The disclosure relates to systems and methods for determining and adjusting an allowable maximum speed of a machine for movement in a workspace. One or more sensors monitoring the workspace are arranged to obtain a three-dimensional view of the workspace. Raw data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and machine as both move throughout the workspace. This captured data is analyzed to determine a safety protocol that includes a maximum allowable speed for each of various axes of movements for the machine, wherein the safety protocol decreases the maximum allowable speed of the machine only along the one or more axes of movement where the movement of the machine approaches the human.

A controller is configured to operate a robot arm at a speed that is equal to or lower than a first maximum speed in a high-speed operation region, and operate the robot arm at a speed that is equal to or lower than a second maximum speed lower than the first maximum speed in a low-speed operation region, and change a collision detection sensitivity between the high-speed operation region and the low-speed operation region so that the collision detection sensitivity in the high-speed operation region becomes lower than the collision detection sensitivity in the low-speed operation region.

The present disclosure provides a method, devices, a numerical control machine, and a computer storage medium for detecting machine processing trajectory space. The method includes: obtaining data of a trajectory AB of a machine processing and spatial data of a specified space area; converting a function of the data of the trajectory AB into a univariate function P=f (u) with respect to a trajectory parameter u; determining a point set U.sub.i of the trajectory AB on an inner side of each curved surface S.sub.i based on spatial data of the individual curved surfaces S.sub.i forming the specified space area and the function P=f (u); and determining a positional relationship between the trajectory AB and the specified space area based on the point sets U.sub.i.

A cover for an automated robot includes elastic sheets that are adhered to each other in a geometry. The geometry is configured to allow the elastic sheets to expand and contract while the automated robot moves within its range of motion. The elastic sheets are attached to the automated robot by elasticity of the elastic sheets. A first group of the elastic sheets forms an elastic collar configured to grip the automated robot at a distal end and a proximal end of the cover in a non-breakable manner such that during operation of the robot, the elastic sheets hold their elasticity and integrity without breaking.

Machines with safety systems are disclosed. The machine may take the form of woodworking machines including table saws, band saws, miter saws, hand-held circular saws, pneumatic chop saws, radial-arm saws, jointers, planars, routers and shapers. The machines may include an operative structure configured to perform a task, where the operative structure includes a cutting tool adapted to move in at least one motion, and a safety system adapted to detect the occurrence of an unsafe condition between a person and the cutting tool and for mitigating the unsafe condition. The safety system may include a detection subsystem and a reaction subsystem. The machine may also include a bypass or override mode where in an injury mitigation system is disabled for certain cuts.
