Hi guys,
Today, i bring to you my hopper-flopper robot. This robot looks so funny and can move on all surfaces. It could be a fantastic toy for your kid. Now, let do your own one. I will instruct you step-by-step.

If you are not clear about steps in this post, you can watch how i made this robot on Youtube

Having any questions, feel free to ask me in comment box below.
Now let's get started.

Step 1: Make the Legs

Firstly, you need to make two legs for your robot. To make these legs, find a water-pipe, cut a ring-shaped from that tube. Then, use scissors to cut the rings into two parts.

Now, using glue gun to draw some lines on the surfaces of the legs. Thank to that, your robot can run on almost surfaces or terrances.
Be careful because you can get hurt from glue gun.

Step 2: Stick Leg to the Motor

I use gear-motor in this project. You can buy one easily on ebay or amazon. Now cut few small pieces of plastic then stick them to motor arm. After that, stick the legs to those plastic parts. You finish robot's legs

Step 3: Make Front Wheel

Front wheel is very important because it keeps robot balance. I use two bottle tops to make the wheel by sticking them together. Make a hole on the both sides of the tops with an aluminum stick. Now you have a front wheel. Make sure your wheel move smoothly otherwise your robot will flip up-side-down.
