TESOLLO unveils dexterous robot hand for humanoids

Korean gripper company TESOLLO unveiled its latest robot hand designed for humanoids: the Delto Gripper-5 Finger (DG-5F). The new gripper will go on sale in March and boasts 20 degrees of freedom (DoF), with each of its five fingers independently operating with four joints, closely mimicking the human hand.

The company designed the DG-5F to address the burgeoning humanoid market where the robot kinematic includes dual arms. All of the other robot grippers in the TESOLLO product portfolio are designed for single-arm use and have no preferred orientation. The new DG-5F, however, comes in both a left-hand and right-hand configuration.

The DG-5F measures approximately 20 cm (7.9 in) in length, which the company said is comparable to an average adult male hand. This lightweight 1.4 kg (3.1 lb) robotic hand delivers a gripping force of up to 7 kg (15.4 lb).

The company has been producing robotic grippers since 2019. Its product line includes hybrid grippers that combine suction and electric parallel technologies, 4-finger grippers designed for complex handling tasks, and task-specific grippers for applications like bundle palletizing and connector assembly.

Built in gripping algorithm

The DG-5F features a built-in gripping algorithm that enables it to handle objects of various shapes and materials. It also supports industrial communication protocols such as Modbus RTU/TCP.

“We are currently in discussions with various distribution partners that have extensive networks in Japan, the U.S., Canada, and Europe,” a TESOLLO spokesperson said. “Additionally, our efforts to secure sales distributors in Asia, including China and Taiwan, have been progressing faster than anticipated.”

The representative added, “Throughout 2025, we plan to participate in at least one international industrial exhibition or robotics-related conference every month. This strategy will enable us to establish numerous regional sales distributors worldwide.”

Learn about humanoids at Robotics Summit & Expo

Humanoids will be front and center at the Robotics Summit & Expo, which runs April 30-May 1 in Boston and is produced by The Robot Report. Aaron Saunders, CTO of Boston Dynamics, is giving the opening keynote on Day 2 of the event. He will discuss the recently redesigned Atlas robot and share his thoughts about the future humanoids.

The first day of the show will feature a panel about the state of humanoids with Pras Velagapudi, CTO at Agility Robotics, Aaron Prather, director of robotics and autonomous systems at ASTM International, and Al Makke, director of engineering at Schaeffler. The panel will explore the technical and business challenges shaping the development of humanoids. It will also share insights from early deployments, what’s on the horizon, and the ongoing efforts to establish safety standards.

The Robotics Summit & Expo brings together 5,000+ developers focused on building robots for a variety of commercial industries. Attendees will gain insights into the latest enabling technologies, engineering best practices, and emerging trends. There will be 200+ exhibitors, 60-plus speakers on stage, 10+ hours of dedicated networking time, a Women in Robotics Breakfast, a career fair, startup showcase, and more. Returning to the show is the RBR50 Pavilion and RBR50 Awards Dinner that will honor the winners of the annual RBR50 Robotics Innovation Awards.
