A dental robot includes a platform and a suspension system. The suspension system supports the platform and automatically compensates for weights of the platform and a robot arm, end effector, and tooth clamp attached to the platform. The suspension system maintains a constant height of the platform above a base, absent an external force on the tooth clamp. The suspension system allows position and orientation of the platform to change with three degrees of positional freedom and three degrees of rotational freedom, relative to the base, in response to an external force on the tooth clamp, such as a result of movement (change in position and / or orientation) of a subject. A rigid connection between the tooth clamp and the platform ensures that position and orientation of the platform remains fixed, relative to the subject's teeth, in response to movement of the teeth.

A dental robot includes a platform and a suspension system. The suspension system supports the platform and automatically compensates for weights of the platform and a robot arm, end effector, and tooth clamp attached to the platform. The suspension system maintains a constant height of the platform above a base, absent an external force on the tooth clamp. The suspension system allows position and orientation of the platform to change, relative to the base, in response to an external force on the tooth clamp greater than about 0.1 N, such as a result of movement (change in position and / or orientation) of a subject. Consequently, the position and orientation of the platform remain fixed, relative to the subject's teeth, in response to movement of the teeth.
