South Korean firm unveils robotic hand with human-scale dexterity at under 2 lb

South Korean company Tesollo has unveiled the DG-5F-S, a compact five-finger robotic hand designed for humanoid and industrial robots that offers human-scale dexterity with 20 degrees of freedom (DoF). Measuring 21 cm and weighing just 880 grams (1.94 lb), the DG-5F-S combines high articulation with lightweight design, featuring backdrivable joints that provide mechanical compliance for safe interaction and impact absorption. Tesollo emphasizes integration-first engineering to ensure compatibility with existing robotic systems, marking a shift from research prototypes to practical commercial hardware. For simpler applications, a 15-DoF variant is also available, offering reduced complexity and a smaller footprint. The development of dexterous robotic hands is a competitive and rapidly evolving field, with major players like Samsung Electronics pursuing advanced designs such as tendon-driven systems to mimic human musculature and improve precision. Samsung is also working on tactile sensing technologies to enable robots to detect texture, pressure, and micro-slips, allowing real
