Description: Solarbotic’s Herbie the Mousebot is a 9-volt battery-powered, light-following robot that loves to chase flashlight beams. These little robots are so quick, you have to run to keep up to them! Herbie even has functional whisker and tail sensors, so he doesn’t get stuck in corners, or under obstacles, while chasing around. If there are several Herbies in the same area, they can even be configured to chase each other!

Herbie comes as a build-it-yourself kit that does not use any microprocessors or programming. You’re supplied with all parts as shown in the picture, as well as documentation to put him together. The instructions contain many pictures and simple descriptions to make the building process easy and fun, especially for beginners.

This Herbie has a black body, we also carry a red version.

  • Any idea when these might be back in stock? :)

  • This is a good starter kit to teach someone soldering. However, Herbie has some problems for typical home fun. The big one being the motors are just too fast. In a reasonable sized kitchen you will loose Herbie to stray light in no time. There is no easy way to reduce the speed, a resistor even at 100 ohm is keeps the motors from running at all, and a 68 ohm resistor will burn out or catch fire. However a diode or two (better yet a zener diode tested for best results) will reduce it enough to use it in a typical sized room. Problem 2 is the case of the whisker switches, these switches are hair trigger on even the most light bump floor. Tile, wood (older wood floors where the space is defined between boards.) or asphalt will trigger them and Herbie will be going in reverse all the time (This can be solved with some heat shrink tubing.) The best way to modify the board for the diode/s is by not soldering the positive terminal of the battery to the other boards, putting in a separator and and soldering the desired number of power diodes in line. (the other option is to fly the lead that goes to the motors out to the diode and back to the socket but that is risky.) So in short great soldering and basic electronics device, but really not an optimally functioning product. The design might want to consider including a appropriately rated z-diode to reduce the speed so those of us without auditoriums can have some fun with him without a great deal of hacking.
