Prototype Build Skype Rover Bot

Hey guys,

This is a Skype rover bot to 'play' with my nephew in another country.

Using a developer kit, besides the pan, tilt and gripper servos that i still need to purchase, I am using all parts from the kit and would prefer not to buy anymore.

here is the basic layout.

Yellow are rotational servos, white are lever servos.

As this will be my first build, any tips and hints would be appreciated. Should the arm have a different order? etc.

Thanks in advance for the help.



Upgrade to ARC Pro

Other than be careful with how long you make the arm, it seems okay! The one lever servo which the rest of the arm hinges on won't be able to aim down at all. Just keep that in mind.


Are you using HDD servos? They read HDD in the labels, regular servos read HD.

If using HDD, the arm length is great.


not HDD, they are HD.

so if i should make it shorter? will removing the extensions be enough?

from the EZ-B v4 Developer Kit

the picture from the HDD servos on this site say ezrobot HD, is the picture wrong?


Yeah, the pictures haven't been updated because there are almost 100 of them in various product photos.

The HD servos are noisy and buzz a lot. They're also not great with holding weight for lengthy periods. This may create a negative experience for your robot.

There is an upgrade option for your developer kit. Use the Contact Us and inquire about a discounted upgrade package. I assure you, it's worth it.
