Mechanical-Transmission Technology

Motivation:

Gear transmissions entail drawbacks in robotics applications:

• backlash introduces unmodelled dynamics
• dry friction is unavoidable
• a gear is as strong as the weakest of its teeth
  

Harmonic drives solve above problems at the expense of:

• unacceptable high flexibility
• hysteretic effects that mar the dynamics of robots
• limited applicability: only coaxial shafts can be coupled
  

Conventional transmissions are unsuitable for mechatronic applications.

An alternative solution:

• Speed-o-Cam
• Slide-o-Cam
• Epicyclic Mechanical Transmissions Based on Cams and Rollers
