Questions & Answers

Q: What is aerial grasping and why is it challenging for drones?

Aerial grasping is the capability of a drone to interact with objects in the environment. It is challenging because hitting something mid-air can cause disturbances to the drone, requiring control strategies to compensate and ensure safety.

Q: How does the compliance and friction of grippers help in reducing force during collision?

Compliance and friction in grippers help dissipate energy during collision, reducing the magnitude of the force applied. This can prevent damage and increase the duration of the collision, ensuring better manipulation capabilities.

Q: What are the three main goals for designing an aerial grasper for drones?

The three main goals are to minimize weight and inertia, maximize the allowable velocity difference between the drones, and minimize torque applied after capturing the target for safety purposes.

Q: How does the concept of reach bot for planetary exploration work?

Reach bot is a mobile robot with extendable booms as arms. It uses long reach capabilities to navigate difficult terrains and interact with the environment. The extendable booms collapse and extend, similar to a 3D tape measure, providing exceptional reach.
