Plastic Parts

You might have already played with the plastic parts that come in your kit. There are different plastic parts and accessories that can be categorized into three functions: driving mechanism, internal structure and the Droid shell. Let’s look at some tips and tricks that will ensure you always have a secure fit with your plastic parts.

ORDER OF OPERATIONS

To ensure that all your parts are connected correctly, follow the instructions in the littleBits Droid Inventor app. Certain pieces need to be connected first before attaching others. For example, you will need to build the internal structure before building the outer Droid shell.

 

Plastic Parts Connections

There are a different ways that the plastic parts fit together. Here are some tips to ensure a secure fit.

  • MOUNTING BLOCK TO WHEEL FRAME
    When snapping the mounting block on the wheel frame, use a rocking motion. You should hear a loud snap sound, and the two pieces should feel tightly connected. This connection requires a bit of force, so if you are having trouble, grab a parent.

  • DC MOTOR BIT TO WHEEL FRAME
    Make sure the feet on the DC motor Bit are aligned with the holes on the wheel frame. They should not be facing outwards. Then press the motor down into the clips. You should hear a “snap” sound and the motor should feel very secure. The spike gear should also be touching the drive gear so that when the DC motor spins, so do the wheels.

  • The DC motor needs to be tightly connected in order for you to drive your Droid. To remove the DC motor, pull out on one clip at a time and carefully remove it. This may require a bit of force, so if you are having trouble, grab a parent.

  • BODY BASE TO WHEEL FRAME
    The clips on the body base should snap onto the notches at the front of the wheel frame with a snap sound. Be sure there are no wires in the way as they can interfere with the connection. These two pieces should feel tightly connected – try giving it a shake to make sure they are.

  • BODY TO BODY BASE
    The body has two clips that click into the slots on the body base. You should be able to hear a click sound when you put these parts together.

  • LEGS
    The legs have four pegs on them that can be pressed into the four holes on the body. Make sure you match the R and L on the legs and the body.

  • HEAD
    The head of the Droid can be pressed directly onto the body. You should hear a click sound when you put these parts together. You do not need the neck piece as part of the Base Assembly – this part will be used in missions where you Droid has head movement.

 

DISASSEMBLY

For different missions, you may need to take you Droid apart and reconfigure pieces to give your Droid new functionalities. This is a great way to understand how your Droid works, and is part of the invention process.
