TI debuts TI-Rover BT classroom robot

Texas Instruments (TXN) has introduced the TI-Rover BT, a Bluetooth-enabled robotic vehicle designed to bring mathematical concepts into physical space. The classroom-focused device transforms algebraic equations and functions entered on compatible graphing calculators into motion on the floor, turning the room into a coordinate plane. It is available for purchase through instructional dealers nationwide.

The TI-Rover BT connects wirelessly via the TI Bluetooth Adapter and is currently compatible with the TI-84 Evo graphing calculator. Texas Instruments (TXN) plans to extend compatibility in 2027 to the TI-Nspire CX II and TI-Nspire CX II CAS graphing calculators, broadening its use across existing calculator platforms in schools.

The TI-Rover BT is built to convert abstract mathematics into visible and tangible outcomes for students. By entering equations on the calculator, users can command the robot to trace mathematical functions and geometric shapes using built-in Math Drive library templates. The vehicle uses high-precision stepper motors and an onboard pen holder with up and down capability to draw curves, formulas, and patterns on chart paper or other surfaces.

The system supports exploration of rate, distance, and time, enabling teachers to link algebraic plotting with introductory physical science topics. Students can program the vehicle to create visual representations of continuity, discontinuity, and other concepts as the robot moves and draws, helping to connect symbolic expressions with spatial patterns.

Beyond plotting functions, the TI-Rover BT includes features intended to deepen interactive learning and basic robotics exploration. It incorporates an Ultrasonic Ranger that measures distance to nearby objects, enabling the device to respond to its surroundings. Students can program behaviors based on this sensor, such as changing actions when the vehicle approaches an obstacle.

An onboard RGB LED can be programmed to change colors, including in response to readings from the Ultrasonic Ranger. This allows learners to experiment with input and output relationships, linking sensor data and visual feedback to the calculations executed on the calculator.

The TI-Rover BT extends Texas Instruments’ established presence in math and STEM education. Alongside its core semiconductor operations, the company develops and manufactures graphing calculators and education technology products for science, technology, engineering and mathematics instruction. By leveraging existing calculator platforms like the TI-84 Evo and the planned TI-Nspire CX II family support, TI positions the TI-Rover BT as an accessory that integrates into current classroom toolsets.

Teachers and students can use the TI-Rover BT to shift lessons from purely theoretical work on screens to collaborative, floor-based activities. With calculator control, pen drawing capabilities, programmable LEDs, and distance sensing, the product is structured to support a range of math and introductory STEM projects within school environments.
