A seed unit for placing seeds into soil is described herein. A seed unit includes a seed meter for singulating seeds, a shaft to deliver the seeds into soil during operation, and an actuator coupled to the shaft. The actuator moves the shaft during operation and the shaft delivers seeds into the soil without a continuous seed trench.

A planter configured for planting a sentinel plant in a field. The planter comprises a first planting system that is coupled to the planter. The first planting system is configured for planting a first sentinel plant having a first sentinel plant characteristic. A global positioning system is communicatively coupled to the planter. The global positioning system is configured for generating a location signal indicative of a location of the planter. A control system is communicatively coupled to the planter. The control system is configured to receive the first sentinel plant characteristic, receive the location signal, receive a georeferenced field characteristic, and control the first planting system based on at least one of the first sentinel plant characteristic, the location, or the georeferenced field characteristic.

A seagrass planting system that includes a planting spike. The planting spike includes: a tine end feature having a converging portion and a base portion having disposed thereon a seagrass securing mechanism for securing a seagrass segment; an alignment guide feature extending from the base portion, spanning from a first end to second end, and including a first alignment edge and a second alignment edge disposed on an area located between the first end and the second end; and force receiving feature extending at an angle relative to the second end.

A LIDAR system for use in a vehicle is provided. The LIDAR system may include at least one processor configured to control at least one light source for illuminating a field of view and scan a field of view by controlling movement of at least one deflector at which the at least one light source is directed. The at least one processor may also be configured to receive, from at least one sensor, reflections signals indicative of light reflected from an object in the field of view. The at least one processor may further be configured to detect at least one temporal distortion in the reflections signals, and determine from the at least one temporal distortion an angular orientation of at least a portion of the object.
