Hello guys; Here is my first robot arm 5 axis design.The robot will be control through serial interface using microcontroller and PC based. The mechanical parts has been design using software Space Claim. Now im in process to laser cut the body ad maybe i can make is as a product to sell.Wait for another updates and happy robots.Please visit my website here: www.bizbot-technology.myportal.my

below is the video link:

Nice video. Good to see your robotic arm in action.

Good luck with taking your idea into production.

Thanks brother for the enthusiast
HEY THERE! Im from singapore. Guess we are pretty close!

hai there neighbours?how are you?yes we are pretty close, but i live in selangor..maybe Johor nearby to you.Do you interested in robotics?currently i having problem on servo controller. If you see the video file, the arm moves too fast but not really accurate.any suggestions on controlling the servo speed?


Can you upload your video to youtube or another site that provides you an embedded link capability?

Also, if you are a vendor, can you post your shop? At the bottom of the home page on LMR, there is a link for Shops.

Checkout my video.I upload the video that show the robot pick and place relay into a container

in fast way.

and how much do they cost?

All parts and components are designed using CAD software and is tested before cut. That means, i already have my prototype in simulation before i convert to DXF file for laser cut.

The cost is around $100usd..but that not include servo motor..i also sell servo motor.Price USD15 each servo motor. You can go to my website:


There are lots of project but later i will upload.Thanks for the comments.

You're correct, the arm design has 3 degrees of freedom. If either the lower or middle pairs of servos do not move in unison the arm will experience torsional stress at the end-effector plate, resisting further movement.

Is it really 5 axis? I see there's 5 servos, but arent the two bottom servos paired into one axis, and the same with the "elbow" joint. And then one servo as gripper...?

Am I picking nitts now?
