Abstract: A self-powered vehicle comprises a mechanical drive system, a set of sensors, and a controller coupled to the mechanical drive system to move the vehicle. The self-powered vehicle can operate in a plurality of modes, including a training mode and a smart behavior mode. In the training mode, the vehicle follows a trajectory of a user, and stores the trajectory in memory. In the smart behavior mode the vehicle autonomously traverses the stored trajectory.

Abstract: Provided herein are compositions and methods for intracellular delivery. The compositions are polymer compositions in which the polymer serves as a carrier for therapeutic and/or diagnostic agents. The polymer compositions are effective in targeted delivery of therapeutic and/or diagnostic agents to a cell. The polymer compositions include a targeting moiety that includes carbohydrate groups that effectively target specific cell surface receptors. The polymer compositions also include an agent binding moiety that effectively associates the therapeutic and/or diagnostic agent to be delivered to the cell.
