    3 Thank you for choosing the !BarrettHand BH8-280/290 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.

    5 System integration with any robotic arm is fast and simple.  Even with its low, 1.2-kg, weight 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.

    7 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.

    11 == Improvements over the previous model (BH8-262): ==
    12 * New CANbus control offers > 10x the control rate of RS-232.
    13 * Realtime control now includes torque and position control modes in addition to the standard velocity control.
    14 * All joint positions are tracked, even after TorqueSwitch breakaway occurs.
    15 * The palm height has been reduced by 18 mm, improving end-of-arm agility.
    16 * Absolute magnetic encoders are more robust than the incremental optical encoders of the previous model and offer 10x position precision.
    17 * LEDs on the hand indicate power or error state (error states available soon).
    18 * Locally-controlled sensor/drive loops allow for lead-through programming.
    19 * Programmable over-temperature shutdown with multiple heat sensors.
    20 * Gear shields on “spread” axis help to keep grease in, fingers out.
    21 * Smaller power supply with status LEDs.
    22 * Maximum allowable cable length extended from 3 m to 35 m (using CANbus).
    23 * The BarrettHand Graphical User Interface software has many new features, including: cross-platform compatibility (Windows/Linux), interactive 3D model using OpenGL, and enhanced data collection and graphing capabilities.
     12== Improvements over the previous model (BH8-280): ==
     13* Height of base reduced from 41.5 to 25 mm – distance from palm pad to bottom of hand is only 62 mm.
     14* Weight reduced from 1.2 kg to 0.98 kg.
     15* Power supply efficiency improved; no-load power draw reduced from 7.5 watts to 4.7 watts.
