The standard RC servo motors only rotate 180° because they were designed for the radio control (RC) car or plane. But this limitation is annoying for robotics application. Hence, the manufacturer made a smart move by introducing the 360º continuous rotation servo motor that able to control with the standard RC signal.

For more info on standard RC servo control, please check the Wiki.

GETTING STARTED WITH ENCODER SENSOR MODULE (SN-ENC-MOD)

T-nuts for aluminium profile 20 series.

The hammer nuts or T nuts can be used for the same purpose as the threaded plates and the aluminium extrusion nuts. They can be inserted into the extrusion slot after assembly. 

Features

• Hammer nut with a step as guiding help and rotation stop.
• Turn in at each position of the profile slot.
• Serration provides vibration resistance and destroys the anodized surface of the aluminium profile for ESD protection.
