Abstract
A mounting base for supporting and rotating an instrument about two perpendicular axes is disclosed. The mounting base includes a vertical column; a rotatable platform attached to the column by a revolute joint; a rail around the column at least one rod, an end of the at least one rod connections with the revolute joint; at least one sliding mechanism, connecting with the other end of the at least one rod, the sliding mechanism sliding on the rail. The mounting base is light and easily controlled with arbitrary azimuth.

A mounting base for supporting and rotating an instrument about two perpendicular axes, comprising:
- a vertical column;
- a rotatable platform attached to the column by a first revolute joint;
- a rail around the column;
- at least one rod, an end of the at least one rod connecting with the first revolute joint;
- at least one sliding mechanism, connecting with the other end of the at least one rod, the sliding mechanism sliding on the rail.
A mounting base for supporting and rotating an instrument about two perpendicular axes, comprising:
- a vertical column;
- a rotatable platform attached to the column by a first revolute joint;
- a rail around the column;
- at least one extendable linear actuator, an end of the at least one actuator connecting with the first revolute joint;
- at least one sliding, mechanism, connecting with the other end of the at least one extendable linear actuator, the sliding mechanism sliding on the rail.
A mounting base for supporting and rotating an instrument about two perpendicular axes, comprising:
- a vertical column;
- a rotatable platform attached to the column by a first revolute joint;
- a circular rail around the column;
- two rods, upper ends of the two rods both connecting with the first revolute joint;
- two sliding mechanisms, connecting with lower ends of the two rods respectively, the sliding mechanism sliding on the rail;
- wherein the column is located at the center of the rail;
- the two rods are connected with the first revolute joint by universal joints;
- the two sliding mechanisms are connected with the lower ends of the two rods by three-rotational-degrees-of-freedom joints;
- each sliding mechanism includes a gear pair, a servo motor and a reducer attached to the servo motor;
- a rack is provided on the inner lateral face of the rail;
- and one gear of the gear pair engages with the rack;
- the gear pair is driven by the servo motor and the reducer;
- and
- an axis of the column is perpendicular to an axis of the first revolute joint.
