Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Low Cost Robot Arm
https://github.com/adamb314/ServoProject
^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.

UPDATE** Fixed problems with 14 servos running on UNO, old post/problem in comments.
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

help with arduino code please? extreme noob at it.
The source code you have there is from the example code here. In the example they give you will see that they are using the variable servonum to tell which of 8 servos they are driving (0 thru 7) in their example.

Servos move towards default set position before correcting towards provided set position. Can anyone provide some insight on what may be happening? Details and code in comments
These six servos are being controlled through an Adafruit servo shield (https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library), with angular setpoints sent over UART, and a default setpoint set at upload time. This variable is then overwritten with new values when a new UART command is sent.

Can't get 2 servos to move at the same time using this code
