Structure of ABB IRB 120 . robot

1. Robot’s engine

A 6-axis robot with a load capacity of up to 3kg (4kg with the wrist bent) and a reach of 580mm, this robot can perform a variety of activities more flexibly than stationary automation solutions. The IRB120 is a system that is perfectly built to be designed for cost-effective applications – especially with minimal space usage.

The robot includes 6 motors to control the robot’s 6 axes, the motor here is the AC servo that is arranged in the robot’s body:

2. Robot’s movement mechanism

Including rotating arms, controlling the robot to rotate in different directions depending on the operating range of each axis.

3. Robot operating range


Operation: 1kg . pick up cycle

  • 25x300x25mm : 0.58s
  • Maximum TCP speed: 6.2m/s
  • Maximum TCP acceleration: 28m/s
  • Acceleration time 0-1m/s: 0.07s

Physical properties

  • Robot base size: 180 x 180 mm
  • Robot height: 700 mm
  • Weight: 25kg
