R19E bench top 4-axis cylindrical format robot arm

Ideal for laboratories as well as many industrial applications.
New design longer stroke for shorter physical axis length (less overhead)
R19E (Athena Mk5) is a bench-top robot of the cylindrical format with four axes ideally suited to working at bench level around the robot. It is fast, accurate and easy to program. The mechanics are simple and phenomenally reliable; its predecessors have been running 3 shifts a day for a decade without failure, in fact we give a 2 year warranty.

Like all ST robots it uses new light weight, high speed, high efficiency hybrid stepping motors with encoder feedback. The new design (R19E) has the motors mounted to the sides of the axis drives which reduces the physical lengths of the axes compared to strokes (total movement). This makes it even easier to fit in confined spaces such as fume cupboards or lead enclosures.

The package includes the Mk5 controller which is simple and reliable using a partnership of fast CPU and DSP processors and compact micro-stepping drives. Software is ROBOFORTH II which make this robot really easy to get started with yet the most complex motions, interfaces and peripherals may be programmed, assisted by ROBWIN project manager which brings everything together on one screen. ActiveX modules make it easy to integrate into larger systems. Everyone who uses this system agrees it is the most flexible robot software on the planet.

With programmable speed and acceleration, programmable gripper confirmation and intelligent error handling the R19 will carry your expensive sample quickly and safely without spilling or dropping or leaving you wresting it from the gripper in some peripheral.

Workspace is a cylinder approx 1100mm in diameter by 500mm high. (see H and V in specifications above and diagrams below). End effector will affect reach i.e. longer fingers will increase reach. Reach is normally measured to the center-line of rotation of the gripper.
