Heavy capacity arm support systems
Systems and methods are provided for supporting an arm of a user while using a tool that include a harness configured to be worn on a body of a user; an arm support pivotally coupled to the harness for supporting a user's arm; and a tool mount on a free end of the arm support for receiving a tool such that the tool is manipulatable by a hand of user's arm supported by the arm support. One or more compensation elements may be coupled to the arm support and/or the tool mount for at least partially offsetting a gravitational force acting on the user's arm and/or the tool received on the tool mount.
Hybrid terrain-adaptive lower-extremity systems
Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.
Continuous Slip Recovery
The disclosure provides systems and methods for mitigating slip of a robot appendage. In one aspect, a method for mitigating slip of a robot appendage includes (i) receiving an input from one or more sensors, (ii) determining, based on the received input, an appendage position of the robot appendage, (iii) determining a filter position for the robot appendage, (iv) determining a distance between the appendage position and the filter position, (v) determining, based on the distance, a force to apply to the robot appendage, (vi) causing one or more actuators to apply the force to the robot appendage, (vii) determining whether the distance is greater than a threshold distance, and (viii) responsive to determining that the distance is greater than the threshold distance, the control system adjusting the filter position to a position, which is the threshold distance from the appendage position, for use in a next iteration.
METHOD AND APPARATUS FOR ISOLATING A VIBRATION OF A POSITIONING DEVICE
A method and an apparatus for isolating a vibration of a positioning device are provided. The apparatus includes a base plate for the positioning device, at least one active bearing element for bearing the base plate on/at a foundation and at least one evaluation and control device.

The fixed frame unit supports one end of the laminate, and the drive frame unit supports the other end of the laminate, faces the fixed frame unit, and is movable in the driving direction with respect to the fixed frame unit.
Robot with inertia shifting assembly providing spin control during flight
A robot configured to provide accurate control over the rate of spin or rotation of the robot. To control the rate of spin, the robot includes an inertia shifting (or moving) assembly positioned within the robot's body so that the robot can land on a surface with a target orientation and stick the landing of a gymnastic maneuver. The inertia shifting assembly includes sensors that allow the distance from the landing surface (or height) to be determined and that allow other parameters useful in controlling the robot to be calculated such as present orientation. In one embodiment, the sensors include an inertial measurement unit (IMU) and a laser range finder, and a controller processes their outputs to estimate orientation and angular velocity. The controller selects the right point of the flight to operate a drive mechanism in the inertia shifting assembly to achieve a targeted orientation.
