Robotic Bee

This is an article about the robotic bee that I made.

The shape of the sculpture is a tripod.

Here is a video of the sculpture movements:

Step 1: Make the Sculpture

I used a rust proof metal silver coloured wire. This was not necessary because the sculpture is not made to dance in the rain. However, this wire is very light.

I purchased three dual shaft motors from eBay many months ago.

I used attached sticky tape around the motor rotors because the wheel holes had a big diameter and the wheels were loosely attached to the motor rotors. You can use either masking tape or clear tape. You can also used super glue.
I used a rubber band with plastic bags to make the sculpture very flexible and light.
The wiring for the three DC motors is a parallel connection, not series.

Step 2: Testing

I applied 1 Amp to motors raising the voltage to a maximum of 20 Volts. This is very risky because the motors can work at 3V and have a maximum voltage of just 9 V. However, because I did not use gears, I had to apply high voltage and high current.

Step 3: Filming

The vibration motion was filmed when I attached my sculpture to a signal generator. Unfortunately the signal generator did not have sufficient current output to drive the three motors. You can try connecting the signal generator output to a transistor coil/relay/motor driver:

This article shows how to connect two diode to protect the transistor from discharge (because you will need to use two diode for motors - they spin in both directions and thus the direction of the generator current can change):

Conclusion

The motion of the sculpture can be further improved by using better toy wheel tyres with a bigger diameter and specially designed type shape for better tyre to ground grip.
Gears will cost more money but are useful. This will allow you increase the weight of your sculpture and thus increase the splitting diameter, demonstrating the flexibility of the sculpture.
