#Antdroid Hardware Components Antdroid is a robot designed to be 3D printed.
It is designed in CATIA V5r21 with a full parametric design, witch allows you to easily resize and adapt the model to your own servos or hardware requirements.
Unfortunately, CATIA is not a free opensource program, so if you want to modify it, you will need a license. We would like to port it to a free software solution but, at the moment, it is not posible.
3D printable parts
All the parts have been exported to stl format, so you can easily print them.

| Component | Number |
|---|---|
| Towerpro MG996R 10kg Servo | 18 |
| Lipo Battery (2S or above) | 1 |
| XT60 Connector (Male) | 1 |
| YEP 20A SBEC | 1 |
| Arduino Mega 2560 r3 | 1 |
| Arduino Mega Proto Shield R3 | 1 |

| USB Wifi | 1 |
| Raspberry Pi Camera Board | 1 |
WARN: To date, Raspberry Pi(RPi) B+ and RPi 2 have been released. Due to design specifications, the AntDroid frame can ONLY hold RPi B (NOT model B+). This is due to the place of the holes that the RPi board have. In fact, RPi B+ and RPi 2 have more holes (4 instead 2). In future upgrades we are going to fix this problem releasing a base to hold the new RPi. Meanwhile, RPi B+ is not supported. NOTE: Now we added a new base to support RPi 2.
Optional
| Component | Number |
|---|---|
| LiPo low voltage alarm | 1 |
| PS3 Dualshock controller | 1 |
| USB Bluetooth | 1 |
| USB hub external power supply | 1 |
WARN: The SBEC doesn't alert of a low battery charge. It is highly recommendable to add a voltage alarm to the LiPo battery in order to not damage it.
The Raspberry Pi B has only two USB ports. One of them is going to be used by the serial connection with the Arduino MEGA. This fact leaves us two connectivity options:
Bluetooth
Wifi
If you want to use them at the same time you will have to buy a USB hub with external power supply because the RPi can not power several devices with a high power consumption.
