A robot for space exploration
A recent invention of a robot that can jump like a grasshopper and roll like a ball could play a key role in space exploration. The ‘Jollbot’, created by Rhodri Armour, PhD student from University of Bath, can jump over obstacles and roll over smoother terrain, could be used for space exploration or land survey work. One of the major challenges that face robots designed for space exploration is being able to move over rough terrain. Robots with legs are generally very complex, expensive to build and control, and encounter problems if they fall over.
Wheels are a simpler solution to this, but are limited by the size of obstacles they can overcome, said a Bath release. The ‘Jollbot’ is shaped like a spherical cage which can roll in any direction, giving it the maneuverability of wheels without the problem of overturning or getting stuck in potholes. It is also flexible and small, weighing less than a kg, which simply means that it’s not going to get damaged while landing or after jumping and would therefore be less expensive.
Virus reaches space!
None of us doubt the potential of computer virus’s these days, but one virus has amazed even the most experienced computer users. It will be the first virus to cross the atmosphere into space. NASA has confirmed that some laptops on the international space station are infected with the W32.Gammima.AG virus, which is a worm and its function is to steal usernames and passwords for online games.
The virus will not affect any of the International space station’s operations. The W32.Gammima.AG was first discovered by Symantec a year ago. It affects Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP operating systems. Symantec says the virus spreads by copying itself to removable media.
NASA said the investigation about how the virus got onto the ISS laptops will be carried out but the cause may not be made public due to security reasons.
The potential a lot of virus’s have, and how vulnerable such large and sophisticated systems are, are the facts that have made the security industry the fastest growing in the IT field.
