To get two smaller casings from the kit, you’ll need to break one large acrylic piece.
But please, be super careful when doing this to make sure you don’t damage the parts you need.
After breaking it, you’ll end up with two separate pieces of acrylic casings. If you find there’s too much excess acrylic in the holes of the casings, just gently push it out. Remove the protective foil from both sides of the casings now.
Your casings should be all nice and transparent now.
Now, let’s dive into the exciting assembly part! Start by grabbing the casing that matches the one in the photo below and gently place it onto the PCB.
Now, take the battery and check that the plus sign is on the side facing you.
To make sure everything stays in place, we’ll need to secure these casings with bolts and standoffs.
Here’s how you do it: put the bolts in from the front and add the standoffs onto the back. 
Fasten the standoffs with your fingers – no need for fancy tools!
This is what Robby should look like after you put on all of the bolts and standoffs.
Let’s bring Robby to life with some LEDs! You get to choose which LEDs you’d like to add to Robby, so go ahead and pick your favorites. It’s important to pay attention to the polarity of the LEDs as you connect them. Flip Robby around, and you’ll spot those + and - signs next to each connector. These symbols make it super easy to get the polarity right.
Plus and minus signs on the LED are marked with cut-off (-) and rounded (+) parts on the LED.
Click the switch on the right, and the LEDs on Robby’s hands will light up and stay on until you decide to turn them off.
Now, for a real fun surprise, click the switch on the left and give Robby a little shake. His head LEDs will light up and gradually fade off, but don’t worry, shaking Robby again will turn them back on!
We hope you had a blast putting Robby together and maybe even picked up some new tricks along the way.
