Next steps for my 3-DoF Arduino Servo Robot Arm project?

Hi everyone,

I just finished building my first small 3-DoF robot arm using an Arduino Uno and DFRobot's 16-channel servo driver. I've been experimenting with basic control methods like joysticks and serial commands.

I'm looking for advice on where to take this project next! Should I dive into Inverse Kinematics (IK), add sensors/grippers for automation, or upgrade the control interface (e.g., Bluetooth/Wi-Fi)?

Would love to hear your suggestions or see what similar projects you've built!

Thanks!
