Claim:
1. A device comprising: a housing defining a cavity; a force sensor; a first hydraulic actuator positioned in the cavity, wherein the first hydraulic actuator moves between a first relaxing mode and a first thrusting mode along a longitudinal axis of the first hydraulic actuator based at least in part in response to sensor data from the force sensor; a second hydraulic actuator positioned in the cavity, wherein the second hydraulic actuator moves between a second relaxing mode and a second thrusting mode along a longitudinal axis of the second hydraulic actuator based at least in part in response to sensor data from the force sensor, and wherein the longitudinal axis of the first hydraulic actuator is substantially parallel to the longitudinal axis of the second hydraulic actuator; a first actuated member coupled to the first hydraulic actuator, wherein the first actuated member is in a first open mode when the first hydraulic actuator is in the first relaxing mode, and wherein the first actuated member is in a first closed mode when the first hydraulic actuator is in the first thrusting mode; a second actuated member coupled to the second hydraulic actuator, wherein the second actuated member is in a second open mode when the second hydraulic actuator is in the second relaxing mode, and wherein the second actuated member is in a second closed mode when the second hydraulic actuator is in the second thrusting mode; a first hydraulic channel in fluid communication with the first hydraulic actuator; a second hydraulic channel in fluid communication with the second hydraulic actuator; and a removable sealing component movable between a sealed position and an open position, wherein the first hydraulic channel is in fluid communication with the second hydraulic channel when the removable sealing component is in the open position such that a pressure applied to the first hydraulic actuator is equal to a pressure applied to the second hydraulic actuator, and wherein the first hydraulic channel is sealed off from the second hydraulic channel when the removable sealing component is in the sealed position such that the first actuated member and the second actuated member are individually controllable.
