An ER fluid valve includes a housing and a plurality of parallel flow passages through the housing each defined by spaced electrodes at least one of which is controllable independently of other flow passages electrodes. A controller is configured to selectively establish electrical fields for all of the independently controllable electrodes to close all of the flow passages to ER fluid flowing through the housing. By removing the fields from all of the independently controllable electrodes, all the flow passages are open to the ER fluid flowing through the housing. By establishing fields for select independently controllable electrodes to close their associated flow passages and by leaving other flow passages open, restricted flow of the ER fluid through the housing is accomplished to vary the flow rate through the housing.

A robot includes a chassis, a motive subsystem configured to maneuver the chassis, a hopping actuator attached to the chassis and configured to launch the robot, and at least one leg pivotable with respect to the chassis to pitch the chassis upward at a selected launch trajectory angle. A control subsystem automatically actuates and controls the motive subsystem when the robot is airborne and uses the rotational momentum of the motive subsystem to control the attitude of the robot chassis in flight.
