Systems and devices for use in executing a tree felling operation are disclosed. A tree felling blade for use in connection with a tree felling operation includes a leading cutter comprising a leading cutter point and a leading transverse cutting blade. The tree felling blade includes a trailing cutter comprising a trailing cutter point and a trailing transverse cutting blade. The tree felling blade comprises a roller portion comprising a concave curvature, wherein the roller portion is connected to the leading cutter and the trailing cutter.

The invention relates to the mounting of knife inserts in apparatuses which require occasional or frequent replacement of the knife insert due to wear or damage of the knife, as is the case in delimbing machinery used in the forestry industry. The invention also relates to a knife carrier, a tree processing head, and to a method of installing a knife insert to a knife carrier. A knife insert for use with a knife carrier includes a blade portion, a retention portion configured to interface with a corresponding receiving portion of the knife carrier, and a force transmission means configured to introduce a preload from the knife carrier to the knife insert, wherein the preload is configured to force the retention portion against the receiving portion along a length of the blade portion and thereby removably hold the knife insert in place in the knife carrier.

Noise reduction in a robot system includes the use of a gesture library that pairs noise profiles with gestures performed by the robot. A gesture to be performed by the robot is obtained, and the robot performs the gesture. The robot's performance of the gesture creates noise, and when a user speaks to the robot while the robot performs a gesture, incoming audio includes both user audio and robot noise. A noise profile associated with the gesture is retrieved from the gesture library and is applied to remove the robot noise from the incoming audio.

A tree shear head assembly is comprised of a connecting frame which provides connecting sections, one of which is angulated at a specific angle to connect to a boom of a motorized vehicle. The connecting frame has a shear structure secured to a lower connecting wall thereof and additional connecting sections for attachment of at least one of a clamping grapple and a tree trunk support fork secured to a support column. The shear structure has a blade which co-acts with a channel formed between gripping plates to immovably arrest a tree trunk being cut by the blade with a slicing action to prevent shattering of the trunk and damage to the tree fibers thereby achieving a clean cut. Different combinations of the shear head assembly with the clamping grapple and/or the tree support fork are easily adapted in combination with the tree shear head assembly.
