As a total moron, I've deleted the previous robot page while trying to clean some attachments   So, let's start again.. Steve the disembodied robotic arm as been a source of inspiration for me I've found tons of nealy free micro servos on ebay..  so I decided to give a try   For more than a week now, I've been working on my excel simulator, and BS2 implementation of my inverse kinematics algorithm,   which is now able to reach a X,Y,Z target using 4 servos   I've just recieved the servos today ...

So, let's start again..

Steve the disembodied robotic arm as been a source of inspiration for me

I've found tons of nealy free micro servos on ebay..  so I decided to give a try

 

For more than a week now, I've been working on my excel simulator, and BS2 implementation of my inverse kinematics algorithm,

 

which is now able to reach a X,Y,Z target using 4 servos

 

I've just recieved the servos today ;)

 

So I took some foam board and tie wraps... to make something tangible 

 

It's alive ! 

despites the fact that "on paper" the really low torque of those servos could lead it to be a total failure 

 

 

makes noise

  • Actuators / output devices: SG90 micro servos
  • CPU: Basic Stamp 2
  • Power source: Boe Bot
