Tribot - The obstacle avoidance quirky track robot with suspension system. Also makes random R2-D2 like sounds...
About this creation


This is my very own creation - A quirky obstacle avoidance robot which is operated by waiving your hand at it's rear ultrasonic sensors. Likes to "communicate" with R2-D2 like sounds. Can operate on 2 different stance. Self adjusting sensor eyes will self level so that it sees correctly no matter what is the terrain.

The raw materials - Parts from 8547 NXT set + additional suspension kits + Mindsensor parts

Took me a couple of hours to put it together including programming and testing the NXT brick. I experimented with another track design involving 3 wheels on each track. It looks good however performance testing on the ground yields less than satisfactory results due to slippage and power loss. Thus this is the 1st iteration of the design...

See the Tribot in action...

Still have a lot of room for further "personality" enhancement. I will try to find time to build more robots and showcase them here...

Quoting Ezekiel ~ Hello Kelvin, Ezekiel here, I bought an excavator set from you. Cool bot you got there, very techy with the advance sensors. I first thought that your bot could climb stairs or steep slopes. One point you could improve on. The change in the viewing angle of your IR range sensor. In the video it only happens after your bot stops moving, you can make it real time by placing it in a separate loop if you're using the default NXT programming. And you don't really have to increase the torque of your wheels. 1:1 ratio of NXT motors are powerful enough to climb steep slopes.
Hi Ezekiel, thanks for the feedback and suggestions. Your comments shows you are indeed an advanced NXT programmer. Yes, I put this together to test and demonstrate the Mindsensors modules and there are lots of room for improvement. Will post updates here whenever possible. :)
