Description

LEGO NXT robots can be programmed in Java with a replacement firmware and supporting toolchain. It is useful for robotics classes, hobby projects, and developers working with older NXT hardware.

Firmware replacement can change device behavior and may require recovery steps if flashing fails. Follow device instructions carefully and keep batteries charged during firmware operations.
