IBusBM VS ServoProject

IBusBM Arduino Library GitHub Repository

I used the IbusBM library. It works fine, but it requires to use a UART port, and I couldn't simulate with SoftwareSerial. Though the other guys suggested it's something related to the power suplly, I'm still suspect the root cause is the rc communication. Whenever I'm using ibus, it start the jitter. I will give a try to use PPM, because it doesn't shake when the transmitter is connected, while the ibus always shake (weird). The drawback is that my receiver PPM only supports 8 channels and my transmitter has 10.

^Modifying cheap servos so that a robot arm can repeatedly insert a pencil lead. It's a lot of work though.

Most interesting application though fall out of the scope of old-fashioned robotic arms, i.e. when you need to sense the real world in a non controlled context. For instance to develop a robot that can trim wilted flowers, you'll need to measure the real world, and as soon as you do that, you can just sense your robot arm too, no need for fancy, ultra-precise actuators.

Look at this BOM: https://docs.google.com/document/d/1_3yhWjodSNNYlpxkRCPIlvIA...

Do you really need the $6,129.95 & $3,549.95 robot arms for the kind of application described ? I doubt it. I'm not a robotician, and would love some feeback on this idea.

A quick solution is to load the horn, with springs or rubber bands but will reduce total force output. You can theoretically try this implementing this Servo project by Adam Bäckström. https://github.com/adamb314/ServoProject
