I looked into different omnidirectional robot car chassis models. We decided to use a model with four wheels rather than three wheels because we think that a model with four wheels will be easier to control. Additionally, the motors of the four wheel models we found have a greater rpm than those of the three wheeled chassis with no load (330 rpm vs 150 rpm). Dan and I met with Professor Mukherjee to discuss the best option out of the four wheel models and we decided to buy the Moebius 4WD 80mm Mecanum Wheel Robot Car Chassis Kit on Amazon. It the cheapest model we found that meets all our requirements.
Here are some of the kit’s features:
– platform size: 10.24 by 9.06 by 2.56inch, which can load weight 10kg
– 80mm diameter mecanum wheels made of high hardness plastic
– 4pcs DC 12V 330rpm motors equipped with a speed feedback circuit and hall encoder
Hana and I will now look into assembling the kit, powering the motors, and making them rotate using the Nvidia Jetson Nano. I have the Jetson Nano set up with a wireless NIC module which will be used to communicate with the Particle Photon WiFi transmitter on the user’s arm.
