Incheon, South Korea-based TESOLLO Inc. has launched its latest DG-5F-S humanoid robotic hand, a more compact and affordable model built around its own proprietary actuator technology. The hand, weighing under 1 kg (2.2 lb), is designed to accelerate the commercialization of humanoid robots by offering a high-dexterity, platform-agnostic gripper at a lower cost.
While humanoid robots capture headlines for their walking prowess, their ultimate utility often comes down to a simple question: can they use their hands? A startup from South Korea is betting that its specialized expertise in robotic manipulation will be the key that unlocks true functionality. TESOLLO Inc., a company founded in 2019, has unveiled the DG-5F-S, a next-generation robotic hand that shrinks the size, weight, and—critically—the price of sophisticated end-effectors. By moving away from generic, off-the-shelf actuators to develop its own optimized components, TESOLLO is addressing one of the most complex and costly challenges in humanoid robotics.
“Since 2023, TESOLLO has been developing proprietary actuators optimized for humanoid robotic hands, moving away from the use of generic actuators,” stated Youngjin Kim, CEO of TESOLLO, in a report by The Robot Report. This in-house focus on high torque density, durability, and maintainability has culminated in the DG-5F-S. Like its predecessor, the DG-5F, the new model features a biomimetic five-finger, 20 degrees-of-freedom (DoF) design, with each finger having four independently driven joints. The advancements are in the miniaturization and integration: the new hand is both more compact and lightweight, weighing in at under 1 kilogram, making it comparable in size and heft to a human hand for more natural integration onto various humanoid platforms.

Perhaps the most compelling part of the announcement is the strategic price point. TESOLLO says the DG-5F-S will cost about 60% of the price of its flagship DG-5F model. This deliberate move aims to make advanced robotic manipulation accessible to startups, research institutions, and small to midsize companies who might have been priced out by premium alternatives. The hand employs a direct-drive mechanism for high positional accuracy and low backlash, and comes with gripping algorithms for handling diverse objects. According to The Robot Report, it also supports industry-standard communication protocols and offers customization like tactile sensors and waterproofing.
The DG-5F-S made its prototype debut at CES last week, with a full commercial launch planned for the first half of 2026. For TESOLLO, which has already exported its earlier model to 16 countries, this new product is more than an iteration; it’s a calculated play to become a standard component in the burgeoning humanoid ecosystem. By solving the hand problem with a dedicated, affordable, and capable solution, TESOLLO is positioning itself as a critical enabler, helping to push humanoid robots out of research labs and into the real-world tasks they were ultimately built to perform.
