SpotMicro Part 21

Robot Dog, Part 21.

So it's been about 6 months since I worked on Spot Micro. I the last video I was working on the program side and had some issues with servos slipping in their horns. I was also getting dome voltage drop over the power cable and this was givving some strange results including the servos driving past where the should. To overcome the voltage drop issue, I need to up the supply voltage to that of the batteries and for that I either have to add a large SMPS to drop the 7.4 volts from the batterys to 6V for the servos, something I don't have the space for, or replace the servos with high voltage servos. In this part 21, I replace the servos and sort out the stripped servo horn.

In the first seven videos we built a robot dog based on the Boston Dynamics Spot, only smaller. In part 8, we installed the Bullseye Raspbian OS into the MicroSD card along with Java 11, MRL and WiringPi Part 9 we downloaded and installed the SpotMicro_MRL program and we started looking at how the program worked. In Part 10, we looked at the Servo Services and start the servo calibration process. In Parts 11 and 12, we started looking at the Kinematic programs, more specifically Forward and Inverse Kinematics. In Part 13, we added reinforcement of the Top Arm joints. In Part 14 we started to look at the start of combining the kinematics with coordinated movement controls. In Part 15 as a result of issues with the Rasperry Pi's power when all the servos started moving, I added a capacitor on the Raspberry Pi's Power Supply. In Part 16 I continued with the combining the kinematics with coordinated movement controls and covered some of the gesture controls demo in this at the same time. In Part 17 We looked at Planes of Reference. In Part 18, I had a failure, one of the servo horns for the wrist broke free and cause a servo on the other leg to get too hot. In Part 19, I look at programming with Classes in Python to help control the legs. In Part 20, I continure with the programming in classes to control the legs in both the Robot Pane of Reference and the Inertial Center of Mass Plane of Reference.

You can find the github repository for the SpotMicro_MRL program here: https://github.com/Cyber-One/SpotMicro_MRL The repository not only has the program, but also a list of the parts used.

As part of repository, you will also find the documentation I have been building as part of this robot build. There is also a message posted in the discord whenever I update the program.

Any updates I make to the MRL_SpotMicro program will be included as part of the repository.
