Latest Patents:

One of Sakamoto's recent patents involves a construction machine designed to achieve uniform depressing force during compaction work, without requiring complex operations from the operator. This invention features a controller that calculates the front distance, or the distance between the rotational pivot of a boom and a predetermined position in the bucket's back surface. Based on this calculation, the controller determines a target velocity for the bucket, taking into account the front distance. By notifying the operator or controlling hydraulic actuators, the machine achieves the desired velocity and compaction results.

Another noteworthy patent by Sakamoto focuses on a work machine capable of maintaining precise semi-automatic control irrespective of excavation depths and soil conditions. This invention employs a controller that gathers information on soil nature using operation commands, bucket-position measuring devices, and load measuring devices. With this information, a soil-nature map is generated, allowing the machine to calculate an estimated load for efficient excavation and adjust operation commands accordingly.
