The Ryze Tello is a teleoperated compact quadcopter drone developed by the Chinese technology companies Ryze Tech and DJI.
The Tello was announced at CES in January 2018 and released in Asia the following month.[1][2] A collaboration between Ryze Tech and DJI, the Tello is a 80 g quadcopter with a strong resemblance to the larger DJI Spark.[1] The drone has a 5-megapixel camera capable of shooting 720p video.[3]
A programmable version of the Tello, the Tello EDU, was released in November 2018 for STEM programs. The Tello EDU is compatible with the Python, Scratch, and Swift programming languages.[6][7] Another educational Tello variant was released in May 2021 under DJI's RoboMaster brand as the Robomaster TT (Tello Talent).[8] Like the EDU, the Robomaster TT can be programmed with Python, Scratch, and Swift, which can be used to manipulate the latter's new 8×8 LED display.[8][9] The Robomaster TT also has a built-in ESP32 microcontroller and an infrared time-of-flight sensor.[10][11]
In January 2024, DJI announced the discontinuation of its educational products, including the Tello and Robomaster series, in the United States.[12][13] The company had already ceased sales of these products in Asia in December 2023.[14]
