A outdoor robot includes an execution apparatus and an execution motor for driving the execution apparatus to perform a work task. The control method includes: obtaining a load parameter of the execution motor during running of the outdoor robot; calculating a change rate parameter of a load; and when it is determined that the change rate parameter of the load represents that the load increases and the change rate parameter of the load exceeds a preset threshold range, braking running of the execution apparatus.

A portable bale breaker and potting apparatus is provided. Soil bales or blocks may be loaded onto an inclined bed and conveyed to rotating breaker bars that break the soil apart into loose soil. The loose soil is conveyed by an auger into a chute which deposits the loose soil into pots on a conveyor belt positioned below the chute. Rotating brush heads downstream of the chute remove excess soil from each pot. The apparatus includes a soil management system for recycling loose overflow soil back to an upstream position on the bed.
