Hello! I’m not sure I understand the phrase “soft tech”, but Rover uses some large springs for suspension and has big foam tires. I could build active suspension but it dramatically increases the cost and complexity of the robot, which goes counter to my goals. Some low cost active suspension would be helpful though! Right now I’m just focused on keeping the thing reliable. :)
