I used a scroll saw today to cut the legs of a tensegrity robot.

It is a product of REXON company and can control the speed. It operates at 220V and uses 125W of power. The product name is VS4005A.

In the picture below, the left side is the power button and the right side is the rotation lever to adjust the speed.
