Step 1: Assemble Walker

Assemble C clamps

  1. Items Required: C-Clamps, Screws, Bolt & Screw driver as shown
  2. Place them as two servo grooves are aligned with each other and screw them together, and make sure the screws and placed are placed diagonally
  3. now repeat the same step until we have obtained 4 pairs of them




Step 2: Mounting Servos to Leg

  1. Place the output shaft of the servo opposite to the circular extrude of the part as shown . Also make sure that the servo wire slides into the horizontal cut of the part with ease as shown
  2. Push the Servo into the leg and once done your part should look as the image shown and now repeat the process until we have obtained 4 pairs of legs

Step 3: Connecting C-Clamp and Servo Mounted Leg

Items Required: Servo motor attached leg part, C-Clamp, Servo Horn, Servo Output Shaft Screw & Screw driver

  1. Connect the servo horn groove side of the C-Clamp to the servo motor as shown and carry out the same steps until you have Four pair of legs

Step 4: Attaching Mounts to Servo

Items Required: Servo motor and mounts

  1. Make sure that the servo output shaft is pointing opposite to the circular knob of the part as shown and make sure to place the servo on top of the part and repeat until you have Four sets of servo mounts

Point to Note:

As shown , there are two different types of servo mount. This is because the joint that connects chassis and legs (similar to our thigh joint) is slightly different with respect to legs. They are labelled as L1 to L4 as shown

Hence, make sure you place the servo correctly with respect to the circular knob present on the part as shown

Step 5: Connecting Legs to Chassis

Items Required:

Chassis, Fully connected leg joint, mounted servo, screws & screw driver

Instructions:-

  1. Make sure that the servo output shaft along with the servo mount is placed on the bottom-side of the chassis as shown. And make sure servo shaft is placed facing backwards as shown
  2. Mount screws from top of the servo shaft output to the bottom of the chassis and fasten with the bolts.
  3. Once the bolts are fastened, attach the knee part with the circle marking on it to the shoulder part as shown. Note that circle on knee should align with shoulder part.

Point to Note:-

  1. For the Walker, note that the following combinations should be attached as shown in image
  2. The L1,L2,L3 and L4 markings are on the chassis, and you can find the square and circle markings on the shoulder and knee parts as shown


Step 6: The Limbs

  1. Fasten both the servo horn support screw and the output shaft screw. Once you’re done, the complete walker leg will look as shown.
  2. Also make sure to take the servo wires to the top of the chassis via the cuts given in the chassis. And your Walker is ready.
