The newest and most important features of the LWA 4P are lightness and high versatility. With only 12,5 kg. in weight, it can carry loads of up to 6 Kg.

These features make it the ideal complement for mobile platforms and humanoids. The robotic arm integrates modular servo­actuators of 2 Degrees Of Freedom, called ERB. The LWA 4P module incorporates a power amplifier and a controller, so it does not require an external control cabinet wich is an important advantage in respect to industrial robot arms.

The robot is available in configuration of 6 Degrees Of Freedom. The most remarkable technical feature of the arm are a reach of 610 mm and repeatability of 0.06 mm. Another advantage is its 24VDC power, so it does not require an external large inverter.
