About Tesollo
Robotic hands built for the humanoid era
Founded in 2019 and based in South Korea, Tesollo develops the DELTO Gripper line — a series of anthropomorphic robotic hands recognized for high-DoF design, independent joint control, and integration with humanoid robot platforms. Tesollo is a Samsung C-Lab spin-off, an NVIDIA Inception Program member, and a K-Humanoid Alliance component supplier. Customers include Samsung Electronics and Delta Electronics.
Through Knoxlabs, US and Americas customers can procure Tesollo hardware, bundle it with MANUS and SenseGlove data gloves, and receive deployment support — without the complexity of cross-border sourcing.

Applications
Where Tesollo hands are deployed
From humanoid robot research labs to industrial automation cells and in-hand manipulation studies — Tesollo's DG-5F line is built for environments where dexterity is the critical capability.
Humanoid Robot Research
Lightweight, sub-1kg form factor and compact footprint make the DG-5F-S ideal for studying and developing humanoid robots with advanced manipulation capabilities.
In-Hand Manipulation
20 DoF independent joint control enables fine manipulation tasks — object assembly, connector fastening, in-hand reorientation, and precise tool handling.
Tool Use & Dual-Arm Tasks
Adult-male hand sizing and high payload (DG-5F-M) make Tesollo hands well-suited for tool utilization and coordinated dual-arm operations on humanoid platforms.

FAQ
Frequently asked questions
Common questions about the Tesollo DELTO Gripper line. For pricing, lead time, or anything not covered here, contact Knoxlabs directly.
What is included with the DELTO Gripper?
All DELTO Grippers ship with the following components:
5-Finger DELTO Gripper · Gripper Cable (power cable) · Ethernet Cable (3M) · Bolt Set · Adapter Frame · 4GB USB (sample program & user manual).
How can I control the DELTO Gripper?
The DELTO Gripper offers two control modes:
1. Operator Mode — The gripper has a built-in controller that allows operation through Modbus Protocol. Users can easily control the gripper by modifying the register map.
2. Developer Mode — Direct control of each joint. The built-in controller is bypassed, and users can control the gripper with a custom-developed controller.
What communication protocols are supported?
Operator Control Mode supports Modbus RTU (RS-485) and Modbus TCP (TCP/IP), where the gripper functions as a Modbus Slave (Server).
Developer Control Mode operates over TCP/IP and uses a proprietary protocol provided by Tesollo, with the gripper functioning as a Server.
What is the positional accuracy of the motors?
The positional accuracy of the motors is ±0.1°. However, since each finger consists of multiple serially connected motors, accuracy at the fingertip may vary and could be greater than ±0.1° depending on conditions.
What is the communication cycle of the gripper?
The communication cycle between the gripper and the controller is at least 400 Hz. This may vary depending on the specifications of the controller (PC or other devices).
Does the DELTO Gripper support ROS and ROS2?
Yes, the DELTO Gripper supports both ROS and ROS2. Since ROS is no longer officially maintained, future updates and new product lineups will support ROS2 only — Tesollo recommends ROS2 for compatibility with future developments.
GitHub repository: github.com/Tesollo-Delto (refer to the README for usage instructions).
Is a kinematic model of the DELTO Gripper available?
Yes, customers who purchase the gripper will receive a dummy model in STEP file format along with DH-Parameters. Contact Knoxlabs for kinematic model files.
Can the fingertip be modified for the working environment?
Yes, modifications are possible. The default fingertip material is silicone, but it can be modified according to the hardware specifications of the gripper. Tesollo provides customized fingertip modification services tailored to specific environments — modification costs vary depending on the requirements. Contact Knoxlabs for details.
Which robots are compatible with the DELTO Gripper?
The DELTO Gripper integrates with collaborative robots (cobots) and industrial robots. The adapter frame supports ISO 9409-1-50-4-M6 and is compliant with the ISO 9409-1 international standard.
If your controller supports the Modbus Protocol (Master/Client function), the integration process will be easier. For humanoid platforms, custom mounting adapters may be required (additional cost).
What certifications and IP rating does the DELTO Gripper have?
The DELTO Gripper DG-3F model is certified with CE, FCC, and IP3X. The DG-5F line carries an IP3X protection rating. Confirm certification details for your specific model with Knoxlabs at time of order.
What is the warranty and service period?
The standard warranty period is 1 year. Damages caused by user negligence are not covered under warranty, and repair costs are charged separately. Consumable parts, surface scratches, and wear from usage are not covered. For after-sales support, repairs, and any extended service options, contact Knoxlabs.
