ROBOT ASSEMBLY

Base Assembly

BASE

File off raised tabs on each side of Servo.

Place Servo in vice between Fibre Clamps.

Raised Tabs

Repeat process for other 2 servo’s

Base Assembly

File slot on base to size so that servo fits in tightly.

Turn Servo so that Spindle is nearest to semi-circular end.

M4 Set Screws

Base Assembly

M4 Nuts used to secure servo in position

Feet

Thread one end of each of the 5 legs M5

5 Legs

M5 Set screws used to secure 5 legs.

Circular Disc Assembly

Select the attachment shown from the servo pack and attach to circular disk as shown.

Use screws supplied with servo to attach it to disc.

Watch the position of this hole *

Vertical Up-Right

Vertical Upright positioned as shown and glued using Liquid Solvent Cement.

Important: Upright fitted so that it is flush with underside of disc.

Do not attach to base until instructed!

Hole on this side

Stabilising the base Using an M4 x 20 and two M4 nuts, one of the nuts to be placed above disc and the other below

4 stabilising set screws and nuts in place

Fitting Servo to Up-Right

2 M4 screws and nuts used to fix servo to Vertical Up-Right.

Notch facing towards back

Horizontal Arm

Hole at top of Arm

Gripper

M2 screw and Locknut to secure Gripper pivot in place.

Gripper

Glue both parts together.Be careful not to glue

pivot point!

Narrow side to the top

Locknut

Back Servo Motor assembly

Spindle of servo facing back of robot

M3 x 20 Set screw used with 2 nuts, one nut infront and one behind

M4 x 10 Set screw and nut

Assemble of Circular Disc onto Base

Position Base as shown

NB: Rotate Spindle of Servo Motor fully clockwise until it stops rotating.

Attach disk and Up-right to servo as shown. Vertical upright should be Parallel to Back edge of base.

Secure Disc to Servo

Use Servo Screw supplied to secure Disc to Servo.Do not over tigthen.

Adjust stabilising screws accordingly

Top Servo Assembly

Position Servo in slot as shown, with Servo spindle at the top.Secure with two M4 x 12 set screws and nuts.

Spindle

Top Arm Assembly

Fit top arm onto servo spindle but do not secure with screw until after calibration.

Servo Attachment

Press fit servo attachment to servo motor but do not secure with screw until after calibration

2.5 mm Brass Rod

Using a pliers bend an 90 degree angle on the end of the rod approx. 6 mm long.

Remove burrs usinga file

Brass Rod Assembly

Insert brass rod through Servo attachment as shown. Do not cut the other end of rod until after calibration.

Genie Board Connections

Base servo connected to Q0

Arm servo connected to Q1

Gripper servo connected to Q2

Orange/Yellow wire connected to signal in each case

Genie Board ConnectionsConnect Genie Cable to Board and computer.

Power up Genie Board with 6v battery and crocodile clips as shown.

+-

Calibrating Horizontal arm

Write the following program to position servo.

Remove arm from servo.

Run program live.

Position arm so that it is just 10 mm above table.

Press fit on servo spindle and secure with screw supplied.

Calibrating Gripper Movement

Write the following program to position servo.

Run program live.

Position servo attachment so that one leg is at the 12 o Clock position.

Press fit on servo spindle and secure with screw supplied.

Calibrating Gripper Movement

Fit Brass rod through top hole as before.

Close gripper fully and mark position of hole on brass rod using marker.

Bend through 90 degree.Cut rod so that 3 mm of the bend is remaining. Remove burrsNB. This 90 degree bend is in a different direction to previous bend.

Elastic Band

Attach elastic band as shown feed through hole in base and secure using a piece of Diameter 2.5 mm rod. Remove burrs

The elastic band prevents the arm from jerking as it is moving.

Finishing

Completed Robot

Attach rubber adhesive feet onto 5 legs as shown.

Wiring of Hand Controller

Knot on cable to prevent wires from breaking off.
