Mini Tank - Radio Controller - Geekservo - Arduino

[oracid]

Thanks to the new Lego compatible Geekservo, it is now within everyone's reach to make a small crawler robot in less than one hour.

With these radio control servos, the association with Lego mechanics and an Arduino board is very simple.

I wanted to develop, here, a radio control application to make this Mini Tank more attractive. Keep in mind that  the range of such a radio controller is 500m to 1000m.

As usual, the program is extremely simple, even simplistic.

Less than one hour - sure - provided "everyone" is one with your imagination and superb skills

I love all your videos and have learned a lot in this one as well!

Very nice, thank you very much. I haven't heard from Geekservo before - this sounds really interesting - as does your little crawler solution!

All the best,

Thank you.
The Geekservo are in different versions :
- grays are ordinary servos with a range of 0 ° to 180 °
- greens are servos with continuous rotations with a reduction of 1/140, 160rpm.
- blues are continuous rotation servos with a reduction of 1/300, 90rpm.
- reds are DC motors, not servos.
The set operates from 4.8V to 6V

Is there a torque reading for the dc motors? Or rpm

[oracid]

I don't know what are the torques of this DC motors, but don't expect much.

If you want big torque, you should use Lego motor.

Note that a continuously rotating servo does not need additional electronics because it is integrated, whereas a DC motor needs electronics.
