alks and performs actions randomly. This is the default. The other is control mode where the robot is controlled by iPhone or Android phone via BLE technology. It is the update version of our design [thing:2317065](/thing:2317065) with enhancement in couples of way including design, electronics, software and better guiding instructions to make. Hopefully, it is more fun to make and play.
Full Instructions of making this robot can be found in the [Instructables](https://www.instructables.com/id/Ez-Arduino-MiniKame-Mk2-Making-a-8-DOF-3D-Print-Qu) page. It includes assembly videos (also shown at below) that should guide everyone to make one easily.
We have another [12 DOF quadruped robot](/thing:2901132). You may be interested too.

* a HuaDuino board, it is Arduino Nano compatible with enhanced features. It integrates everything on a single PCB. It's a lot easier for people to make a bot with it. Embedded battery charging circuit, battery charging is more convenient. It can be found on [Amazon](https://www.amazon.com/dp/B07FD59T3G) and [ebay](https://www.ebay.com/itm/292668763845).
* a [single 3.7V 18650 lithium ion battery or battery pack](https://goo.gl/hzss1f) with XH2.54 connector, if you want longer running time getting a pack with two 18650 in parallel. For this robot, you may like to use our design [18650 battery holder](/thing:2943697). However, it is also fine to use [3.7V 10440 lithium ion](https://www.aliexpress.com/wholesale?catId=52805&initiative_id=AS_20180504183051&SearchText=10440+battery) and [3.7V lithium polymer](https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20180504183151&SearchText=lithium+polymer) battery dimension not bigger than W35mm, L70mm & T60mm.
* 8 x [Tower Pro SG90](https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=SG90+) or compatible 9g servos.
