Discontinued models (RP-ADH series)


RP-ADH series (Discontinued model)

RP series is an ultra-compact robot with the 5-joint closed link struc-ture.
The arm section has been downsized and made highly rigid, allowing productivity to be increased with high-speed operations.
*Production discontinuation: May 31,2021


Compact, High-speed operation and High precision

  • Align the compact controller of the body and the A4 size, space-saving.Possible integration into the high-density arrangement and equipment.
  • 5 links structure adopted. Lightweight and high rigidity of the arm portion.Throughput is significantly improved in the high-speed operation.
  • The closed link structure, has achieved an order of magnitude higher positioning accuracy.It enables precise fine work.

*1) It is necessary to set the acceleration/deacceleration speed appropriately according to the installing load mass.
*2) The cycle time may increase if specific requirements apply such as high work positioning accuracy.
*3) If the conditions (temperature / operation pattern) change, the position repeatability may increase.
*4) To use the tool (hand), the air hand interface is required.

*1) Please use the controller with an input power supply voltage fluctuation rate of 10% or less.
*2) The power capacity indicates the rating for normal operation. Take note that the power capacity does not include the currentbeing input when the power is turned on.
The power capacity is only a rough guide and whether or not operation can be guaranteed depends on the input power-supply voltage.
*3) This controller is a general environment specification.
*4) The robot must be grounded by the customer.
