Parallel Robot
Parallel robots, closed-chain mechanisms with multiple actuators, are studied for their high speed, accuracy, and payload capacity, but also present challenges like singularities and workspace limitations. Current research focuses on optimizing their design for specific applications (e.g., surgery, human-robot collaboration, agriculture) using techniques like multi-objective optimization, co-design with end-users, and novel hybrid architectures combining serial and parallel features. These advancements improve control, safety (especially concerning collisions and clamping), and accuracy, impacting fields requiring precise and fast manipulation in constrained environments.
