A vertically driving marking robot includes a robot body; at least one magnet constraining the robot to move parallel to a vertical, magnetically responsive surface; a drive configured to displace the robot relative to the surface while the robot is held to the surface; a holder configured to hold a marker; an accelerometer measuring a gravity vector; a computing device in communication with the optical sensors, the accelerometer, and the drive. The computing device includes a processor and computer-readable memory, wherein the computer-readable memory includes non-transitory program code for at least one of the following actions: (a) generating a drift correction to compensate for drive slippage drift in response to and as a function of the gravity vector and (b) commanding the drive to displace the robot along a desired trajectory in response to the drift correction.

A graphic alignment tool and a method of using the same are disclosed. The graphic alignment provides for a placement of a graphic on a substrate. The graphic alignment tool includes a T-shaped center bar having a base vertically disposed and a collar plate laterally disposed at a top end of the base. A width bar is dimensioned to laterally extend across a width of the substrate. A rod is configured to be received in each of the slot and the alignment slot to slidably retain the width bar in a squared orientation relative the T-shaped center bar. A logo grid may also be provided for alignment of a graphic on a chest area of the substrate. The logo grid may be slidably retained with the T-shaped center bar via a rod and a grid slot defined in the logo grid.

Systems and methods are disclosed directed toward the inscription of handwritten notes. The embodiments of the present disclosure enable autonomous or semi-autonomous drafting of words, symbols, letters, or signs on sheets of paper or other material using a pen plotter mechanically coupled with a writing instrument.

Particularly the present invention will allow a detail and precise contour reading and contour marking on surfaces with sharp angles, angles, curves or any difficult shapes, in particular the present invention pertains generally as a mechanism for patented tool: TOOL, METHOD AND MARKING SYSTEM, Canadian Patent No. 2,625,566, U.S. Pat. No. 8,127,457 B2. As the level of difficulty during the wood flooring/tile installation around curved and/or off angle surfaces arises, and there are limited number of workers who can perform such trade, the MECHANISM FOR TOOL, METHOD AND MARKING SYSTEM, will enable anyone who is familiar with the trade to perform the complicated assignment in a shorter period of time and without waste of material; moreover, it will allow performers to acquire the precise craftsmanship results.

The invention comprises a method and apparatus for controlling a marking surface, comprising: a backplate positioned to support the marking surface and a lever arm, the lever arm and the backplate forming a continuous single object, wherein bending the lever arm yields a force transferred through the backplate toward the marking surface, where, optionally and preferably the backplate is at least twice as thick as the lever arm, the lever arm has a flexural modulus in a range of one to ten GPa, and the backplate and lever arm form an angle between thirty and sixty degrees with no applied force. Optionally, the backplate supports a paper of a plotter system.

A gaging apparatus and method for automation of a shoemaking process are provided for automating a shoemaking process. According to the method, the gaging apparatus obtains operation data according to the gaging process of drawing a gaging line on a boundary between the upper and the sole for shoe manufacturing, and generates trajectory data for the boundary based on the operation data. Based on the trajectory data, the gaging apparatus generates robot trajectory data for performing a buffing and bonding process after the gaging process and transmits it to a shoemaking robot.

A drawing apparatus based on a robotic arm includes a bracket, a driving device located on the bracket and a robotic arm connected to the driving device, wherein the driving device consists of two speed-reducing stepper motors, one speed-reducing stepper motor being provided with an upper arm, a tail end of the upper arm being hinged to an auxiliary arm, a tail end of the auxiliary arm being hinged to a drawing arm, the other speed-reducing stepper motor being hinged to a lower arm, a tail end of the lower arm being hinged to the drawing arm, and a head end of the upper arm and a head end of the lower arm being connected through a torsional spring.

A carpenter square includes a triangular body having a first edge, a second edge, and a third edge, wherein the first, second, and third edges cooperate to define a perimeter edge of the triangular body. A fence is pivoted to the first edge for movement among first, second, and third positions. In the first position, the fence is normal to the triangular body in a first direction. In the second position, the fence is normal to the triangular body in a second direction opposite the first direction. In the third position, the fence is coplanar to the triangular body.
