This exhibit features two electromechanical robot arms that measure approximately 39” long  from the tip of the fingers to the base of the shoulder pivot assembly. The arm has pressure sensitive and end of travel limits, and can adapt to any arrangement of objects stacked in it’s path. It is made of light weight 6061 Aluminum. This arm is totally open framed for educational viewing and based closely on the proportions of an actual human arm. It is especially designed with safety features and force limits The arm is also useable for any age range of visitor. To see examples of our arms click here.  Each arm has five ranges of motion  and movement in 3 fingers.  Our arms have been used as a low cost exhibit robotics device since 1993. The basic design for the arm has also been used in rehabilitation robotics experiments where it provided dexterity, durability and a somewhat human appearance.

As seen in the top view diagram to the left, the arms are placed so that each one is in an adjoining corner. This allows the arms to pass one another without physical contact, but still allows visitors to pass cubes back and fourth at maximum arm extension.

Our robot arms are a durable cost effective and easy to maintain solution to your exhibit robotics applications. All the major components for the arm and controls are “off the shelf” items for your maintenance and repair convenience. We build each arm with a combination of aluminum, nylon, steel, commercial and industrial components and durable exhibit cases. You will never see a pressed wood product come from our workshop. Our control panels are built to take the rigors of public use with thick aluminum tops and quality switches and controls.  The exhibit is designed to be visually stunning, educational and useable by virtually any age of museum visitor.  This exhibit  is view able from all sides making it ideal for mid floor locations. The cubes are made of colored foam material to reduce impact stresses between arms and base panel.  The swing of each arm creates a theoretical null spot on each side. To compensate for this, the triangular shapes tilt any blocks that land in a null spot to a reachable angle. This is also done directly around the shoulder pivots. Each arm is protected by limit controls and spring loaded for shock. The limit controls use simple logic to avoid over travel, as opposed to expensive and hard to repair computer guided systems. The fingers operate by pressing a push switch. The wrist, shoulder and elbow ranges of motion are operated by two joystick assemblies per arm.  The exhibit is configured as a demonstration arm to illustrate remote handling applications for robotics. Remote handling robots are used by industry, aerospace and commercial establishments to extend human capabilities in hazardous situations.
    If you have been troubled by Robotic exhibits that  are extremely high cost or are hard to maintain and require highly skilled personnel and expensive repairs, we can provide the quality alternative. We will build a complete exhibit including  quality built electronic-electromechanical robot arms, fully enclosed exhibit case for the arms, support electronics, visual support materials, maintenance information and schedule, activities  and control panel. Approximate size of case 70" high x 95" wide x 38" deep.  Exhibits are available in a wide variety of colors. Let us know your preference.

7-year warranty against defects in our workmanship; Free Life-time phone/internet technical support; Life-time parts supply sourcing for our exhibits at wholesale prices. See more details below.

Our exhibits have a long service life expectancy, with many units still functioning smoothly at 10 years plus. They are so easy to maintain and repair, that it usually takes regular museum staff only 15 to 20 minutes.
