Automated speed ramp control of stepper motors

Automated speed ramp control of stepper motor acceleration and deceleration using direct memory access (DMA) and core independent peripherals (CIPs) comprises a numerically controlled oscillator (NCO) controlled through direct memory access (DMA) transfers of prescale values used in combination with a clock oscillator to generate clock pulses that are a function of the clock oscillator frequency and the prescale values. This automates changing the frequency of the NCO, thereby controlling steeper motor speed, without requiring computer processing unit (CPU) overhead. The DMA module is enabled during a first number of clock pulses for step speed acceleration, disabled during a second number of clock pulses for normal operation at full step speed, and then re-enabled during a third number of clock pulses for step speed deceleration. A table in memory may store and provide a plurality of acceleration and deceleration prescale values for DMA transfers to the NCO.

A controller may obtain initial sensing data to determine an estimated weight associated with each initial load of one or more initial loads of material carried by an implement. The controller may identify an estimated weigh accuracy metric associated with each initial load and an estimated weight accuracy metric associated with a final load to be carried by the implement. The controller may determine a target weight for the final load based on the estimated weights of the one or more initial loads, the estimated weight accuracy metrics of the one or more initial loads, or the estimated weight accuracy metric associated with the final load. The controller may obtain final sensing data to determine an estimated weight associated with the final load and may cause the implement to perform one or more actions based on the estimated weight of the final load and the target weight.

Locating and attaching interchangeable tools in-situ

Current technologies allow a robot to acquire a tool only if the tool is in a set known location, such as in a rack. In an embodiment, a method and corresponding system, can determine the previously unknown pose of a tool freely placed in an environment. The method can then calculate a trajectory that allows for a robot to move from its current position to the tool and attach with the tool. In such a way, tools can be located and used by a robot when placed at any location in an environment.
