Hello, I am looking to purchase a very simple robotic arm to interface easily with an existing arduino module (no motor shield, not looking to get one). I need very simple motion to repetitively pick up a bag and move it a few inches using a programmed routine.
Would the - Lynxmotion AL5B 4 Degrees of Freedom Robotic Arm Combo Kit (No Software) - fit this bill?
Thanks!
Brett
So for the no electronics version are you suggesting that I could just hook it up with just an Arduino motor shield? If something else would be required, could you advise what?
So if I purchased this IO expansion board, I could purchase the no electronics arm kit and control the arm with the digital Arduino pins via this IO expansion board?
It certainly would (depending of course on the weight of the bag). You can opt for a “no electronics” version if you want to use your own microcontroller, but note that it’s much easier to use a shield with 3-pin connectors and separate power for the servos.
The motor shield is not the best for controlling servo motors. Each servo has three wires; signal / voltage / ground. The signal wires go to the digital pins of the Arduino, all of the ground (black) wires go to the GND of the Arduino as well as the GND (black wire) of the servo power supply, and the red wire goes to the power supply’s red (voltage) wire. If you want to wire all of this yourself, you can, but a shield like the IO expansion board takes care of all that. Depending on which arm kit you select, check to see if the power supply (6V, 2A or 3A) is included.
