Let's Make Robots Robots

April 11th 2018 Update : The Items Used have changed. I Will Update Soon... project : 17 DOF humanoid Robot

 

 

Components Used :

  • 17 DOF Biped Robot Mechanical Leg Claw Robot Servo Motor Bracket (https://www.hellasdigital.gr/go-create/robotics/robot-mechanical-leg/17-dof-biped-robot-mechanical-leg-claw-robot-servo-motor-bracket/)
  •  arduino mega 2560
  • 32 ch servo motor board (https://www.hellasdigital.gr/go-create/robotics/control-board/32-channel-robot-servo-control-board/)
  • 12 MG996R Servo Motors
  • 5 MG995 Servo Motors
  • 1 Waveshare Accessory Shield
  • 1 Lipo Battery 30c 7.4v 6250mah 46.3wh (http://batteriesdisios.gr/lipo-6250-mah-7-4v-supersportpro-overlander.html)
  • 1 YwRobot Breadboard Power Supply
  • 1 Panel Volt & Current Meter - 0-100V / 0-100A
  • 1 XBee 1mW Trace Antenna - Series 1

 

Im not quite sure if thats the correct battery, but it's a left-over from a previous project, that I think can be used in this project. Please inform, if someone believes its not a good choice, as my knowledge in this field is very limited.

I also have a 5v 4 Relay shield that I am planning to use if the power seems to be not enough

* I am still at the beginning of the project, trying to make a servo move since it is the first time I'm using 32 channel board

* At last I found a way to move the servos, now its time to Assemble the robot..

* Added some more components for better debugging and future problem resolving. Already ordered a SparkFun XBee Explorer USB

and one more Xbee s1 for wireless communication

Any help would be very appreciated..

thank you very much

Thank you so for your input @fred1456, it confirms my suspicions about voltage issues. The same unfortunately happened to me… I I Burned already 4-6 motors. I think I found the solution yesterady, (already I have ordered a voltage regulator hoping to fix the problem).

Thank you again very much.

i have upgrade my own biped

i have upgrade my own biped with 12x JX PDI-6221MG , those servos cost more, but there are so powerfull and dont make noise !

i recommend those.

…

Thank you so much for your input.

Unfortunately as I stay in Greece, I cant find these servos from a greek resseller, I must purchase them from ebay or something, that takes many days to deliver… So I turned to similar, (better quality than MG996R) servos… I will update soon
