Lynx Motion tread system data	The Lynx Motion tread system is (as advertised) a far more robust tread system than the Tetrix Treads. An assembled 32-link x 2" wide lynx motion tread weighs in at 376g; 11.75 g/link (0.0259 lb_m/link). An assembled 6-"tooth" sprocket with a 6mm hub and (4) bolts (4-40 x 5/8" SHCS) weighs 26g (0.0573 lb_m). An assembled 6-"tooth" sprocket with an idler axle with bolts and bearings weighs 31g (0.0683 lb_m). The 32-link belt (main drive) has a measured C-C distance of 14 in. The 16-link belt (fore drive extension) has a measured C-C distance of 5-3/8 in.
Conceptual design of hybrid wheeled/tread drive-train w/ fore-extension	4 in wheels (tetrix) drive well and can climb initial horizontal bars in the lower section of the mountain.

Tasks	Reflections
Milling for chassis	Braden helped cut the parts for the center supports of the new chassie desighn,and also milled parts for the drive train of the chassis Josh completed rough cutting all pieces of the chassis. He plans to mill most of the rough cut pieces on Monday. Josh used the horizontal band saw for a majority of the cuts, while using the vertical band saw for the few plates he had to cut. Daniel milled a 1-inch metal tube in half. Paul the mentor mentored Daniel on how to use the mill. today mentor paul taught trent how to mill for the chasis
Installing Coding Programs	Amal, Snarr, and Trevor were installing the programs necessary to program the robot on Amal's laptop. The installation process for Java, Android Studio, and Android API 19 in 2 hours! Paul the mentor, helped Amal uninstall all of the useless programs on the laptop. Amal did not know how to install Java, Android Studio, GitHub and the Android API 19 Package, all necessary to program our robot. Snarr showed Amal how to install the programs and how to use them.
Installing Android studio and milling	Justin was helping Amal with the computer program, and helping the people mill in the workshop. Justin was milling parts for the chassis.
