Robotic Arm question

Dear Technical I want to add a robotic arm to my robot - something like www.superdroidrobots.com/HD2_Arm.htm. Their arm seems to be just over one meter long. I have asked them what motors they use, but they don't reply. They state their arm can lift 9kg - thus the torque at the base would be around 900kg/cm. I want to create a similar arm. I do not mind if it doesn't have as much torque as theirs does, but 500kg/cm at the base would be great. Do you have any recomendation on what motors or servos would be good for this application? From watching their videos, I calculate their motors to rotate at around 1.5rpm. Many thanks for your help, Andrew Cowan |

Andrew, We do not have any servos of that size, not even close to it. You could try a geared motor like the 1450-322 with a further 10:1 reduction. In theory, the 1450-056 with a 3:1 reduction should also work. This is quite a load on the gearboxes but worth a try. Regards Paul |

1450-056 does look pretty good. Is there a flat on the shaft? Mounting the shaft to the arm sounds like a tricky problem. Andrew |

Andrew, Yes there is a flat on the shaft. It's not just a question of mounting the shaft to the arm, it's the incorporating the extra 3:1 reduction in between. |

I don't think I'd bother with the extra 3:1 reduction - 463200g/cm sounds good enough. It's either that or using servos (with about 22000g/cm for the same price). Maybe even using two at the base? Andrew |
