Product Review

Overview:

This 6 axis Desktop Robotic arm includes SainSmart's professional after sales service, with the manual and necessary documentation
included in our wiki site. SainSmart's Robot Arms are perfect for hobby projects to higher level education and robotics research.
CNC machined PVC skeleton provides a lightweight and reliable structure suitable for most smaller projects needing a robotic arm.
This unit utilizes MG996 55g metal gear servos (4pcs) and active joint bearing connections, providing a flexible and responsive robotic arm.
Basic robotic arm programming and mechanics is often used as the "stepping stone" to dive into the industrial robotics and automation
industry, which can fit a wide range of project needs.
