MuJoCo Pencil Balancer marketplace
A pencil stands upright in a cup carried by a two-motor planar five-bar linkage. Two fixed cameras about 90 degrees apart watch the pencil against white backdrops, as in event-camera pencil-balancing rigs. The goal is to move the cup under the pencil so it stays upright. Sensors: two cameras, motor encoders, cup position, and a gyroscope and accelerometer on the pencil. Actuators: two position servos at the linkage base. License: Apache-2.0. See model/LICENSE.
