SPT200 Pan & Tilt Kit

Introduction: SPT200 Pan & Tilt Kit

This build is for the assembly of the SPT200 Pan & Tilt Kit. This assembly is part of a larger build to construct a robotic arm aimed to aid interpreters performing sign-language. The pan and tilt kit is used to perform wrist functions of the arm. It can rotate both horizontally and vertically 180 degrees. The kit was purchased from Servocity online.

Step 1: Base Mount Assembly

Attach the 1/2" Bore Flat Bearing Mount to the rough side of the ABS plate as seen in the picture with (4) 6-32 x 3/8" Pan Head Phillips Head Screws. Next, attach (4) 0.625" Aluminum Standoffs to the smooth side of the ABS plate using (4) 6-32 x 3/8" Pan Head Phillips Head Screws. Then, slide the Servo Shaft Hub through the 1/2" Bore Flat Bearing Mount. Finally, attach the servo to the 0.625" Standoffs using (4) 6-32 x 3/8" Pan Head Phillips Head Screws. Be sure to obtain correct alignment of the servo before tightening down the screws. Secure the servo to the Servo Shaft Hub with the stock servo screws.

Step 2: Pan Servo Mount Assembly

Attach the H-Shaped ABS tilt base plate on top the servo shaft hub using (4) 6-32 x 3/8" Pan Head Phillips Head Screws. Secure the screws properly.

Step 3: Bearing Installation

Insert the 1/4" Bore Flanged Bearing on the textured side of the ABS plate as seen in the picture. Next, press this plate onto the pan servo base plate. Secure with (1) #4 x 1/2" Pan Head Phillips Screw.

Step 4: Tilt Servo Installation

Install the tilt servo into the smooth side of the ABS Plate as seen in picture. Using (4) #4 x 3/8" Truss Screws, secure the servo to the ABS Plate. Next, press the servo plate onto the pan servo base plate and secure with (1) #4 x 1/2" Pan Head Phillips Screws. Finally insert the 1.25" Aluminum Standoff between the two vertical ABS plates. Secure using (2) 6-32 x 3/8" Pan Head Phillips Head Screws.

Step 5: Servo Horn Installation

Attach the servo horn to the smooth side of the ABS plate as seen in the picture with the spline of the servo horn facing outward. Insert (4) 6-32 x 3/8" Pan Head Phillips Head Screws through the rough side of the ABS plate into the servo horn. Secure properly.

Step 6: Attach to the Tilt Servo

Place the assembled servo horn onto the tilt servo output gear. Secure using the stock servo screw.

Step 7: Attach Standoff Into Bearing

First, place (1) 0.5" Aluminum Standoff onto the smooth side of the ABS plate as seen in the picture. Secure using (1) 6-32 x 3/8" Pan Head Phillips Screw. Next, place (1) 1/4" ABS spacer and (1) 1/8" Nylon spacer on the 0.5" Aluminum Standoff. Insert this assembled component into the vertical ABS plate through the bearing.

Step 8: Attach Top Plate

Press the top plate onto the two previously assembled ABS plates. Secure with (2) #4 x 1/2" Flat Head Phillips Screws. The unit is now fully assembled and ready for use!
