Robotic hand developer Tesollo Inc. has formally begun preparations for an preliminary public providing, or IPO, within the coming yr and has accomplished its Collection B funding spherical to gas its international growth.
The Incheon, South Korea-based firm focuses on manufacturing core robotic parts, superior finish effectors, and methods designed to reinforce robotic autonomy and human-robot collaboration.
âBy our IPO, we purpose to ascertain a company basis that international prospects can belief and speed up our growth into abroad markets,â acknowledged Younger-Jin Kim, CEO of Tesollo. âBy strengthening our mass-production capabilities and advancing our core know-how growth, we are going to proceed to develop into a worldwide chief within the robotic hand sector.â
Tesollo stated that current shareholders, together with POSCO Expertise Funding, KB Funding, and Enlight Ventures, participated in its Collection B spherical as follow-on traders. Strategic traders from the commercial sector, together with Daesung Hello-Tech and HL Mando, additionally joined the spherical. The corporate claimed that the funding demonstrates recognition of its technological capabilities and progress potential.
Based in 2019, Tesollo added that it’s securing prospects in main markets, together with the U.S., China, and Japan. To this point, the corporate has exported its merchandise to 19 nations, and its abroad gross sales lately surpassed its home gross sales, marking its transition into a worldwide firm.
Tesollo commits to robotic hand growth
In March this yr, Tesollo demonstrated the DG-3 three-fingered gripper and different merchandise at AW 2026. The corporate’s product line ranges from the DG-2F parallel grippers to the five-fingered DG-5F.
Tesollo stated it developed the DG-5F-S utilizing proprietary in-house actuators to weigh lower than 1 kg (2.2 lb.). This mannequin presents excessive precision and stability at about 60% of the price of its predecessor and helps speed up the commercialization of humanoid robots, it asserted.
The corporate was an exhibitor on the current Robotics Summit & Expo in Boston. Tesollo additionally demonstrated the DG-5F-M and DG-5F-S robotic palms, together with teleoperation, bin selecting, in-hand manipulation, and its humanoid vision-language-action mannequin (VLA) on the ICRA present in Vienna.
All of this publicity comes as the corporate has matured its product line with a realistic technique to develop into a specialist in multi-jointed robotic palms for humanoids.
The DG-5F is a robotic hand comparable in dimension to an grownup maleâs hand and options 20 independently pushed joints for superior performance. | Credit score: TESOLLO
Highlight on MTBR
Humanoid manipulation is a tough utility to grasp, because the palms are almost as sophisticated as the remainder of the humanoid physique and limbs. Such end-of-arm tooling (EOAT) is subjected to emphasize and put on that’s greater than that of some other part on the robotic.
Imply time between restore (MTBR) and imply time to restore (MTTR) are two key efficiency indicators (KPIs) for humanoid robotic grippers.
Many customers of humanoids complain of frequent breakage and time spent fixing damaged fingers and joints. Based on an evaluation by ENGtechnica on the humanoid hand bottleneck, this structural complexity creates a disproportionate “failure density” the place dozens of micro-actuators, sensors, and tendon-driven cables act as single factors of failure.
Tesollo stated it acknowledged this subject early in growth. It designed its DG collection to be straightforward to restore and substitute the fingers and joints because the palms fail throughout regular operations. The varied use circumstances for humanoid palms, mixed with the necessity for part longevity, stay difficult for each humanoid hand producer.
At present, no producer is near a licensed 10,000-hour MTBR, and this metric is the important thing measure by which these compact machines can be measured if they will survive industrial and even industrial deployment.
