Lego 3538 is a programmable robot that can be controlled remotely using an infrared remote control. It features two motors, one for each wheel, and a variety of sensors, including a light sensor, a touch sensor, and an ultrasonic sensor. This allows the robot to navigate its environment autonomously and respond to different stimuli.

The robot can be programmed using a simple drag-and-drop interface, which makes it easy to create complex programs. The robot can be programmed to perform a variety of tasks, such as following a line, avoiding obstacles, and responding to different stimuli.
