An autonomous solar collector cleaning device includes at least one main shaft, a first driver attached to a first end of the at least one main shaft, and a second driver attached to a second end of the at least one main shaft. The first and second drivers propel the cleaning device along a surface of the solar collector. A first sensor is attached to the first driver to detect an edge of the solar collector, and a second sensor is attached to the second driver to detect the edge of the solar collector. A control circuit maintains alignment of the cleaning device with respect to the solar collector based on outputs from the first and second sensors.

Solar collector cleaning device

Systems and methods capable of selecting and positively grasping objects of interest within a cluttered environment are described. Some aspects of the present disclosure provide for real-time control of a robot that uses various sensors and reacts to sensor input in real time to adjust the robots path. In some embodiments, a robotic item picker includes an end effector having a shaft extending along a longitudinal axis between a proximal end and a distal end, a carriage configured to rotate about and translate along an intermediate portion of the shaft between a proximal position and a distal position, a suction device coupled to the distal end of the shaft, and a plurality of fingers spaced radially about the carriage. The robot may be a t-bot including a longitudinal member rotatable about a lengthwise axis of the longitudinal member, a carriage translatable along the lengthwise axis, and a radial member slidably mounted to the carriage. The end effector may be rotatably coupled at a distal end of the radial member.

Autonomous crop harvester

A photovoltaic (PV) module cleaning system can include a robotic cleaning device and a support system. The support system can be configured to provide a metered fill to the robotic cleaning device. In some embodiments, the robotic cleaning device and include a curved cleaning head. Various techniques for deploying a robotic cleaning device on PV modules include out-and-back, leapfrog, among others.

Solar module cleaner

A system and method for cleaning a collector surface of a solar collector. The system includes a first liquid-dispensing unit configured to deliver a first spray of liquid to the collector surface. The system also includes a brush element having a longitudinal side oriented along a first direction and disposed adjacent to the first liquid-dispensing unit. A first squeegee element is oriented along the first direction and adjacent to the brush element. The first squeegee element, the brush element, and the first liquid-dispensing unit define a first cleaning area. A second squeegee element is oriented along the first direction and separated from the first squeegee element by a gap to define a second cleaning area. The system also includes a second liquid-dispensing unit configured to deliver a second spray of liquid to the second cleaning area located between the first and second squeegees.
