A strap connector, a robotic arm and a robot are provided. The strap connector includes a core, a strap and a pulley. The core includes a belly portion and a neck portion fixed to the belly portion. The neck portion has a width tapering in a direction away from the belly portion. The pulley defines a core chamber in which the core is received, the core chamber is accessible through an opening. The strap is connected to the core and extending out of the core chamber through the opening. The core chamber has two inner side walls opposing each other and extending from the opening. The neck portion is disposed closer to the opening than the belly portion. The two inner walls of the core chamber clamp the neck portion and the strap when the strap is tensioned.

A worm-like soft crawling robot driven by an exergonic chemical reaction, including a body system, an exothermic reaction system and a vacuum system. The body system includes a left head shell, a left flexible body shell, a left reaction chamber, a right reaction chamber, a right flexible body shell and a right head shell. Elastic transmission parts are installed in the flexible body shells in a matched way. The exothermic reaction system includes chemical fuel storage units and exothermic reaction stimulation devices. The vacuum system includes vacuum suction cups, vacuum exhaust tubes and vacuum pumps.

A surgical robot includes robot arms, an arm base, and a control device. Each of the robot arms includes a base portion, a tip portion that can hold a medical instrument, and links. The link adjacent to the base portion is connected to the base portion through a rotational joint. The control device controls the robot arm having at least seven degrees of freedom among the robot arms such that when viewed from a direction parallel to an axial direction of a rotation axis of the rotational joint, a first portion of a first link is located between a second portion of the base portion and a third portion of the tip portion.

Robotic arms and surgical robotic systems incorporating such arms are described. A robotic arm includes a roll joint connected to a prismatic link by a pitch joint and a tool drive connected to the prismatic link by another pitch joint. The prismatic link includes several prismatic sublinks that are connected by a prismatic joint. A surgical tool supported by the tool drive can insert into a patient along an insertion axis through a remote center of motion of the robotic arm. Movement of the robotic arm can be controlled to telescopically move the prismatic sublinks relative to each other by the prismatic joint while maintaining the remote center of motion fixed. Other embodiments are also described and claimed.
