This paper summarizes Dennis Hong's TED talk, "My Seven Species of Robot," in which Hong introduces seven distinct robot platforms developed by his team, detailing each robot's design, locomotion method, and practical applications. The paper identifies the key ideas presented in the talk — from the tripedal STriDER to the humanoid DARwIn — and reflects on their broader relevance, particularly Hong's argument that creativity must be paired with rigorous study and a sense of enjoyment to produce truly meaningful engineering solutions.
In his TED talk "My Seven Species of Robot", Dennis Hong devotes most of his presentation to introducing each type of robot his team has developed, explaining the dynamics behind how they move and the functions they are designed to perform. He is notably detailed about locomotion — describing how each robot manages to navigate its environment. For several of the robots, Hong also provides background on the creation process and the various stages of prototyping involved in their development.
The first robot Hong introduces is the STriDER (Self-Excited Tripedal Dynamic Experimental Robot). It has three legs and uses passive dynamic locomotion to walk, much as human beings do. Two STriDER prototypes exist; the second featured a lighter design and was the first to walk successfully.
The second species is the IMPASS (Intelligent Mobility Platform with Actuated Spoke System), a robot capable of traversing different types of terrain by adapting its spoke-based wheel-leg system to obstacles in its path.
The CLIMBeR (Cable-Suspended Limbed Intelligent Matching Behavior Robot) uses three legs to scale cliffs and steep surfaces. Its ability to operate in difficult environments makes it well suited for search-and-rescue efforts as well as scientific fieldwork in remote locations.

The MARS (Multi-Appendage Robotic System) is derived from a six-legged robot named LEMUR and builds on that platform's multi-limb design to expand its range of functions.
The ChIMERA is an amoeba-like robot — Hong also calls it "the blob" — that moves by harnessing the potential energy stored in its elastic skin and tension cords. Its fluid, shape-shifting locomotion sets it apart from the more rigid mechanical designs of the other species.
The RAPHaEL (Robo Air-Powered Hand with Elastic Ligaments) is a robotic hand driven by pneumatic actuation. Because it is significantly less expensive to produce than comparable prosthetic limbs, it holds strong promise for prosthesis applications.
