Abstract
A robot controllable by a portable device, the robot including a head configured to removably retain the portable device, a support removably mounted to the head, and a base mounted to the support, the base including a first wheel coaxially aligned with a second wheel and a balancing mechanism configured to maintain the head within a predetermined range of angular positions relative to a gravity vector based on instructions received from the portable device.
Claims14
A robot controllable by a portable device, the robot comprising:
- a support comprising an extendable member configured to automatically adjust a length of the support in response to height instructions received from the portable device, and thereby adjust a vertical position of a center of mass of the robot during operation;
- a base mounted to the support, the base comprising:
- a first wheel coaxially aligned with a second wheel along an axis;
- a first motor, drivably coupled to the first and second wheel;
- and
- a processor configured to balance the robot by maintaining a position of a vector, extending between the center of mass and the axis within a predetermined range of positions relative to a gravity vector, based on accelerometer data, received from and generated by the portable device, and vertical position data determined from the support, wherein vertical position data comprises the vertical position of the center of mass of the robot during operation.
