Hello, greetings to all robot builders, I am eager to receive the board ez-b, to give life to my butler robot, robot weighing 2.5 to 3 kg, the wheel servos are 15kg of torque, modified for continuous rotation, arms and head as well these servos, body materials are cheap and easy to find, I have a lot of ideas for the project that I'd like to share. Ping 3 sensors and 1 sharp infrared, head with 2-axis motion, arms opening and closing hands, voice, etc. .. And all thanks to the fantastic product ez-b, which by its ease and flexibility, have encouraged me with this project, since my childhood I came in my mind. Here is a video with the current assembly.

Glikclik Thanks! sometimes build a robot from scratch is not complicated, and find inexpensive plastic containers, and there are many sizes and colors. Add more progress soon: Bluetooth external antenna and battery voltage indicator! greetings.
Try these circular LEDs.
Its different.

Maybe some multicolor EL wire lights under the brain dome. :}
R2D2, thanks for sharing all the info on your bot! I believe you were the first to post about your project in these forums and have probably inspired a lot of people with their designs, keep it up with the great ideas! I don't think I would have ever thought of using such common products such as a garbage can in my project, but after seeing your bot I will always consider it from here on in. Thanks again for your contributions!
Bluetooth external antenna. I had problems reaching the robot to turn the hallway of the house was lost wireless signal, then connect an antenna of 2.4 GHz with a piece of coaxial cable (50 ohms) 30 cm long in my case, only the inner cable to the antenna and Bluetooth circuit, cutting the original track integrated antenna with a knife. The theory says that the outside cable must be connected to the negative pole to the coaxial cable does not act as an antenna, I have not only the inside and it works. the extent of signal has been multiplied by 4! 4 to 16 meters! Now the robot can move around the house without problems radio signal.
The voltage meter for Li-Po battery is cheap and you can find for example here:

Dude that is awesome!!!
I found a great source. www.l-com.com/productfamily.aspx?id=6350 Check out the one on sale for $4.50 I ordered mine. Shipping is 10+ so you may want to look around to find some other stuff you may need. Regards, Roger the bookmaker
The wavelength of 2.4 GHz is 125mm, a length of cable that connected to the coaxial cable length and the outer area of the robot, is enough, I understood a piece of thin wire wrapped in plastic. I hope that our robots may soon neighbor's house and further away!
OMG you guys are brilliant
I love it!
