Robiq is the official companion app for robiq kits self-balancing robots. Connect over your own WiFi and the robot becomes something you can read, tune and drive from your phone, no account or cloud, nothing in between. LIVE TELEMETRY A full-resolution render of your robot mirrors its real pitch as it balances, next to a live angle readout and a rolling chart. When it leans, the model leans. When it goes over, it lies on the ground. DRIVE IT A thumb joystick with a proper safety watchdog, plus a rover-mode switch for when you want it to stop balancing and just drive. TUNE IT Ten control-loop parameters on analog dials, arranged the way you actually tune them: Kp, Ki, Kd and pitch offset first, then the motor drive envelope, then the values you set once and leave alone. Turn a dial and the robot responds no save button, no round trip. LIGHT IT Pick a color and the robot's base LED follows: preset swatches for a quick change, a full color picker when you want an exact shade. SET IT UP A guided WiFi handover, join the robot's own network, give it yours, and it reconnects on your home network where you can reach it any time. Prefer to keep things direct? Direct Robot Connect drives the robot on its own access point without handing it a network at all. KEEP IT CURRENT Flash new firmware to the robot over WiFi from the Settings screen. The image is checked before a single byte is sent, so a wrong file fails instantly instead of halfway through. MADE TO LIVE ON YOUR PHONE Light and dark themes that follow your system. Available in English, French, Arabic, Chinese and Spanish. REQUIRES A ROBIQ ROBOT This app controls robiq kits hardware and does nothing without it. Your phone and the robot need to be on the same 2.4 GHz WiFi network, or you can connect straight to the robot's own network.
