A robot includes a main body and a cart that includes a wheel and is capable of coupling to the main body. The main body includes an insertion that is inserted into the cart when the main body is in a coupled state with the cart. The cart includes a brake mechanism that switches between a brake state in which a brake is applied to the wheel and a free state in which the brake is not applied to the wheel. In the brake mechanism, during the coupled state, the free state is maintained by the insertion, and when the coupled state is released and the insertion is removed from the cart, the free state is switched to the brake state.

A welding sled, comprising a support base comprising one or more attachment points for attachment of a wire supply support and attachment of a wire drive assembly; a plurality of rollers coupled to a bottom of the support base; and a brake configured to selectively brake the welding sled.

A patient support apparatus having a central dual control system of casters with an actuating pedal. Two opposite casters are connected by a control shaft with hexagonal cross section. Both control shafts are mutually coupled via a connecting member to a linkage rod. A servomotor with a rack is coupled to the linkage rod. The servomotor is configured to change a position of the rack of the servomotor and thus change a position of the central dual control system of casters upon manual change of position of the actuating pedal and/or upon electrical activation of the servomotor to change a position of the actuating pedal to another position of the central dual control system of casters.

The present invention relates to a bumper system of an agricultural machine, comprising: a plate pivotably connected to a chassis of the machine, movable between an initial position and a contact position; a bar movable between an initial position and an activation position;
the bumper system being configured so that, in the event of the bar coming into contact with an obstacle, the bar moves from its initial position to its activation position, the bar actuating a control member configured to control an emergency sequence of the agricultural machine, the bumper system being further configured so that, in the event of the plate coming into contact with the obstacle, the plate pivots from its initial position to its contact position.

A parking brake system. The parking brake system may include a braking assembly frame having a front end portion and a second end portion; a pressure bar disposed at the second end portion of the braking assembly frame, wherein the pressure bar may be configured to apply a braking force to a tire in a first state and to remove the braking force in a second state; and a braking control actuator operatively linked to the braking assembly frame, wherein the braking control actuator may be configured to cause the braking assembly frame to move the pressure bar between the first state and the second state.
