A MPU-6050, for self-balancing.

Bluetooth module – Bluetooth LE (such as HM-10,BT05) for commands sending over from serial console which can be a smart phone App or desktop/notebook computer program; set bluetooth module baud rate to 9600.

Software:

In general, there are 2 steps of sketch uploading, first uploads WriteInstinct sketch and do the calibaration of MPU and servos. Properly doing the calibration is important because it highly affects the locomotion correctness. Second, uploads Nybble sketch which is the main code.
To successfully do the sketch compilation and uploading, supporting libraries must be installed properly to Arduino IDE in prior. If it is unfamiliar to you, this tutorial will be helpful.
