Head Prototype

Qui Du (Manufacturing Engineer)

Objective

Since the 3D head is not printed yet, we realized that if we are to be successful, we need to begin coding the walking frames now.  We want to replicate the final 3D printed head so when we implement the 3D printed head there will be minimal errors with RoFi’s stability.

Materials

I decided to use an aluminum encased designer glasses box because it can easily be shaped and retain form.

Method

I measured the box and cut it to form the size of the SolidWorks 3D printed head. I bent the back of the box to form a battery holder.

Next, I cut holes into the front of the head for the ultrasonic sensor.

I attached the Arduino Mega board under the head top cover.

Figure 4 shows how all components have been organized in the head.

Conclusion

We were able to successfully have RoFi surpass the incline threshold with the prototype head.  We are hoping that replacing the prototype head with the 3D printed head will be successful too.
