The exploration of distant planets has always been an ambitious goal, but one which could become a reality sooner rather than later. Recent breakthroughs in robotic technology, combined with advances in space exploration and engineering, have opened the door for robotic spacecraft to potentially collect data and samples from distant solar system bodies. To that end, a team of researchers at the University of Edinburgh have developed a concept video showcasing a robotic arm which, once deployed, could autonomously reach out and collect surface samples from the surface of Mars.
The robotic arm, known as the ‘Pick-Bot’, is capable of travelling up to 30 meters over Martian terrain and can carry objects weighing up to 3 kilograms. The concept video showcases how the robotic arm, powered by a hybrid system of both batteries and solar power, can autonomously grab samples from the Martian surface and deposit them into special collection containers. Once samples have been gathered, the robot can return to the spacecraft for further study.
The vehicle can be anchored to the Martian surface with a grapnel and can wait patiently for the best samples possible to collect. To that end, the team has installed a suite of sensors and cameras to capture, analyze, and identify various geological features and samples of interest. A combination of ultrasonic and infrared sensors ensures the robot will be able to accurately locate and identify samples from locations up to 30 meters away from the spacecraft.
To ensure the robot is able to traverse the rocky surface of the planet, the team developed custom NASA designed composite wheels. The wheels, designed to withstand the tough terrain and dust storms of Mars, offer exceptional grip and can provide the robot with reliable traction. The team also designed special grippers at the end of the robotic arm which can hold onto different samples and carry them back to the spacecraft for processing.
The concept video showcases the potential of this new robotic arm and demonstrates its capabilities of traversing the Martian surface in search of specimens. With its unique sensors and specialized wheels, the Pick-bot is poised to revolutionize robotic exploration of distant worlds and open up myriad possibilities for future space exploration.
