Space exploration has always been an area of fascination for scientists and researchers. Over the years, robotic technology has played a crucial role in expanding our understanding of the cosmos. In particular, robotic arms have proven to be essential tools for space exploration missions. These innovative devices enable precise maneuverability, allowing astronauts and scientists to perform various tasks in the challenging environment of outer space. In this article, we will explore ten groundbreaking robotic arms that have been used in space exploration.

Canadarm2

The Canadarm2, developed by the Canadian Space Agency, is an iconic robotic arm used on the International Space Station (ISS). This advanced system enables astronauts to capture and dock visiting spacecraft, assist in spacewalks, and move heavy payloads with precision. It has become an invaluable asset for assembling and maintaining the ISS.

Dextre

Dextre, also known as the Special Purpose Dexterous Manipulator, is another Canadian contribution to space robotics on the ISS. This highly dexterous robotic arm performs intricate tasks such as fine manipulation, inspection, and maintenance. Equipped with state-of-the-art tools and cameras, Dextre enhances the capabilities of the Canadarm2 and assists in critical space station operations.

Robonaut 2, developed by NASA in collaboration with General Motors, is a humanoid robot designed to assist astronauts on the ISS. This advanced robotic system possesses dexterous hands and can manipulate tools just like a human. Robonaut 2 has been used to test human‑robot interaction in space and has the potential to perform dangerous tasks outside the confines of the space station.

Mars Exploration Rover Arm

The Mars Exploration Rover Arm, used on the Spirit and Opportunity rovers, is a robotic arm specifically designed for extraterrestrial exploration. This arm allowed the rovers to collect samples, analyze rocks and soil, and perform various scientific experiments on the surface of Mars. It played a crucial role in expanding our knowledge of the Red Planet.

Chang'e Lunar Rover Arm

The Chang'e Lunar Rover Arm is a Chinese robotic arm used during the Chang'e lunar exploration missions. This innovative arm enabled the lunar rovers to perform tasks such as sample collection, soil analysis, and terrain inspection on the Moon's surface. It has greatly contributed to China's understanding of Earth's natural satellite.

InSight Robotic Arm

The InSight Robotic Arm, deployed by NASA's InSight lander on Mars, is designed to place scientific instruments on the Martian surface. This arm was instrumental in deploying the seismometer and the heat flow probe, allowing scientists to gather valuable data about the planet's interior structure and seismic activity.

Apollo Lunar Surface Experiments Package (ALSEP) Arm

The Apollo Lunar Surface Experiments Package (ALSEP) Arm, used during the Apollo missions, was an early example of a robotic arm employed in space exploration. Designed to deploy scientific instruments on the Moon's surface, this arm helped measure seismic activity, conduct experiments, and gather data that still contributes to our understanding of lunar geology today.

OSIRIS‑REx Sample Acquisition and Return Arm

The OSIRIS‑REx Sample Acquisition and Return Arm (TAGSAM) is part of NASA's OSIRIS‑REx spacecraft. This robotic arm is equipped with a sampling device that will precisely touch asteroid Bennu's surface, collect regolith samples, and store them for safe return to Earth.

Dragonfly Drone Arm

Dragonfly, a NASA mission planned for launch in the 2020s, will explore Saturn's moon Titan. The Dragonfly drone, equipped with a robotic arm, will navigate the moon's surface and collect samples for analysis. This mission aims to study Titan's organic chemistry and evaluate its potential habitability.

ExoMars Rover Arm

The ExoMars Rover Arm, set to launch in the near future, will search for signs of past or present life on Mars. Equipped with a robotic arm, the ExoMars rover will drill into the Martian soil, collect samples, and analyze them onboard. The arm will also deploy scientific instruments and cameras to further investigate the Red Planet.
