The control kit is an Arduino-based development board. The board is designed for 4 degrees of freedom manipulator control, which can control 4 SG90 servos, and with four knobs to control, you can control the manipulator.
Robot arm size: about 6.5*6.5*18cm (length, width and height)
This is a robotic arm produced with 3D printing technology, using 4 sg90 servos, with reasonable design and stable structure.
Features:
3D printing production
The servos are 4 SG90
Easy to assemble
Notes:
1.3D Printing production, there may be burrs, mind the cautious shooting
2. Bulk delivery, need to assemble, poor hands-on ability to shoot carefully
