What Tesollo does

Tesollo Inc. is a South Korean robotics company founded in 2019 by CEO Kim Youngjin, headquartered in Incheon, that designs and manufactures modular robotic grippers and humanoid robotic hands sold under the Delto Gripper Series brand. Its product lineup spans from a single-finger DG-1F and two-finger DG-2F through three-, four-, and five-finger anthropomorphic hands (DG-3F-M/B, DG-4F, DG-5F-M, and the compact DG-5F-S), plus customizable DG-C and DG-V modules, all built around a proprietary direct-drive actuation architecture with in-house-developed dedicated actuators (since 2023) and integrated motor+driver+encoder+reducer joint modules that achieve 0.1° repeatability and 2–3 million+ durability cycles. The flagship DG-5F is a 20-DoF anthropomorphic hand approximately 20 cm long with up to 6–13 kg payload, and the platform exposes ROS2, Modbus RTU/TCP, and EtherNet/IP interfaces plus plug-and-play adapters for Unitree, Roboligent (ROBIN), Enactic (OpenArm), and PNDbotics (Adam-U) humanoids, Manus glove teleoperation, and XELA uSkin tactile sensors.

Tesollo monetizes primarily through quote-based direct hardware sales of the Delto Gripper Series via its multilingual website, complemented by a growing distributor channel (Sungshin Instrument / Mitutoyo in Korea, Beijing Axis 3D in China, with active discussions in Japan, U.S., Canada, Europe and Taiwan) and higher-value Delto Solution automation systems (DS, DS-PICK, DS-PAL, DS-Dual Arm) that bundle grippers with cobot and industrial-robot integrations for bin-picking, palletizing, and dual-arm workcells. Its customer base spans Korean conglomerates (Samsung Electronics, Samsung Display, LG Electronics, Hyundai Motor, Kia, HD Hyundai Robotics, Doosan), Tier-1 research institutions (Stanford, KAIST, ETH Zurich, University of Toronto, University of Oxford), and an expanding footprint across 16+ countries. The company has raised cumulative funding of approximately KRW 8.5 billion plus a ~$3.4M Series A extension in May 2026 from Samsung Ventures, POSCO, Enlight Ventures, KB Investment and others, secured non-dilutive support from KODIT First Penguin and Pre-ICON, Samsung C-Lab Outside, Super-Gap Startup 1000+, the K-Humanoid Alliance, and NVIDIA Inception, and is targeting a technology-special IPO between 2027 and 2028.

Revenue model

1. Hardware product sales (Delto Gripper Series): Primary revenue from selling robotic grippers and humanoid robotic hands: DG-1F, DG-2F, DG-3F-M, DG-3F-B, DG-4F, DG-5F (M/S), DG-C, DG-V. Sold via quote-based direct sales through the company website, regional distributors (Sungshin Instrument in Korea, Beijing Axis 3D in China), and global reseller/distributor network being established in Japan, U.S., Canada, Europe, China, and Taiwan.
2. Automation system solutions and integration: Revenue from Delto Solution automation systems (DS, DS-PICK, DS-PAL, DS-Dual Arm) integrating Tesollo grippers with partner collaborative robots (Techman Robot TM5S, HD Hyundai Robotics industrial robots) for bin-picking, palletizing, picking, and dual-arm industrial automation deployments.

Core offering

Tesollo designs, manufactures, and sells the Delto Gripper Series — a modular lineup of multi-joint robotic grippers and humanoid robotic hands (DG-1F through DG-5F) — alongside the Delto Solution automation systems (DS, DS-PICK, DS-PAL, DS-Dual Arm) that integrate the grippers into industrial cells for picking, palletizing, and bimanual manipulation.

Product overview

Tesollo offers a modular gripper/robotic-hand platform branded as the "Delto Gripper Series" alongside a set of robot automation systems. The platform-plus-modules architecture spans single-finger through five-finger anthropomorphic end-effectors sharing a common direct-drive actuation technology: the DG-1F (single-finger), DG-2F (two-finger electric parallel), DG-3F (three-finger multi-joint, in DG-3F-B and DG-3F-M variants), DG-4F (four-finger), and the flagship DG-5F humanoid robotic hand (DG-5F-M and compact DG-5F-S variants), complemented by a customizable DG-C module. On top of these end-effectors, Tesollo ships automation system solutions — DS, DS-PICK, DS-PAL, and DS-Dual Arm — that integrate the grippers into bin-picking, picking, palletizing, and dual-arm workcells. All products share modular hardware, Modbus/EtherNet/ROS2 connectivity, and developer-mode feedback for research and industrial automation.

Direct peers

• Allegro Hand (Wonik Robotics): South Korean competitor selling the Allegro Hand, a 4-finger 16-DoF dexterous hand widely used in research. Directly comparable to Tesollo's DG-3F/DG-4F/DG-5F line; Wonik is a larger Korean robotics conglomerate, giving it a competing Korean supply advantage.
• Robotiq: Canadian specialist in adaptive 2F/3F grippers and sanding/finishing tools for cobots. Comparable to Tesollo's DG-2F/DG-3F line on cobot-targeted modular grippers and developer-friendly integration.
• RightHand Robotics: US-based gripper/picking specialist with multi-finger underactuated hands and integrated piece-picking systems. Directly comparable to Tesollo on modular grippers and industrial automation deployments (bin picking, palletizing).
• Shadow Robot Company: UK-based pioneer of dexterous anthropomorphic robotic hands (Shadow Hand, 20+ DoF). Directly comparable to Tesollo's DG-5F in humanoid hand dexterity, DoF count, and research-lab customer base, though Shadow Robot has a longer heritage and broader EU research footprint.
• Barrett Technology: US-based pioneer of the BarrettHand (3-finger, 4-DoF, with torque sensing) used widely in research. Comparable to Tesollo's DG-3F/DG-4F on dexterous multi-finger hands with embedded force/torque sensing for research and advanced manipulation.

Emerging players

• RobotEra: Chinese startup developing dexterous robotic hands and humanoid platforms (Star1). Comparable to Tesollo as an emerging dexterous-hand specialist targeting humanoid OEMs, with a stronger China-based humanoid-integration story.
• PNDbotics: Chinese humanoid upper-body platform (Adam-U) that is both a partner (DG-5F integration in cross-country humanoid demo) and a potential competitor. Comparable as an emerging humanoid OEM integrating third-party dexterous hands.

Broad incumbents

• Schunk: German broad-line gripper and automation component incumbent (SCHUNK EGK/EGH parallel and 3-finger grippers). Comparable as an established industrial gripper supplier, but with a much broader portfolio and deeper EU manufacturing footprint than Tesollo.
• OnRobot: Danish end-effector platform offering 2F-3F grippers and a unified One System Solution. Comparable to Tesollo's modular Delto Gripper platform and global cobot integration, but as a larger established incumbent with a wider product catalog.
• Apptronik: US-based humanoid robot company (Apollo) that increasingly develops or integrates its own dexterous end-effectors. Comparable as a humanoid platform Tesollo could sell into, but also a potential competitor if Apptronik insources hands.
