Hello,

I’m new with this product and want to learn more about AL5B and BAP 28

Any idea what can I do with BAP 28 to implement in AL5B Robot Arm Kit? :question:

Thank you for your help. :slight_smile:

There is some sample code for the AL5B arm controlled by the BAP 28 on our GitHub:

In particular, this example allows you to control the arm using a PS2 controller and a BAP 28 / Bot Board II connected directly to the servos:

There is also this example is similar, except the BAP 28 / Bot Board II connects to the SSC-32 servo controller board which controls the servos:

thank you for your help. :smiley:

**is it possible if I program the BAP28 inside the robot without using the PS2 Controller? Means that, the robot moving using the program that we input in the robot. ** :question:

*sorry for my English grammar. I hope you can understand. :laughing:

You can add a sensor, and then modify the code to make it autonomous.

Thank you Alan :slight_smile:

but I do not want use any sensor for this robot. what i mean, i want to move the robot in repeat movement without using any external device/controller. just a simple programming, like moving the arm up and down or lifting object in repeat position.

*not very good in programming but still hope to learn the simple programming for this robot. Thank you :slight_smile:

In that case, I’d make a list of moves to make, and then loop through them.

Thank you KM6VV. :laughing:

You need to connect the yellow wire to P15 of the BAP28 chip. See the BAP28 manual:

I think with the development board you are using and the pictures you provided, that means you need to use pin P27 of your board. See the board manual:

11

I’m sorry. what do u mean with P27? which wire that I need to connect? I understand the yellow wire to P15 of the BAP28.

12

What I meant is that because the BAP28 chip isn’t the same size as the socket on your development board, the pins won’t align 100%, especially the ones on the second side of the BAP28 chip.

Based on the picture you provided showing how you have your BAP28 chip inserted into the socket of your development board, I would expect that pin P15 of the BAP28 chip will actually be pin P27 in the row of header pins on your development board.

I hope this clarifies things…

I see… now understand.

now my robot is working when I programmed the BAP28. thank you for all your help. :smiley:
