A robotic massage system includes a robotic arm that is actuated in order to execute a massage plan comprising a plurality of strokes. It further includes a communication interface that receives feedback from a user affecting the massage plan. It further includes a controller that receives state information during execution of the massage plan and modifies the strokes in the massage plan based on the state information and the feedback.

Spatula gripper

A powered ankle-foot prosthesis, capable of providing human-like power at terminal stance that increase amputees metabolic walking economy compared to a conventional passive-elastic prosthesis. The powered prosthesis comprises a unidirectional spring, configured in parallel with a force-controllable actuator with series elasticity. The prosthesis is controlled to deliver the high mechanical power and net positive work observed in normal human walking.

A control server controls a dual-arm robotic manipulator (DARM) for handling deformable objects in a stack. The control server receives a set of images of the stack captured by a set of image sensors, and determines a contour of the stack based the set of images. Based on the contour and historical data associated with the deformable objects in the stack, the control server determines a sequence of actions to be performed by the DARM for handling a first deformable object in the stack, and controls the DARM to handle the first deformable object by communicating a set of commands corresponding to each action in sequence of actions. The first deformable object is handled such that original form factors of the first deformable object and the remaining stack are maintained.

Method and system for handling deformable objects

A method, system and apparatus including a mechanism capable of performing a variety of operations, each operation having a respective power requirement and a power source capable of providing power to the mechanism at a variety of different levels corresponding to the operations being undertaken by the mechanism where the power source is regulated to at least provide a first lower power level sufficient for one or more operations requiring a lower power level and is increased to provide a higher power level as needed for one or more alternative operations requiring a higher power level.

The present invention provides methods and systems for integrating a procedural computational model with a declarative computational model. For example, in one aspect, the present invention provides a method for integrating a plurality of procedural instructions in a procedural computational system with a plurality of declarative rules in a declarative computational system. In such a method, for each of the procedural instructions operating on one or more variables, a hash table indexed by variable names is utilized to determine whether any of these variables participate in at least one of the declarative rules. Upon execution of a procedural instruction that changes a variable participating in a declarative rule, other variables associated with the rule are updated so as to maintain a relationship imposed by the rule among the variables. The updating of the other variables is performed prior to execution of other procedural instructions.

Upon execution of a procedural instruction that changes a variable participating in a declarative rule, other variables associated with the rule are updated so as to maintain a relationship imposed by the rule among the variables. The updating of the other variables is performed prior to execution of other procedural instructions. Further, for each of the updated values, changes associated with to updated variable are propagated to other rules, if any, in which the updated variable participates. The propagation of the change can be accomplished by modifying values of variables other than the updated variable so as to maintain relationships defined by these other rules. The integrated computational systems of the invention can find applications, for example, in workflow processing.

Methods and apparatus for service-level based and/or skills-based assignment of a work item to one (or more) of a plurality of resources based on fitness, for example, of skills required by the former to those provided by the latter. Assignment takes into account the level of stress on the work item and/or resources, such that the number of resources fit for assignment varies as the level of stress varies. Systems according to the invention can be used, by way of example, to route a call or other request made by a customer to a service center. The requirements for processing the call (determined, for example, by an incoming call operator) are matched against the skill sets of available customer service agents, taking call and/or resource stress levels into account. For example, some implementations may match an incoming call having a low stress factor (e.g., a newly received call from a standard customer) to a smaller pool of agents with both required and desired skills, while assigning a call with a higher stress factor to a larger pool of agents with at least required skills. Other embodiments may match an incoming call having a low stress factor to the larger pool of agents having at least the required skills, while assigning a call with a higher stress factor (e.g., a call from a priority customer) to an agent from the smaller pool of agents who have both required and desired skills.

Methods and apparatus for work management and routing

A method of automated workflow processing includes transforming an object, A1, which is of class X, into an object which is of class Y. The method includes the steps of separating existing data elements of A1 from the object itself, generating new data elements corresponding to class Y, inserting the new data elements into object A1, and computing values for the new data elements, possibly based on values of the old data elements. Other objects that referred to A1 before the transformation continue to do so afterwards. Values of data elements prior to transformation can be preserved, e.g., to facilitate review, to facilitate further transformation, and/or to facilitate back transformation.

Integration of declarative rule-based processing with procedural programming

Systems for controlling the motion of multiple articulated elements connected by one or more joints in an artificial appendage system. Four different embodiments includes a controller that reduces the dimension of joint state space by utilizing biomechanically inspired motion primitives; a quadratic proportional-derivative (PD) controller which employs a two-stage linearization method, applies constraints to variables for dynamic stability, and employs a corrective 'sliding control' mechanism to account for errors in the linear model used; a non-prioritized balance control approach that employs enforced linear dynamics in which all control variables are truncated to linear terms in joint jerks; and a biomimetic motion and balance controller based on center of mass (CM) energetic and biomimetic zero moment conditions.
