1. What project are you loading?

2. Have you connected to the EZ-B v4 by pressing the Connect button?

3. Does the EZ-B v4 make the connection sound? Consult this video to hear what the connection sound is: Connection Tutorial

FYI, please create more descriptive subjects when posting. "Need Help" is quite vague

Alright sorry may i know if the way i assembly is wrong or? its walking movement isnt stable it will fall down whenever it start to walk and its starting position is also wierd

Which robot are you using? Have you followed the calibration tutorial and calibrated the servos? Have you fine tuned the servos that still required it after calibration? Are you using the latest version of ARC and loading the latest Example Project for the robot you are using? Have you made any changes to the example project?

Those are just a few questions off the top of my head which require answers before we can really help.

JD, yes i have calibrated it and for now the left and right shoulder have some issues like the waving part the position is like this

Thanks so much for your help!

Nice pic of JD!

Looks like you need to calibrate the shoulders - can you please follow the tutorials on the course page? There are many Lessons that are recommended to follow and become a robot expert

Thanks for the reply and i have already calibrated the shoulder and twice to be sure. I also did follow the tutorial What about the sound coming out from the back of the robot body?
