ISRO had given a project to IIT Kanpur to develop a rover to be launched with Chandrayaan-II, which the university's scientists completed in 2010, but the space agency was yet to pick it up and make part payment to the institute, according to its professor.
When asked about the possible reasons for ISRO not accepting the rover, Venkatesh [Prof at IIT Kanpur] said Chandrayaan-II was set to be launched in 2017, which could be why ISRO was not showing any haste in acquiring it.
According to him, IIT-K spent Rs 29 lakh on the project.

Again, it depends..ISRO needs to really deliver wrt the GSLV program. And also the lander design fabrication testing going well. The 2016 target indicates the shortest possible time for the launch of Chandrayaan-2 if everything goes as planned.From the latest pronouncements by ISRO, it seems more like the development of the lander is what's the main hurdle, rather than waiting for GSLV to be qualified.Does anybody have any idea of what the Indian lander will be based on? Will it borrow from the Russian lander design, or will it be an all-original independent design? I'm assuming the former, since it's best to go with what works, but it's not clear how much Russian technology ISRO can get for this, or whether it's even seen as reliable following the Phobos-Grunt malfunction. What have the Chinese used?

Traction control algorithm development and testing for Lunar Rover mobility system.Funding: Vikram Sarabhai Space Centre, ISRO, Trivandrum, Amount: 8 Lakhs (2009 - 2010) Lunar Rover development for testing of vision based navigation and traction control algorithms.Funding: IIT Kanpur, Amount : Rs 30 Lakhs (2009-2010)
Once the project is completed, we will test it on a prototype lunar rover at IIT-K and thereafter the technology will be forwarded to ISRO," added Venkatesh. The final testing and approval of all the components being developed by the IIT-K will be done by ISRO.According to Potluri, of the six wheels of the rover, four can be driven and steered. The rest can only be driven."The six wheels will have 10 motors to manage the movement and steering of the lunar rover," he said, adding that the major challenge will be to bring a co-ordination between all the 10 motors.
The professor said his colleagues at the institute had realised that the project to build the rover, which would pick up samples from the Moon's surface and bring them back to Earth, would cost much more than Rs 7.5 lakh and had initially refused to take it up."However, the then IIT-K Director Sanjay Govind Dhande had insisted that the project would get the institute international fame and that IIT-K would pitch in with the money," he said.
Anyway, why are all those wires hanging off the front of the rover? Are things going to be that way for the final version?
The Chinese rover seems to have suffered a problem with that infamously pesky lunar dust ...
Anyway, why are all those wires hanging off the front of the rover? Are things going to be that way for the final version? How would this rover survive the cold temperatures of the lunar night? Is it supposed to have RTGs like China's does?The Chinese rover seems to have suffered a problem with that infamously pesky lunar dust, which seems fine enough to get into every nook and cranny to gum up moving parts. How can this threat be addressed?Maybe only Arthur C Clarke knows...

Thus, the Chandrayaan-2 Rover solar panel may be expected to see temperature of Teq = - 182.07374 degrees C during the long (20 days) lunar nights at the landing site. And the solar panel temperature saturates soon after ~ 17 hours of lunar nights entry.
The solar panel temperature during lunar night, in this case, can be shown as Teq = 84.85949 K = -188.14051 deg C

Quote from: sanman on 01/28/2014 01:06 amThe Chinese rover seems to have suffered a problem with that infamously pesky lunar dust ...Are you guessing, or d'you have a source that says the problem was because of the dust? AFAIK, they haven't told us what the issue was. I think the only information we have thus far is that the solar panels designed to fold back and prevent the rover from radiating away all its heat - isn't folding back. Check the Chang'E 3 thread.
Abrasive lunar dust is thought to be the cause of the rover's fatal breakdown.
