The judges’ ballots are in and we’re proud to present the ten winners of the fourth round of the 2021 Hackaday Prize. We love robots, and it’s obvious that you do too! The number and range of projects submitted this year were overwhelming.
No robotics round is complete without a robot arm, and while a few of them were in the finals, we especially liked CM6, which really pulled out all the stops. This is research-grade robotics on a not-quite-student budget, featuring custom compliant mechanisms so that it can play well with its fleshy companions.
With six degrees of freedom, and six motors, the drivetrain budget can quickly get out of hand on builds like these, so we’re especially happy to see custom, open, brushless-motor driver boards used to reduce the cost of admission. Even if you’re not going to make a 100% faithful CM6 clone, you’ll learn a lot just from going through the build. Oh, and did we mention it has a software stack?
