Questions & Answers

Q: What is the main objective of computational design for robots?

The main objective is to make robot design more accessible and allow anyone, even non-engineers, to create their own custom robot designs by providing assistance in specifications and decision-making.

Q: How do robot design and task specification relate to each other?

Robot design involves describing the physical structure of the robot (links and joints) and task specification defines the environment in which the robot will operate and the objective it needs to achieve.

Q: How does compliance play a role in enhancing robot capabilities?

Compliance allows robots to manipulate energy efficiently, leading to improved performance and capabilities. Compliance can be achieved through the design of compliant mechanisms and reconfigurable structures.

Q: How does the use of topology optimization contribute to robot design?

Topology optimization is used to design complex structures that provide specific mechanical responses. By modifying material density in different areas of a structure, topology optimization can optimize the response according to given inputs and constraints.
