Robots for home, office, school and more!


Industrial collaborative robots are a relatively new challenge. Robots must move and coexist in environments where humans, and other living beings, must be and feel in safety at all times. That issue has been traditionally tackled by addition of extra components to existing solutions, for instance, adding torque sensors to actuators or dressing robotic arms with capacitive sensor sleeves.

On the other hand, in more academic environments, biomimicry in robotics has been a trend for some decades, and  series elastic transmission actuators, which have very similar features to the muscle-tendon-bone system we humans have, are showing increasing advantages:

  • Elastic deformation of transmission allows the robotic structure to passively comply in case of collisions
  • Energy of unwanted impacts can be dissipated in elastic joints of the system.
  • Impacts do not rapidly degrade reducers
  • Mechanical energy can be stored in elastic transmission, resulting in more power with smaller motors and electronics.
  • The structure itself can be lighter
  • Higher efficiency can be achieved

There are however some setbacks that have to be tackled:

  • Vibration is a strong source of perturbation
  • Acceleration variation must be controlled with heavier algorithms than in classic rigid systems
  • Precision and accuracy can be a bigger challenge

DaGmaRobotics is joining these 2 concepts in the most compact possible system we can develop, and to attain this goal, we rethought every feature, from the feedback system, to the reducer, to the motion control, and so on…

In this section of our page we will share with you some of the technologies we chose and explain why!

I guess you will have some fun checking out our EPICdrive, our S-Hall feedback system and some interesting features packed in virtu3D. Cheers!
