Beschreibung

The most important modification we have made to the moveo robot arm is changing the stepper motors for DC motors (25 Kg/cm & 12 Kg/cm) along with a potentiometer doing the function of an encoder. So we have had to make some changes to the original project, those are:

-Added a Raspberry Pi to interpolate the movements and control the arm.
-Attached the A axis motor support to the arm base.
-Attached Arduino and raspberry case to the arm base.
-Changed the size of the bearings to use a cheaper size (608z), except for the tensors bearings which are the 624z size.
-Changed the motor from the C axis for another more powerful, like the B axis motor.
-Made an special H-bridge board to control the axis with our own firmware (still in progress).
-Put internal fans to cool down the H-bridge board.
-Plus some small frame modifications for better assembly.

12 KG CM

*this work is in progress until the factory ship us the rest of motors (bad days for the shipping company...), then we finaly update it with all the information, videos and finished firmware.
