R19E (Athena Mk5): Low cost bench top 4-axis cylindrical format robot arm
R19 is a low cost entry to bench top robotics, fast, accurate and reliable and easy to program. It is of the cylindrical format with four axes ideally suited to working in a plane around the robot. Like our other robot arms it is excellent value fast and accurate. The mechanics are incredibly 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. It is easy to apply and program yet is capable of the most intricate tasks. You'll find it a joy to use.
Like all ST robots it uses new light weight, high speed, high efficiency 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.
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. |

Linear Track
![]() |
| R19 may optionally be mounted on a linear track. This has dual crossed-roller linear bearings providing speed and precision along with smoothness and lack of vibration and noise. Max speed 1m/sec. Positional repeatability 0.2mm. R19D pictured on 1m track. |
Workspace
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. |
