Abstract: This disclosure describes systems, methods, and devices related to robot camera control. A robotic device may receive a user input to control a camera operatively connected to the robot device; identify a live-motion filter applied to the camera; identify a filter setpoint associated with the live-motion filter; generate filtered position control data for the camera based on the user input, the live-motion filter, and the filter setpoint; generate joint data for the robot device based on the filtered position control data; and cause the camera to move according to the joint data.

Abstract: A light device for a paint brush includes an attachment bracket sized and shaped to attach to a ferrule of a paint brush. At least source one light is coupled to the bracket and oriented to project a light onto a surface being painted by the brush. A power source is coupled to the bracket and electrically coupled to the light source. A switch is coupled to the bracket and electrically coupled to the light source and the power source. The switch is configured to switch the light source on and off.

Abstract: A paint brush includes a handle having an attachment end and a grip end. The attachment end has an overall width larger than the grip end. A plurality of bristles is coupled to the attachment end of the handle by a resin. An extension extends from the attachment end of the handle into the resin and toward the plurality of bristles. The extension has a substantially planar surface that faces the plurality of bristles. A groove is formed within the extension and has an opening on the planar surface facing the plurality of bristles. The opening is sized and shaped to allow resin to at least partially fill the groove so as to further reduce independent movement of the handle with respect to the plurality of bristles.

Abstract: A paintbrush includes a handle and a brush extending from an end of the handle. A ferrule circumscribes the end of the handle and a portion of the bristles adjacent the end of the handle. A seal is disposed around an interface between the ferrule and the handle to reduce absorption of chemicals by the handle through the interface.

Abstract: A method for making a paint brush includes placing a plurality of bristles inside a sleeve. A resin is applied into the sleeve to contact the plurality of bristles. A handle is inserted into the sleeve to contact the resin. An extension integrally formed in one of the handle or the resin is fitted into a recess formed in the other of the handle and the resin.

Abstract: A method for making a paint brush includes coupling a plurality of filaments to a handle inside a sleeve with the handle extending out of the sleeve. At least a portion of the handle and the sleeve are coated with a substantially impermeable coating to form a seal around an interface between the sleeve and the handle without covering the plurality of filaments.

Abstract: A paint brush includes a plurality of filaments that form a brush head. A handle, having a brush attachment end, can be coupled to the brush head. The handle can have a grip that extends away from the brush head. A coating can cover the brush attachment end and at least a portion of the grip. The coating can form a seal around the handle to resist absorption of chemicals by the handle.

Abstract: A paint brush includes a sleeve circumscribing a portion of a handle and a portion of a plurality of bristles. A plug can be coupled to the handle. The plug can extend away from the handle into the plurality of bristles to form a space between the bristles. An extension and a recess can be formed between the handle and the resin with the extension extending from one of the handle or resin and into the recess in the other of the handle or resin.

Abstract: A method for conducting a group-based activity includes providing a master visual art work suitable for reproduction. A copy of the master visual art work is made and divided into a plurality of divided pieces. Each of the divided pieces is paired with a corresponding blank piece having substantially the same shape as the corresponding divided piece. Each of the pairs is distributed to at least one participant of the group-based activity, and the participants are instructed to reproduce the divided piece on the blank piece using supplies distributed with each of the pairs. The reproduced pieces are collected and assembled to form a reproduction of the master visual art work.

Abstract: A paint brush includes a sleeve circumscribing a portion of a handle and a portion of a plurality of bristles. A plug can be coupled to the handle. The plug can extend away from the handle into the plurality of bristles to form a space between the bristles. The plug can have a concave end that faces the space between the bristles. The concave end and the space together can form a paint reservoir within the plurality of bristles.
