This version has 12 DOF and uses the following parts:
Arduino Pro Mini 16Mhz 5V
12 x MG92b servos / JX PDI-HV5523
The BIG Version (https://www.youtube.com/watch?v=1nhf8eKKQTI) uses JX PDI-HV5523 HV servos and spot micro (long) body https://www.thingiverse.com/thing:3445283
HV5523 servo constants are 0°:544, 180°: 2400
Lipo 2200mAh 7.4V 25C 2S Smaller original-like version (https://www.thingiverse.com/thing:4015171) works fine with molinoRC Turnigy Nano-tech 950mAh Lipo Akku
MPU6050
PCA9685 servo driver X 2 for HV Servos!
IR remote kit
5 V Buzzer
Optional: JVSISM YPG 20A HV SBEC to bring down the voltage to 6 V.
BM3in1 3 In 1 Lipo Batterie Monitor
0,28 Zoll Mini Digital Voltmeter LED-Display, DC 2,5V-30V
In addition there are more possibilities to control Bela:
-- Incredible Rhasspy and Node-RED for speech control https://github.com/synesthesiam/rhasspy
Raspberry Pi 4
3,3 V to 5 V Shifter
ReSpeaker Mic Array v2.0
Small USB Speaker
-- Using the also the great Web GUI of Leukipp https://github.com/leukipp/OpenCatWeb to control the robot
-- Using the HC-06 Bluetooth RF Transceiver Serial Module to control the robot via Smart Phone (voice and keyboard)
-- Maybe in future:
Robot shall recognize different faces and react (greet, bark, bite :) ).
Using OpenCV
USB-CAM
