Building the perfect Beast (robot chassis)
February 22, 2012
2012 may be the year of the Dragon for China but it is the year of the robot chassis for me. I am trying to create a new range of robot chassis's and I'd like to know what features my robot building friends would like to see in a chassis. Obviously low cost and high quality are preferable but what else?
For example size? As far as I can see there is already a range of sizes on the market. Is there a size that's missing? I was looking at some cool wheels that were about 250mm (10 inch). Would you want a huge chassis and for what purpose?
Features? Is there a feature that you want but can never find on a chassis? More mounting holes, built in battery charger or motor driver?
Clutches? many gearboxes, even with metal gears can be damaged through accidental collisions or child abuse (the child abuses the robot).
Encoders? single pulse, quadrature, what is the minimum resolution?
Wheels? big, small, thick thin, mecanum, omni, wheels with retractable claws, what is missing from the online range?
To give you some idea of projects I am working on so far:
- Low cost, miniature 6WD Wild Thumper.
- New improved QuadBot chassis with clutches on all servos to protect the gear trains.
- Robot hand/wrist with full range of movement (13 DOF).
- An advanced balancing chassis with sensors.
Tell me what you want in a robot chassis.
