Robotic workstation

Technical field of the invention

The present invention relates to the field of robotic workstations, and specifically to robotic workstations for use for educational purposes, for demonstration purposes, for use at exhibitions, and to robotic workstations that can easily be moved from one place to another.

Background of the invention

Traditional robotic workstations for use for educational purposes, for demonstration purposes, and for use at exhibitions have the disadvantage that they are unmanageable. Furthermore, the safety legislation in many countries prohibit a single user to lift the weight of a robotic workstation, complicating their transportation.

Object of the Invention

The objective of the present invention is to provide a robotic workstation, which can be managed by a single user.

Description of the Invention

A first aspect of the present invention relates to a robotic workstation comprising:

- a base unit comprising a bottom section with a pair of wheels, and a top section;

- a movable robotic arm with multiple joints, and configured to be coupled to the top section of the base unit;

- a handle a) positioned in close relation to the top section of the base unit or b) retractable to a position in close relation to the top section of the base unit; and

- a longitudinal runner configured for sliding contact with an edge of an obstacle to be passed during transportation of the robotic workstation.

DK 2016 00761 A8

A second aspect of the present invention relates to a robotic workstation comprising:

- a runner configured for sliding contact with an edge of an obstacle to be passed during transportation of the robotic workstation.

A third aspect of the present invention relates to a robotic workstation comprising:

- a sliding unit configured for sliding contact with an edge of an obstacle to be passed during transportation of the robotic workstation.

In one or more embodiments, the bottom section of the base unit comprises the control unit for the robotic arm. The position of the control unit, optionally, in combination with suitable ballast and/or support legs (preferably retractable), prevent the robotic workstation from tilting.

In one or more embodiments, the top section of the base unit and a part of the bottom section of the base unit is configured as a beam, preferably a hollow

DK 2016 00761 A8 beam. This configuration stabilizes the robotic workstation when the robotic arm is operating.

In one or more embodiments, the (longitudinal) runner is positioned between the pair of wheels, and extends upwards towards the top section of the base unit. When sliding the robotic workstation down an obstacle (such as down from a boot or transport compartment of a car) and over an edge (such as the bumper or side rail of the car), this configuration will allow for a smooth transition between the wheels being in contact with the edge and the runner being in contact with the edge. The runner is preferably longitudinal, as the sliding operation will be needed along a substantial length of the robotic workstation.

In one or more embodiments, the pair of wheels and the handle extends beyond the back face of the base unit. When sliding the robotic workstation down an obstacle (such as down from a boot or transport compartment of a car) and over an edge (such as the bumper or side rail of the car), this configuration will allow for a smooth transition between the wheels being in contact with the edge and the runner being in contact with the edge.

In one or more embodiments, the (longitudinal) runner comprises a top layer of an elastic and/or flexible material. Many suitable elastic and/or flexible materials exists, such as rubber, elastomer, carpets, or woven or non-woven textiles. The runner should have a relatively smooth surface in order to allow for the robotic workstation to slide over an obstacle. The surface should also preferably be elastic to avoid damaging the obstacle and/or the robotic workstation.

In one or more embodiments, the (longitudinal) runner is configured as a cord winder.

DK 2016 00761 A8

In one or more embodiments, the (longitudinal) runner is attached to the backside of the robotic workstation, such as to the backside of the bottom section and/or to the top section of the base unit.

In one or more embodiments, the (longitudinal) runner is attached to the backside of the robotic workstation, such as to the backside of the bottom section and/or to the top section of the base unit, and wherein the base of the runner is narrower than its top section (serving as the sliding surface), such that a cord may be wrapped around the base.

In one or more embodiments, the handle comprises one or more wheels. The wheels of the handle and the pair of wheels of the bottom section makes it possible for a user to position the robotic workstation in a rollout position (e.g. within a trunk of a car, i.e. within the main storage compartment), which makes it easier to handle during loading, positioning, and unloading during transportation (e.g. within the trunk). In one or more embodiments, the pair of wheels and the handle extends beyond the back face of the bottom section of the base unit.

In one or more embodiments, the handle further comprises a control pad holder. In one or more embodiments, the control pad holder is attached to the handle, preferably between the wheels; and wherein the handle is configured for being rotated such that the control pad holder may be in a retracted position behind the wheels and in an advanced position, in front of the wheels.

In one or more embodiments, the robotic workstation further comprises a protective cover adapted for covering at least a part of the movable arm segments when the movable arm is collapsed.

In one or more embodiments, the protective cover comprises a horizontal plate configured for covering at least a part of the top face of the bottom section of the base unit, and wherein said cover is adapted for being positioned in an inverted

DK 2016 00761 A8 position, such that the horizontal plate serves as a table top for the movable arm to work on when active. The horizontal plate may comprise fixture holes and/or or work holes for demonstration items.

In one or more embodiments, the top section of the base unit is narrower than the bottom section of the base unit, such that the top face of the bottom section of the base unit may function as a table top for the movable arm to work on when active. The top face of the bottom section may comprise fixture holes and/or or work holes for demonstration items.

In one or more embodiments, the bottom section comprises a compartment with an opening through the upper face of bottom section, and wherein the opening is configured with a cable slot facing the back face of the bottom section; wherein the compartment is configured for holding a control pad for storage.

In one or more embodiments, the robotic workstation comprises means for zeropoint clamping. This configuration reduces the need for recalibration of the robotic workstation.

In one or more embodiments, the base unit, such as the bottom section and/or the top section, comprises means for zero-point clamping.

Zero-point clamps may employ a mounting knob and clamping wedge lock to pull the robotic workstation against the ground face of a zero-point chuck and/or against another workstation. The retention knob sits inside the chuck bore and offers positional accuracy to within a few tenths of an inch and several tons of clamping force until released through mechanical, hydraulic, or pneumatic pressure.

As used in the specification and the appended claims, the singular forms a, an, and the include plural referents unless the context clearly dictates

DK 2016 00761 A8 otherwise. Ranges may be expressed herein as from about or approximately one particular value and/or to about or approximately another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent about, it will be understood that the particular value forms another embodiment.

It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.
