Jugnoo and Jassi
Jugnoo
is a 2 motor, microcore based walking robot. The circuit
is nicely described on Eric
Seale's website. Jugnoo uses two hacked micro RC servo
motors for actuation and is powered by a set of 4 AAA NiMh
batteries. As in most of my BEAM projects, I spend more
time figuring out the geometry and the component placements
than on actual assembly. This was the first time I tried
to use the inverted pcb assembly technique, where the solder
side of the pcb is made visible. The technique is very popular
among the BEAM builders community and is successfully used
by Solarbotics.
A perfect example would be Mark
Tiden's robots.
A
lot of SMD components were used to keep the look as compact/flat
as possible. It was real fun soldering them on the veroboard.
The legs are bent out of heavy gauge aluminum wires. (They
are popularly used as clothes line here in India) Thick
rubber tubes were used at the tip of the legs to improve
traction.
Unfortunately,
the batteries turned out to be of poor quality. After the
first few recharges, they simply died. Now Jugnoo has to
be powered externally. I am planning to replace the current
batteries with Li Ions in the immediate future.

Jassi
is a 2 motor, Bicore based walking robot. She is more of
a slider than a walker. Her name is inspired from an ex-popular
Indian sitcom. She is ugly yet able.
Jassi's
ugly looks are an perfect example of how sometimes good
planning can indeed go wrong. A good learning experience.
And thats how her better looking cousin Jugnoo was born.
But I am proud of both.
