| 10 | | * Beware of situations when the Wraptor™ is stationary and secured on the end of a high-payload robot, but there is other active moving equipment nearby. The Wraptor™ generally will not accommodate and reduce the force of any collision, if it occurs. |
| | 9 | This warranty shall be void and of no force and effect if the Product is damaged as a result of: |
| | 10 | a. neglect, alteration, power fluctuation, or accident |
| | 11 | a. improper use, including failure to follow operating instructions or maintenance and environmental conditions prescribed in the User Manual |
| | 12 | a. service or repair by anyone other than service representatives qualified by Barrett and acting in accordance with Barrett's service requirements |
| | 13 | a. use of supplies or parts other than those distributed by Barrett. |
| | 14 | a. use of the Product with incompatible robot arms, computers, peripheral equipment or software |
| | 15 | This warranty shall not extend to any Product on which the original identification marks or serial numbers have been defaced, removed, or altered. |
| 14 | | * Beware that the sharp finger-nail like claws attached nominally to the outer links can cause pain and possibly cut bare human skin depending on details of the grasp. |
| | 19 | This warranty, while valid, shall provide the following: |
| | 20 | a. replacement or repair, at Barrett's discretion, of any defective part, without charge |
| | 21 | a. unlimited technical support |
| | 22 | a. software and firmware upgrades for the Product |
| | 23 | a. latest electronic copies of the manuals |
| 22 | | * Never allow power to be connected to the communication pins at the input connector of the Wraptor |
| 23 | | |
| 24 | | * Do not exceed the load limit of the fingers, 50kg per finger. Consider all loading situations including accelerated loads, cantilever loads from long objects, robot collisions, active loads, etc. (See also, next paragraph.) |
| 25 | | |
| 26 | | * Similar to the concerns about Human safety when the Wraptor™ is mounted on a robotic arm, one must recognize that, for example, a 50-kg lift robotic arm is easily capable of producing several tons (!!!) of force even when moving slowly (in many configurations with high mechanical leverage) or when moving quickly just before a collision (regardless of configuration). Since forces cannot be seen by eye, any contact with rigid surfaces or even with the base or other links of the robotic arm can easily exceed tons of force without operator awareness. It is advisable to be very cautious when running the full system to minimize these collisions or to ensure that a force/torque sensor or collision-break-away mechanism is installed between the tool-plate of the robot and the base of the Wraptor™. |
| 27 | | |
| 28 | | * Do not allow the Wraptor™ to be exposed to corrosive liquids that may cause damage to the body or cable of the unit. |
| 29 | | |
| 30 | | * The operating temperature of the Wraptor™ is monitored continuously and automatically so that no Puck can approach OTEMP, which is set nominally to 82 C. If the temperature reaches within 16C of OTEMP, then the max command torque (motor current) will be temporarily limited to prevent damage. Under normal conditions, the Wraptor™ operates between 35 and 60C. The Wraptor™ was designed with non-backdrivable finger joints to take advantage of the motors’ peak operating performance in short bursts. The spread, however, is backdrivable to aid in target-independent grasping and requires constant motor current to actively hold position. Idling the spread motor (thus activating the spread brake), when possible, will help keep the temperature lower. |
| 31 | | |
| 32 | | * Do not immerse the Wraptor™ in liquid. |
| 33 | | |
| 34 | | * Do not expose the Wraptor™ to corrosive liquids. |
| 35 | | |
| 36 | | * Do not expose the Wraptor™ to mud or slurries. |
| 37 | | |
| 38 | | * Ensure that the electrical Wraptor™ cable and connector cannot be damaged by collision, cutting, pulling, or twisting. |

The subscription service may be purchased for any length of time with the initial Product purchase. If the warranty or subscription service expires, there is a subscription service start up fee of 10% of the original total sale value to pay for a service check. If the service check indicates needed repairs, the customer must pay for repairs before the subscription service may be renewed. |
