Abstract
A mobile robotic arm configured to provide on-demand assistance is disclosed. In an example, a robotic system includes a platform, at least two wheels connected to the platform and driven by respective motors, a robotic arm having a base that is connected to the platform, an end-effector connected to the robotic arm at an end opposite the base, and a processor communicatively coupled to the respective motors, the robotic arm, and the end-effector. The processor is configured to cause the robotic arm to grasp an item with the end-effector, receive a command from a user device indicative that the item is to be brought to the user, and cause the respective motors to move the platform so that the end-effector is within proximity of the user device.
