So this will hopefully be the last update I make before I start buying parts. I've redone the lifter and claw mounts to save weight while maintaining strength, strengthened the point where the actuator meets with the lifter face, and inserted the batteries and ESC's to where I think they belong. I've settled on using the 30A botbitz speed controllers for both sides of the drive, which I feel is enough, although I still need to figure out where to get them if Ranglebox don't have them in stock. I'm going to try to get the Storm S603 receiver (listed below) and connect it via DSM2 with my modified Devo 7E.



At the moment, the HDPE is predicted to weigh approx. 9.4kgs. Adding up the weight of the batteries, ESC's and motors, that adds up to 13.28kg, so it's obvious I'll need to cut some holes to save weight (I already have a few areas in mind for trimming). Also, for some reason, I haven't added in the "wings" on the side of the machine in the CAD, but rest assured, I'm planning to put them on ASAP.





I haven't registered yet to Robochallenge 2017, as I still have these last few details to confirm. But if I think it's possible to have the machine assembled in around 2 months, then that would be absolutely fantastic, and almost a dream come true. I'd love to bring something to Robochallenge, even if it gets absolutely trashed. I'd love to get any feedback on whether or not this design is good enough to work, or at least is in a position to start to be built.
