L'Unitree Go1 è un robot quadrupede sviluppato per supportare attività di ricerca e sviluppo in autonomia, interazione uomo-robot (HRI), trasporto e mappatura (SLAM). Dotato di un sistema di motori e una struttura altamente stabile, il Go1 è in grado di percorrere terreni complessi con agilità e velocità. Il design versatile e i numerosi accessori disponibili (incluso LiDAR 3D e altri sensori) lo rendono adatto per applicazioni in ambienti accademici, industriali e di esplorazione. Con un peso di circa 12 kg (batteria inclusa) e dimensioni compatte (645 mm x 280 mm x 400 mm), il Go1 può raggiungere una velocità massima di 3,7 m/s (pari a circa 13,3 km/h), a seconda della versione. L’autonomia operativa può arrivare fino a 2,5 ore, con una batteria progettata per un equilibrio ottimale tra potenza e durata.
