Motion System Selection Considerations for Wheeled Robots

 As robots become an integral part of our lives in both industry and in our homes, wheeled robots will be at the forefront of the progression. Their motion systems usually consist of brushed or brushless DC motors coupled with compact planetary gearboxes. When selecting a motor and gearbox, you will need to determine both the product’s operating and maximum conditions and confirm the required speed and torque experienced at the wheel output. Here are some tips to consider to help with your selections:

Experimental Approach For Solving Side Band Noise of Miniature Planetary Gearbox

Vibration and noise spectra from miniature planetary transmissions commonly exhibit components at distinct frequencies around the gear mesh (tooth passing) frequency and its higher harmonics, called modulation sidebands. They constitute a significant portion of the vibration and noise generated by the transmission. Sidebands have influence on noise quality measures as well as having great potential to provide valuable clues regarding gear tooth combinations, phasing of planets, manufacturing errors like eccentricity, run out present in the gear set, planet pin position error, etc.
