New 3pi+ early adopter - I ordered the kit and the build took a little under 2 hrs, following the instruction video on Youtube. Building the critter was straightforward, and the assembly seemed very well designed, though not too intuitive for someone new to the 3pi line. And the warning in the 3pi+ product listing about being experienced is well advised - I’ve build several racing quads, and while I’ve done closer soldering, you can not rush through this build, and you should be fairly confident of your skills. That said, it’s a fantastic kit, though as the description says, you’ll be doing some programming.
Here is a video of one of the critter’s cuter moments: 3PiPlus_out_of_the_box_2.mp4 - Google Drive
Some additional tools I found useful for the build were - Blue Tack and a Helping Hand to hold parts for soldering, especially the motor leads, because my fingers aren’t as deft as the video presenters’ (my helping hand the big kind with beads on all of the arms), and a flux pen for prepping the contacts for soldering, since flux paste is generally awkward around assemblies, but flux really helps solder flow onto the contacts; a 3/16 combination wrench for tightening the OLED standoffs, and a big dose of concentra - er, coffee.
So I’m planning something like an autonomous mobile robot with obstacle avoidance, like bg305’s fantastic project, except that I don’t have a cat.
