Abstract: A vertically driving marking robot includes a robot body; at least one magnet constraining the robot to move parallel to a vertical, magnetically responsive surface; a drive configured to displace the robot relative to the surface while the robot is held to the surface; a holder configured to hold a marker; an accelerometer measuring a gravity vector; a computing device in communication with the optical sensors, the accelerometer, and the drive. The computing device includes a processor and computer-readable memory, wherein the computer-readable memory includes non-transitory program code for at least one of the following actions: (a) generating a drift correction to compensate for drive slippage drift in response to and as a function of the gravity vector and (b) commanding the drive to displace the robot along a desired trajectory in response to the drift correction.

These systems include applying the stimulation through via a mattress having a passive section and an active section, a plurality of focal stimulators, and/or an array to apply the stimulation are also disclosed. These devices include a mattress with an active region and a passive region, a stimulating array do deliver targeted stimulation, and a plurality of stimulators to apply focused stimulation.

Abstract: In a method for interactive marking by a mobile robot on a vertical surface, a mobile robot that includes a sensor and an actuated marker is displaced across a vertical surface. Features on, in or behind the vertical surface are detected with the sensor. Displacement of the mobile robot and actuation of the actuated marker is controlled in response to the detection of these features.

Abstract: An orthosis system includes an orthotic device adapted to be worn on the hand of a subject that includes at least one brace component coupled to one or more fingers of the hand and including at least one joint permitting movement of one or more fingers. One or more actuators can be connected to each joint to cause movement of the joint. A control unit can be provided to control each of the actuators to control the movements of each joint separately. The control unit can be operated by the subject or a clinician to facilitate everyday tasks or for treatment or therapy.

Abstract: A modular robotic teaching tool including a plurality of modules that may be operated, for example, to play robot soccer, for introducing principles of mechanical engineering and robotics to prospective students. The teaching tool includes a modular robot that may be assembled in a plurality of configurations. The modular robot includes a body portion, first and second motors, first and second motor mounts, at least three wheels, two of which are mountable to the motors, at least one flipper module, and a remote control module for actuating the motors and the flipper module. The modular robot is advantageous in that it provides for an inexpensive, challenging, and entertaining introduction to some of the principles of robotics and mechanical engineering.

Abstract: An automated workstation capable of continuous, non-stop processing of specimens includes an environmentally controlled storage area that holds multiple cassettes containing specimen plates. A robotic arm for processing the specimens, e.g., by grasping the plates, moving them from the cassettes to other apparatus contained within the workstation, and placing the plates back in the cassettes. An interlock mechanism prevents the operator and robotic arm from simultaneously accessing a cassette. Novel robotic arms, robotic arm positioning mechanisms, plate handling mechanisms, effector tip/plate washing mechanisms, thin-walled pipetters, back-flushing mechanisms and fluid level detection mechanisms, as well as methods for operating the same, facilitate continuous operation of the workstation along with compactness, high throughput and high accuracy of operation. Narrow, thin-walled capillary-like pipetters serve as both means for acquiring and processing small quantity specimens with high precision.
