| Below is a complete (sort of)
list of the parts used in Panda Monium, plus the approximate costs of them
to us. This may help others in construction or planning, and it provides
a way for us to feel guilty about the cost of the robot! |

| It's probably fair to say that some of
these sources were not the cheapest, but we used them because they were
convenient for us or quick to order from (eg Electromail). There are definate
ways to keep costs down, for example, by using HiTec rather than Futuba
R/C gear, using Bull batteries and making use of local refuse tips. We
didn't find car boot sales to be very productive, but they are a good source
of tools if you need more. Remember also that things like nuts, bolts,
screws, connectors, drill bits, grinder blades, etc all cost money - and
you will go through a lot of them. |
