08:23 AM katsumi: moooooo
09:04 AM rue_mohr: I was casting aluminum yesterday
09:04 AM rue_mohr: the steel mold that Tom_L make worked, takes a bit of effort tho
09:06 AM deshipu: do you have to preheat it?
09:06 AM rue_mohr: no
09:06 AM deshipu: I thought steel changes size a lot with temperature?
09:07 AM rue_mohr: sure
09:07 AM deshipu: how does that affect the cast?
09:07 AM rue_mohr: well, its changing size a lot too
09:07 AM rue_mohr: I think the alum shrinks more than the steel expands
09:07 AM rue_mohr: the parts dont get stuck
09:07 AM deshipu: but at a different rate
09:24 AM katsumi: alum expands with temperature
09:24 AM katsumi: lot more than steel
09:41 AM mithrison: do you guys use ROS for dev?
09:45 AM katsumi: no
09:50 AM katsumi: only used original kuka SW
09:55 AM mithrison: what’s kuka SW?
09:57 AM katsumi: software to program kuka robots
09:57 AM katsumi: lost the name
09:58 AM katsumi: what kind of robot do you want to program
10:11 AM katsumi: so ROS must have the rite package for the bot
10:13 AM katsumi: e.g. for kuka bots ROS has experimental package but missing functions, so i wouldn't prefer it
10:13 AM katsumi: must find out yaself
10:18 AM mithrison: katsumi: I want to build a robot that pick up things
10:20 AM katsumi: build from scratch?
10:22 AM mithrison: katsumi: I think so
10:22 AM mithrison: katsumi: what are other options?
10:23 AM mithrison: I’m thinking of building it on top of another platform robot but I don’t know which one
10:23 AM mithrison: or where to learn about those platforms
11:03 AM katsumi: re
