Colson’s Guide to Wheels, Casters, and Features in Robotics: AMR Designs

Welcome to Colson Group’s latest exploration into the world of wheels and rolling elements, specifically tailored for the realm of mobile robotics. In this installment, we delve into the various designs and applications within autonomous mobile robots (AMRs), showcasing how Colson’s expertise can enhance your projects.

Customer Benefits of AMR Technology

One of the primary advantages of adopting AMR technology is its flexibility in existing environments. Unlike some technological advancements that demand extensive overhauls, integrating AMRs can often be seamless, offering a quick return on investment. However, selecting the right AMR system is paramount to realizing these benefits swiftly. Factors such as payload capacity, battery life, scalability, and compatibility with current infrastructure must be carefully considered to minimize downtime and maximize efficiency. Moreover, AMRs thrive on mobility, which depends heavily on design elements that not only facilitate smooth movement but also align with operational requirements. <4>Factors Impacting Wheel and Rolling Element Selection Regardless of the type of AMR chosen, the wheels and rolling elements play a pivotal role and are subject to various factors:
  • Load per Wheel Data: Understanding the load capacities, including nominal and maximum, is crucial. Finite Element Analysis (FEA) may be necessary for new product introduction (NPI) projects.
  • Operating Speed vs. Tread Wear: Estimating lifespan based on wear tolerance is essential for longevity.
  • Obstruction Height/Impact Duty Cycle: Assessing durability under stress and considering potential obstacles are vital for seamless operation.
  • Operating Environment: Surface type, temperature range, and resistance requirements (such as chemical, UV, or electrostatic discharge) must all be accounted for.

At Colson, we prioritize each customer’s unique application requirements before recommending any design for an AMR. This can include the following elements:

Drive/Traction Wheels

Drive wheel applications vary significantly, from softer durometer designs for enhanced traction on inclined surfaces to harder, wear-resistant solutions for demanding environments. Regardless of the specific requirements, Colson ensures that the drive wheel tread meets industry standards while the core wheel material interfaces seamlessly with the AMR drive system.
