Summary

Tesollo Inc., based in Incheon, South Korea, is a robotic-hand specialist manufacturing core components and end effectors for humanoid and industrial robot manipulation. Founded in 2019, the company has matured from a components supplier into an internationally distributed business — overseas sales recently surpassed domestic sales — and in July 2026 announced it had completed a Series B round and formally begun preparations for an IPO. Its product line spans the two-finger DG-2F parallel gripper through the five-fingered DG-5F humanoid hand, with a specific focus on making its hands practical to repair and maintain given the sector-wide reliability problems affecting multi-jointed robotic hands.

What It Is / How It Works

Tesollo positions itself as a specialist in multi-jointed robotic hands intended to work across embodiments — cobots, industrial arms, and wheeled or legged humanoids — rather than being tied to a single platform OEM. Its product range spans simple two-finger parallel grippers (DG-2F) through a three-finger gripper (DG-3) to full five-fingered humanoid hands (DG-5F family), giving integrators a menu of complexity and cost points depending on task requirements.

DG-5F-S actuator development: The DG-5F-S variant uses proprietary in-house actuators to bring total hand weight under 1 kg while delivering what the company describes as high precision and stability at roughly 60% of the cost of its predecessor — a direct attempt to address the cost barrier that has kept high-DoF dexterous hands out of reach for volume humanoid deployment.

Addressing the industry’s reliability/repairability problem directly: Humanoid manipulation end effectors are subjected to disproportionately high mechanical stress relative to the rest of a robot — a phenomenon industry analysis has termed “failure density,” where dozens of micro-actuators, sensors, and tendon-driven cables packed into a small hand volume each represent a single point of failure. Mean time between repair (MTBR) and mean time to repair (MTTR) are the two key performance indicators the industry uses to track this, and as of mid-2026 no manufacturer — Tesollo included — has achieved a certified 10,000-hour MTBF. Rather than claiming to have solved this, Tesollo has designed the DG series specifically to make fingers and joints fast and easy to replace when they do fail during normal operation, treating repairability as the near-term mitigation while durability technology continues to mature.

Demonstrated capabilities: At AW 2026, ICRA (Vienna), and the Robotics Summit & Expo (Boston), Tesollo has demonstrated teleoperation, bin picking, in-hand manipulation, and a humanoid vision-language-action (VLA) model running on its hands — signaling the company is building a software/AI layer around its hardware, not just selling a mechanical end effector.

Customer and research base: Tesollo’s own site lists an unusually broad customer/research-partner base for a company this size, spanning automotive OEMs (Hyundai, Kia, GM, Toyota Research Institute), electronics manufacturers (Samsung Electronics, LG Electronics), industrial robot makers (Techman Robot, Delta Electronics), and AI/research institutions (OpenAI, Stanford, KAIST, ETH Zurich, University of Toronto, University of Oxford). Samsung Venture Investment is also listed as an investor, consistent with reporting elsewhere that Tesollo originated as a Samsung C-Lab spin-off and is an NVIDIA Inception Program member — direct corroboration should be sought if this relationship is cited as load-bearing for a future claim.

Notable Developments

2026-07: Announced completion of Series B funding and formal initiation of IPO preparations; disclosed exports to 19 countries with overseas sales now exceeding domestic sales.
2026 (ICRA, Vienna): Demonstrated DG-5F-M and DG-5F-S hands performing teleoperation, bin picking, in-hand manipulation, and a humanoid VLA model.
2026-03 (AW 2026): Demonstrated the DG-3 three-fingered gripper and other products.
Prior to 2026: Introduced the DG-5F-S using proprietary in-house actuators, reducing weight below 1 kg at ~60% of predecessor cost.
2019: Company founded.

Supply Chain Position

Tesollo operates at the Integrated Hand Assembly and Micro-actuation layers of the Robotic Hands & Dexterous Manipulation supply chain, developing proprietary in-house actuators for its higher-end hands (DG-5F-S) rather than sourcing all actuation externally.

⚑ Industrial strategic investors: Daesung Hi-Tech and HL Mando — both South Korean industrial/automotive-adjacent companies — joined Tesollo’s Series B as strategic investors, a pattern echoing Schaeffler and Bosch’s direct strategic investment in humanoid OEM Neura Robotics (see Neura Robotics): established industrial component manufacturers are increasingly taking equity positions directly in humanoid-adjacent hardware specialists rather than only supplying components at arm’s length.

Claim Verification

Claim: DG-5F-S offers “high precision and stability at about 60% of the cost of its predecessor”

Status: Unverified (company claim)

Supporting sources:

Company statement reported directly by The Robot Report, a specialist trade publication with an editorial (non-press-release) byline

Refuting / questioning sources:

No independent third-party benchmarking of DG-5F-S precision, stability, or cost-per-unit against the predecessor DG-5F-M has been published
“60% of the cost” is not tied to a disclosed absolute price for either model

Summary: Plausible and consistent with the broader industry cost-reduction trend in dexterous hands, but the specific percentage is a company claim without independent verification.

Claim: No dexterous-hand manufacturer has achieved a certified 10,000-hour MTBF

Status: Partially verified — industry-wide observation, not a Tesollo-specific claim
