The insect bot is simple to make, and uses a vibration motor as its head, which is powered by a capacitor as its abdomen, which I salvaged from an old toy plane, with specification – 2.8V 5F, you can get one of ebay for a couple of dollars.

Use diodes for the Legs and Antenna , you can also use resistor. All these components are then soldered together on a small etched PCB which forms the thorax of the insect.

Now since we are using a super capacitor to power the insect bot, we will use 2 AA batteries to power it up as shown in the video above.

In addtion Soldering Iron/Solder and a helping hand ,the picture below shows the components you’ll need to complete the build.

The Circuit is pretty simple

• Connect the -ve to vibration motor to -ve of capacitor and also connet this to a male header pin
• Connect +ve of the capacitor to mail header pin
• And the +ve of the  vibration motor to the other header pin
• The jumper acts as switch once the capacitor is charged

Charging the insect bot is simple , use a 2 AA batteries and connect the +ve pin(red wire in the picture) to the header pin connected to the +ve of the capacitor and the other wire to the -ve.

Once done hit the ON button on the AA battery holder and count to 10 as shown in the video above..
