NI appears to be interested in helping me with the project.\u00a0 They are going to try to find a cRIO system that I can use to control the system.\u00a0 If this happens, it will be totally cool.\u00a0 The FPGA side of the RIO will run the motor control loop really, really fast and keep track of the cart and pendulum positions.\u00a0 The RT side of the RIO will run the logic for inverting the pendulum and send the setpoints over to the FPGA side.<\/p>\n
Checked around for cable carriers and prices to keep the cables from flopping around.\u00a0 It is a difficult problem to solve, because the space between the cart and the shelf where the cable carrier has to fit is about 0.7 inches, and the cable carrier has to support two feet of cable.\u00a0 Right now the best solution is from Kabel Schlepp.\u00a0 They are the only ones that can support the full two feet of cable.\u00a0 Their price is in the middle (Gortrac lowest, Igus highest).\u00a0 The only problem is the minimum order of $50, which I am hoping they will waive.\u00a0 Interestingly, Igus does not have a minimum order, and Gortrac has a minimum of $100.\u00a0 The cheaper the carrier, the higher the minimum order.\u00a0 I guess they have to make their money somehow.\u00a0 This is the last thing I will need, so I will wait until everything else is done to see what will work.<\/p>\n
The gears from McMaster came in today.\u00a0 I love ordering stuff and getting it the next day!!\u00a0 The rack gear is pretty big and kind of heavy, but it looks like it will work well.\u00a0 The spur gears are really thick and very heavy!\u00a0 They are going to add way too much mass to the cart.\u00a0 Maybe they can be machined down or something.\u00a0 There is way more metal than I need there.<\/p>\n","protected":false},"excerpt":{"rendered":"
