Wait what, Chandrayaan II is going to be doing optical terrain relative navigation on landing as well ?

The design of the indigenous lander and the configuration study has been completed by the Space Applications Centre (SAC) and the integration work will be done in Bengaluru
Isro will design the orbiter, which will orbit the Moon at an altitude of 100 km. The mission will carry five instruments on the orbiter. Three of them are new, while two others are improved versions of those flown on Chandrayaan-1 orbiter.
The rover's mass will be about 30–100 kg and will operate on solar power. The rover will move on wheels on the lunar surface, pick up samples of soil or rocks, perform on-site chemical analysis and send the data to the orbiter above, which will relay it to the Earth station
India's second lunar mission, Chandrayaan-2, which is expected to be launched between 2017 and 2018, will have a rover which will operate on the moon's surface for 14 days. "It will function only for 14 days because its instruments are solar powered and the moon will have 14 days of sunlight," he said.
India’s second lunar probe Chandrayaan II will land on moon in 2017 and the country’s first solar mission Aditya L1 is likely to be launched in 2019, Lok Sabha was informed on Wednesday.Chandrayaan II will land on the surface of moon in 2017 and this second lunar mission will help explore the possibilities of signs of extra-terrestrial life, Minister of State in Prime Minister’s Office Jitendra Singh said during Question Hour responding to supplementaries.
It wasn't entirely clear, but they could be RHU (radioisotope heater units) to keep the lander and rover warm during the cold Lunar night.

Did I miss something?

We plan to take Chandrayaan 3 and 4 in near future and we may use nuclear power in those missions. By that time we will be completely ready with the materials and other things
NEW DELHI: Indian Space Research Organisation (ISRO) has decided to put off for time being its plans to use nuclear power to increase lifespan of India's second lunar mission Chandrayaan 2 as there has been delay in getting the required nuclear material from Russia.
The nuclear power is expected expected to increase the lifespan of the mission as life of Chandrayaan 1, launched in 2008, was cut short by two months due to technical problems. Bhabha Atomic Research Centre (BARC) has been also working to make the nuclear material for the mission.
"We had plans to give nuclear power toChandrayaan 2 but now we have decided to put it off for time being as we don't want further delay in launch which is scheduled for 2017-18," said ISRO satellite centre director M Annadurai.
The second lunar mission was l scheduled for launch in 2013 as joint operation between India and Russia. But after failure of Russia’s Phobos-Grunt, mission to probe Maritian moon, it decided to do an internal assessment of its programme.
India then decided to make Chandryaan 2 as a completely indigenous mission with all three components of the mission orbiter, lander and rover made in the country.
"Once we get the material we have to do necessary experiments which will further delay the mission. There has been some delay in getting material from Russia," he said.

Chandrayaan-2 is the second Indian Lunar Mission which will be launched in near future. Chandrayaan-2 consist of an Orbiter, a Lander and a Rover. SPL, VSSC, has the following experiments onboard Chandryaan-2 orbiter and Lander.•CHACE-2 (CHandra's Altitudinal Composition Explorer) onboard Chandrayaan-2 Orbiter•ChaSTE (Chandra’s Surface Thermophysical Experiment) on Chandrayaan-2 Lander•RAMBHA (Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere) on Chandrayaan-2 Lander, which consisting Langmuir Probe (LP), Dual Frequency Radio Science(DFRS) experiment and radio sounder.
CHACE-2 (CHandra's Atmospheric Composition Explorer-2) on Chandrayaan-2 OrbiterThe CHACE-2 experiment aboard the Chandrayaan-2 orbiter will study the neutral composition of the Lunar exosphere from a circular polar orbit of ~100 km. The CHACE-2 instrument will be similar to MENCA. Apart from obtaining mass spectra of the tenuous Lunar exosphere, the instrument will have capability of tracking the distribution of a pre-selected set of species with higher temporal resolution.
ChaSTE (Chandra’s Surface Thermophysical Experiment) ChaSTE is one of the scientific experiment on the Lander of the Chandrayaan-2 mission. ChaSTE is a thermal probe with the objective of making in-situ measurements of temperature profile on the lunar surface up to a depth of 100 mm near the polar region, and the measurements of thermal conductivity of lunar regolith. ChaSTE would be the first-ever in-situ thermal measurements on lunar surface near the polar region.
RAMBHA (Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere)The RAMBHA experiment onboard the forthcoming Chandrayaan-2 Lander mission is a unique payload package that would provide a comprehensive exploration of Lunar plasma environment. RAMBHA is conceived as a suite of three experiments, viz. (i) a Langmuir Probe and (iii) a dual frequency radio science (DFRS) experiment.
Chandrayaan-1 finds signatures of recent shallow moonquakes<snip>The moonquakes may also provide new insights about mechanism of earthquakes, Kumar said adding that ISRO's Moon rover in the Chandrayaan-II mission slated for 2017 should, therefore, carry a seismometer to study these activities in the Schrödinger basin.
we have described the development of the rover and a map generation system for 3D terrain using structured lightfor a six wheel rover navigation problem. A structured light system enables the detection and estimation ofboth positive and negative obstacles. The structured light system is capable of working even in high luxenvironments to deliver highly accurate maps that can reach sub millimetre accuracies
As specified by ISRO, the design of the rover is based on the well proven space rover “Sojourner” that has beendeployed for the exploration of Mars since July, 1997. It has 6 wheels, all of which are driven by DC brushlessservo motors. The front and the rear wheels also have steering motors. The rover has two rocker arms connectedto the rover body through a differential. Each
