This build is for the assembly of the DDT 500 Tilt Kit. This assembly is part of a larger build to construct a robotic arm aimed to aid interpreters performing sign-language. The tilt kit is used to perform elbow functions of the arm. It can rotate 180 degrees about the top plate of the tilt kit. The kit was purchased from Servocity online. Please note that the top base plate will not be used in this assembly because the tilt kit will be attached to another component of this project, at the point where the top base plate would be assembled.

Supplies

(5) ABS Parts for Frame
(1) Hitec Aluminum Horn
(1) 1/4” ABS Spacer
(1) 1/4" Bore Flanged Bearing
(1) 1.25" Aluminum Standoff
(1) 0.5” Aluminum Standoff
(2) #4 x 1/2" Flat head Phillips Screw (Black)
(2) #4 x 1/2" Phillips Pan Head Screw (Black)
(4) #4 x 3/8" Truss Head Phillips Screw (Self Tap)
(11) 6-32 x 3/8" Pan Head Machine Screw
(1) 1-1/2" - 8 Hex Bolt
(1) American Dish Service 098-2404 Washer
(1) 1-1/2" - 8 Hex Nut

Step 1: Side Plate Assembly #1

Insert (4) 6-32 x 3/8" Pan Head Machine Screws through the holes on the rough side of the ABS plate. Next place the hitec horn on the opposite side of the ABS plate with the spline of the horn facing outward. Using a screwdriver, secure the screws in the aluminum horn.

Step 2: Side Plate Assembly #2

Insert a 6-32 x 3/8" Pan Head Machine Screw through the rough side of the ABS plate. Attach the 1/2" aluminum standoff to the screw and secure. The standoff is now standing on the smooth side of the ABS plate. Insert the 1/4" ABS spacer through the aluminum standoff.

Step 3: Base Plate Assembly

Place the washer onto the rough side of the ABS Plate and insert the bolt through the hole. Secure in place with the nut. This assembly is used to mount the entire arm to the presentation platform.

Step 4: ABS Vertical Plate Assembly #1

Insert the 1/4" Bore Flanged Bearing on the rough 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 5: ABS Vertical Plate Assembly #2

Install the 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.

Step 6: Base and Vertical Assembly

First press the ABS Vertical Plate Assembly #1 onto the base plate and secure with (1) #4 x 1/2" Pan Head Phillips Screws. Next press the ABS Vertical Plate Assembly #2 onto the 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 7: Final Assembly Plates

With the spline facing the servo output gear, insert the Side Plate Assembly #1 into the servo output gear. Finally insert Side Plate Assembly #2 through the ABS Vertical Plate Assembly with the ball bearing. The unit is now fully assembled and ready for use!
