About this model

Teach students how to use ultra-sonic sensors to program a simple obstacle avoidance robot! Lessons and a sample code are attached in the thing files. Scroll Down for the activity information. When my daughter was three she wanted a baby sibling for SCRU-FE ( I said Challenge accepted! and looked through my small robotics parts to make an even smaller and simpler baby robot. Use it for Fun, Programming Practice, or to connect additional sensors for a turtle bot swarm to gather information! This robot uses 9g size continuous rotation servos to simplify design and coding, a #952 Ball caster from Pololu and the treads from #1127 Solarbotics wheels which fit over the round servo horn and have great traction. It allows students to focus more on sensors rather that trying to figure out motor con…
