Martin Raak | 3. March 2017

we supply either components (joints, motors, cables,…) or complete electro-mechanical joint arms. compared to industrial robots, the composition of a robolink joint arm is quite easy and can be reproduced by “everybody”. We show the composition of a 5 DOF joint arm in 3 single video clips: assembly of joints, “motorkits” and “Inikits” (for 0-point reference), […]

For size -20 and -30, the price difference between […]
