick a robot, tap Drive, and you are on a full-size field with cups, pins and toggles to rotate. MECHANISMS THAT WORK LIKE THE REAL ONES Claws open and close and actually hold a game piece. Cascade lifts and double reverse four-bars run through their real travel. Pneumatic cylinders snap between two positions the way a solenoid does, in the real 25 / 50 / 75 mm stroke classes. Intakes pull pieces in. Nothing here is an animation — each mechanism is a physics joint being driven by a motor model. PHYSICS TUNED AGAINST THE MACHINE Wheel speed is set from the drivetrain's real free-spin RPM. Slam the sticks into reverse and the robot plows to the traction limit instead of stopping dead. Raise a lift and the robot rolls in turns, exactly as a tall robot does. Robots have real mass, and a heavy arm out front changes how the whole thing drives. CONTROLS YOU CAN MAKE YOURS Resize the sticks, change their opacity, drag every button where your thumbs actually are, and reassign what each one does. Switch a mechanism between one-button toggle and two-button hold. Set drive and turn sensitivity. Choose which end of the robot the sticks treat as the front. YOUR ROBOT IN THE APP Send us your robot from inside the app — an FBX exported out of your CAD, or a URDF — and we will build it into a drivable robot and send it back to you. Choose whether it is listed for everyone or unlocked only by a code you pass to your own team. It takes a few days and we tell you when it is done — or tell you what to re-export if the file cannot be made to drive. NO ACCOUNT, NO ADS, NO PURCHASES There is nothing to sign up for and nothing to buy. Your settings never leave your device. The app works offline.

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.
