and the no-tech video titles!

I tried several free video editing softwares. They all failed on me, or I did not have the necessary patience to learn how to use them, so at the end of the road I went for the low tech solutions.. And thinking about it I really do like to keep things simple when at all possible.

Very creative.

I am in the process of following your excellent example and building a Delta robot. I am looking at various gripper options. Your vacuum system intrigues me but I am a little confused as to how it works. Could you give us a schematic of the setup please.

Thanks for your contribution

I will make you a schematic of the vacuum system when I get home from work. If I can remember how it worked. The robot does not exist any longer. As an appetizer I will list the main components here: vacuum pump, pressure pump, two solenoid valves, suction cup and vacuum detector. Then some tubes and T-pieces. (now I have a list of what should be in my schematic later)

But that said, please do not hesitate asking questions about it. I did spend quite some time on that project, so I might be able to remember a little here and there.

I wish you good luck on your machine! (and remember to snap some photos while doing it, I forgot that)

Dear Mogul,

I have design and implemented my Delta Robot.

But when I move it to move positions then the moving plate is not parallel to the base plate. It has some tilt in the moving plate.

Can you tell me how I can remain the moving plate always parallel to the base plate ?

Is there any special condition to make the moving plate always parallel to the moving plate ?

Regards,

Zeeshan

Strange, it should be. The end effector, the "plate" that's moves around, should be dead parallel with the base. It should be given my mechanics only. It sounds like you have not made the lower arms as twin arms. Look at the photos again, pay attention to the lower arms, those made of straws, there are six of them, 3 pairs. They are always parallel in pairs.

I think the delta robot is actually so damn cool because of the extreme simplicity in the design, and it's really easy to control as well. I have built many handling robots, but the delta has proven much easier than anything I have tried before.

May I suggest you to enter your robot here on LMR, and add some photos of your creation, then maybe I, or somebody else here, can give you some advises on how to fix your construction.

Show us what you got and lets get that darn thing moving!

Dear Mogul,

Your robot is really coo.

I have one question. Can you tell me the reference point of the motor for your Inverse kinematics. I have read some articles about the inverse Kinematics but no one clearly indicate the Zero Angle of the Motor or Zero Angle Position.

Please tell me the zero angle position of the motor.

Thanks,

Zeeshan

I did not use any reference points other than placing the upper arms horizontal when the servos were in middle position (90 degrees)

Absolutely amazing! Does it work with Skittles or Gummy Bears, too? ;D
