Thank you

Thank you Thank you for choosing the BarrettHand BH8-282 Grasper. The BarrettHand is designed to overcome the inflexibility of conventional grippers with microprocessor-enabled dexterity while maintaining durability, compactness, and ease of use. The BarrettHand is a multi-fingered Grasper with the dexterity to secure target objects of different sizes, shapes, and orientations. Rather than rely on pinching gripper friction or permanent gripper-jaw shape customization the BarrettHand gently envelops the object, securely locking its joints until commanded to release.

System integration with any robotic arm is fast and simple. Even with its low weight (less than 1 kg) and compact form, it is totally self-contained. Communication with the BarrettHand can be achieved using its high-speed Controller Area Network (CAN) Bus for rapid sensor feedback and control, or its RS-232 serial connection for guaranteed compatibility. The BarrettHand features a common cross-platform compatible API and provides powerful on-board motion control through Barrett’s open Grasper Control Language (GCL) facilitating supervisory control.

The compactness and low weight of the BarrettHand assures that the enhanced dexterity does not compromise arm payload. Its low mass and short base-to-grasp-center distance minimize joint loading on the host robot and reduce extraneous arm movements during object reorientation. The custom control-electronics package is contained entirely within the palm shell which reduces electrical wiring to a single cable carrying all communications and motor power.

We hope that you enjoy the versatility and functionality of the BarrettHand. Please do not hesitate to give us feedback or ask for advice when needed. US+617-252-9000, support@…, or
