weekend update: here are the plots from the experiment 👇 (Left: linear fit, Right: polynomial fit) Both with R² ≈ 0.999
weekend update: we measured actuator angle -> knee angle mapping on our four-bar linkage using actual hardware. The two plots show how closely the joint angle follows actuator angle. Linear and polynomial fits both yield R² ≈ 0.999, meaning the relationship is surprisingly…

I've always had an intuitive sense that there might be an issue here. Recently, I did some research, and while four-bar linkages have several advantages, they also come with a few drawbacks. These are the ones I found most relevant to what we're doing (i.e., building…
weekend upate: just ordered all the PCBs for the power system... I am so f*ing tired rn; see you all next weekend 👋
weekend update: I've just received all the missing components for the remaining legs. Next weekend, all 4 legs will be assembled 🦿🦿🤖🦿🦿
weekend update: working on a new leg stand to accommodate the redesigned leg and new actuator 🦿
weekend update: "Dad, this actuator isn't working, I told you"
weekend update: it’s the very first version that, of course, doesn’t work... yet
weekend update: this is what the inside of Ayg's battery pack looks like

weekend update: leg v4 🦿 probably the last iteration for this stage
weekend update: body shaming. Currently, 16.55 kg (36.48 lb). This is without 3 legs (specifically shank and thigh, all 3 actuators are attached), batteries (battery packs are empty rn,) and electronics. The total base weight (base is a headless robot without any additional…
