Powering AGVs/AMRs & Supercapacitors

Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) include warehouse transferring robots that carry loads from point A to point B, as well as production line or sorting robots that are consistent performers for monotonous, difficult or dangerous parts of a production process. Both have advantages, including increased production speed and efficiency and 24/7 operation with minimal supervision.

Challenges

  • Charge time that places the AGV/AMR in pause mode for hours
  • Associated capital assets like charging stations and batteries
  • Frequent battery replacement
  • High peak power demands on the grid
  • Malfunctions and damage to robot and/or production line from power outages
  • Richardson RFPD Logo
