Single Axis Manipulator Controller

The SOLO is an extremely easy to operate single axis controller capable of running any single axis from Sutter’s line of stepper motor manipulators. The compact design of the SOLO controller requires minimal bench space and provides quiet, fan-free operation.

The SOLO controller features user defined Home and Work positions. Press and hold the Work button to quickly store a work position; press Work again and the manipulator will return to the same location. Home sends the manipulator to an initial location or any user defined position. Position coordinates, in relative or absolute values, are displayed directly on the ROE. A Pulse button activates a discrete 3 micron movement of the axis.

Speed of movement is determined by how fast the ROE knob is turned. We have added three distinct speeds to give the user extreme control over movement. The combination of three speeds and the knob speed control makes the SOLO an ideal, ultra-reliable controller for sub-micron movement.

Single axes are available in lengths of 25 mm or 50 mm. The SOLO is suitable for in vivo experiments that require only one motorized axis. Additionally, this single axis controller can be used as a sub-micron focusing system as seen in the Sutter SOM and BOB microscopes or used to add a fourth axis to your existing Sutter manipulator to create a true four-axis motorized in vivo and in vitro manipulator (such as the QUAD).

USB connectivity and open source commands, along with built-in features such as Work & Home positions, and Pulse mode, make this single axis controller the ideal device for the do-it-yourself scientist.
