Direct-Coupled Drive
The Titan Z-drive uses a brushless, beltless motor drive system constructed with high torque, low RPM components directly mounted on the precision lead screw assembly. The rotary encoder and brake are also directly mounted. This design eliminates the need for timing belts and complex pulley systems. These advances eliminate several problems:

• maintenance and failure modes associated with timing belt drives
• positioning errors related to pulley concentricity tolerances
• particulate generation from heavily-loaded, high-speed belts
• brake mode failure paths
• brush commutation and heating vulnerability
• brush wear out and contamination-induced failure modes

Backbone Frame and Linear Bearing Assembly
Gaining support from a backbone frame, the Titan robot provides outstanding structural integrity. A one-piece aluminum extrusion with precisely planarized linear ball slides provides a predictable, rigid and accurate reference plane for mounting the robotic motion assembly. This system is scaleable in length to cover both 200 mm and 300 mm processing requirements for standard or extended travel. The advantages of this construction are:

• enhanced planar accuracy, stiffness and repeatability over the total range of motion
• reduced settling time
• mounting capability from the side, top or bottom

Rotating Mast Drive
The Titan robot features a central rotating mast drive that allows for better path planning. Asyst has maximized this capability by developing software that delivers the most efficient path planning motion available. There are numerous benefits of this design including:

• reduction of lost motion and wasted processing time
• increased precision in synchronicity between the motor encoder and arm position
• faster acceleration rates and control of high inertial loads
• maintenance-free operation via "sealed for life" gearset and bearing

Monolithic Links with Cross Roller Bearings
The Titan robot is constructed of the highest quality materials and components such as proprietary welded tubular arm segments and high capacity cross roller bearings. Each component of the robot was scrutinized for unnecessary complexity. The result is an electromechanical design that is vastly simplified. The reduced number of components and subassemblies includes the unique unibody construction that only the Titan features. This construction provides several advantages, including:

• increased structural integrity
• improved payload capabilities
• excellent sealing capabilities that make this robot ideal for harsh environment processing
